In Thiamine Deficiency in Modern Medical Practice and Threats to Thiamine Sufficiency in the 21st Century, I introduced the concept that thiamine deficiency underlies many common conditions plaguing modern healthcare and identified exposures and mechanisms threatening thiamine stability. In Hyperglycemia and Low Thiamine: Gateways to Modern Disease, I summarized the pattern of metabolic changes associated with modern dietary practices that lead to thiamine insufficiency, hyperglycemia, diabetes, cardiovascular and Alzheimer’s disease. In this document, I will tackle thiamine testing.

Background

As discussed in the previous articles and elsewhere on this website, thiamine is a critical and rate-limiting nutrient for several of the cytosolic and mitochondrial enzymes responsible for the conversion of food into cellular energy or ATP. As such, decrements in thiamine ingestion imperil cell function systemically, leading to the onset, maintenance, and/or exacerbation of a host of illnesses.

Thiamine has a short half-life, 1-12 hours, and absent sufficient and/or regular consumption, thiamine reserves will be depleted entirely within 2-3 weeks. The risk of acute deficiency is common after an extended illness where consumption or absorption is reduced, while excretion or metabolism is increased. This includes any illness where nausea, vomiting, and/or diarrhea are present; where intestinal absorption is compromised, such as with Crohn’s, Celiac, constipation, dysbiosis, or gastric bypass; where excretion is increased such as with diabetes and kidney disease; where fever or the severity of the illness increases the demands of metabolism e.g. hypermetabolic states such as sepsis, burn patients, and in critical care cases more broadly where the metabolic demands of the illness itself and the anti-thiamine qualities of many medications overwhelm thiamine availability. Pregnancy, especially when hyperemesis is involved, should also be considered a hypermetabolic state where thiamine deficiency develops more frequently than recognized and is associated with common complications.

Of the studies that have investigated thiamine deficiency in critical care, the incidence range for deficiency varies by study criteria from 10% to 90% upon admission and increases steadily with each day in the ICU. This suggests that even if the patient is not thiamine deficient upon admission, he/she may become so as time progresses.

The progression to severe thiamine deficiency in the face of critical illness will be expedited if the patient’s premorbid health was challenged by chronic illness that included the use of thiamine-depleting medications, and/or where poor diet and chronic alcohol, drug, or tobacco use were present. Subclinical thiamine deficiency or insufficiency may characterize a majority of patients dealing with chronic illness. It is not well defined, but given the chemistry of thiamine against the backdrop of modern diets and medicines, it is logical to presume that many patients dealing with chronic illness consume insufficient thiamine relative to the demands of their metabolism and are but one crisis away from frank deficiency (see Threats and Hyperglycemia documents for details).

Ideally, the recognition and treatment of thiamine insufficiency would be considered before frank deficiency manifests. Unfortunately, current laboratory testing provides neither guidance on subclinical thiamine deficiency or insufficiency nor consistent definitions of what values constitute frank deficiency. As such, a patient tested at one lab may be considered deficient, while at another, may fall within the normative ranges, even if each lab uses the same methods. Similarly, depending upon the testing equipment and methods, the patient’s thiamine status may be more or less sensitive to recent thiamine intake or other confounding variables that skew the results towards sufficiency when in fact the patient is deficient.

Conventional Methods of Measurement

For clinical purposes, the most important thiamine analyte is thiamine pyrophosphate (TPP), also called thiamine diphosphate (ThDP/TDP). Additional phosphates can be added or subtracted to form thiamine triphosphate (TTP/ThTP) and thiamine monophosphate (TMP/ThMP), which are detectable by different laboratory measures, but as of yet, their utility in the clinic has not been fully extrapolated. It should be noted that the phosphorylation of free thiamine into TPP, requires magnesium and ATP, and so, among the factors that will affect TPP values is magnesium deficiency.

Thiamine may be tested from whole blood, erythrocytes, serum, plasma, and urine. From whole blood, all three derivatives of free thiamine can be obtained. Thiamine pyrophosphate accounts for almost 90% of circulating thiamine, 80% of which, is found in erythrocytes. Free thiamine, TMP, and TTP are found primarily in serum, plasma, and urine.

Whole Blood TPP

Whole blood measures of TPP utilize liquid chromatography-tandem mass spectrometry (LC/MS/MS) or high-performance liquid chromatography (HPLC). In the US, the reference ranges TPP from two major labs, Quest Diagnostics, and LabCorp, are 78-185 nmol/L and 66.5−200.0 nmol/L, respectively. Both use LC/MS/MS. Published reference intervals for whole-blood TPP vary widely across labs, however, from a lower limit of 63–105 nmol/L to an upper limit of 171–229 nmol/L. There is no consensus regarding what value constitutes deficiency and little recognition of what may constitute borderline or insufficient thiamine. Under some conditions, TMP, TTP, and total thiamine values will be reported. There are no consistent reference ranges for these analytes either.

Erythrocyte Tests

Erythrocyte tests derived from whole blood samples may measure TPP directly from isolated erythrocytes, such as with HPLC, or indirectly, such as in the case of the erythrocyte transketolase activation test (ETKA). TPP measured erythrocytes using HPLC requires additional laboratory steps, mostly done for research purposes. Reports suggest that HPLC whole blood TPP and HPLC erythrocyte TPP correlate. Similarly, the research suggests that HPLC whole blood TPP and ETKA tests correspond, but there is much debate regarding which one is more accurate.

Unlike the direct assessment of circulating TPP, the ETKA test measures both basal and thiamine-stimulated activity of the thiamine-dependent enzyme transketolase. Test values are reported as a ratio or percentage of enzyme activation. When thiamine concentrations are sufficient, the addition of thiamine will not activate the transketolase enzyme. When thiamine is insufficient or deficient, transketolase activity will increase proportionately to the deficiency. Higher values correspond with the severity of deficiency.

Although there is no consensus regarding what constitutes deficiency for this test either, the continuum of values supports a gradation of need, which may be more useful clinically, particularly with borderline cases and when clinical symptoms correspond. Accordingly, greater than 17% enzyme activation is indicative of thiamine deficiency clinically whereas experimentally, particularly when comparing the sensitivity of different laboratory tools, >25% activation is considered deficient. It should be noted that the ETKA may correlate better with clinical conditions in thiamine-replete patients but may be problematic in patients with magnesium deficiency or when transketolase protein levels are diminished due to liver disease or diabetes.

The EKTA test was considered the gold standard for 50 years, but it is a time and manpower-intensive test, with a high risk for inter-batch variability. As such, and despite its favorable clinical utility, it has fallen out of favor. Currently, the EKTA test is performed only by research institutions and in a few private labs.

Plasma, Serum, and Urinary Tests

Plasma/serum contains only a small fraction of circulating thiamine relative to the erythrocytes and is sensitive to recent intake. As such, tests using plasma or serum are considered less accurate diagnostically but some labs still offer these tests. The reference range for Quest is 8-30 nmol/L.  More commonly, plasma measures of thiamine are used for research purposes. Similarly, urinary measures of free thiamine, TMP, and other thiamine metabolites are used in research protocols involving excretion rates relative to medication, deficiency states, and/or dietary intake.

Challenge Tests of Old

In the late 1960s, a pyruvic acid challenge test was devised to assess thiamine sufficiency in healthy pregnant and pre-eclamptic women. Much like the testing for gestational diabetes where blood glucose is measured before and after consuming glucose, with the pyruvic acid challenge test, blood pyruvic acid concentrations were measured before and after dextrose ingestion. Pyruvic acid is inversely correlated with thiamine status such that when thiamine is low, pyruvic acid increases.

While healthy women exhibited within range values of pyruvic acid concentrations for both fasted and the dextrose challenged portions of the test, pre-eclamptic women, depending upon the severity of the disease process, showed markedly elevated pyruvic concentrations post challenge. The most severely ill women, those hospitalized, had elevated pyruvic acid both pre and post dextrose challenge. Although, to my knowledge this test has not been used in other populations or for anything other research purposes, it illustrates clearly how thiamine deficiency is a sugar sensitive disease.  Should this type of testing be developed more fully, it could identify pending thiamine deficiency before it becomes testable via other methods.

To Test or Not To Test

Thiamine testing is a complicated topic. On the one hand, laboratory confirmation of thiamine deficiency aids in treatment decisions, but on the other, current testing, such as it is, carries the potential for a high false negative rate and may fail to detect anything but the most severe deficiencies. Since there is no consensus on what constitutes deficiency, much less insufficiency relative to diet, illness, or other metabolic variables that contribute to and precede frank deficiency, thiamine testing in some populations may prove unenlightening. In light of these issues, it is tempting to forego testing altogether and proceed directly to treatment based on clinical symptoms. Insofar as thiamine is a safe and essential, water-soluble nutrient, clinical suspicion may suffice and should suffice in acute cases where time is critical. To the extent that medicine strives to be data-driven, however, regular testing, before and during treatment, in conjunction with symptom tracking, may afford much needed insight on the relative value of thiamine in health and disease and may aid in the expansion and refinement of clinical reference ranges.

Postscript: Since this article was published originally, a new version of the transketolase test has been developed: the Erythrocyte Transketolase Activity Coefficient (ETKAC). It is being offered by the Clinical Immunology Laboratory, in North Chicago, IL.

A Life of Low Thiamine Leading to Wernicke’s Encephalopathy

severe thiamine deficiency Wernicke's Encephalopathy

I am a 40 year old male with recently diagnosed, but chronic, severe thiamine deficiency (plasma thiamine <6 nmol/L September 2025) – Wernicke’s Encephalitis. I have all of the classic symptoms like nystagmus, ataxia, and cognitive issues, along with a long list of other symptoms that have accrued over time. I have had a horrible diet since childhood, consisting mainly of fast food, and in my twenties, I drank a fair amount of alcohol. I have also had several bouts of food poisoning, including a c diff infection in August 2025. Antibiotics have been a mainstay since childhood. Once thiamine deficiency was recognized, I was given IM injections and told to supplement orally. I feel worse. Something is missing and I need help. Below is my case story. If there is anyone out there that can help, please comment.

Childhood Marked By Poor Diet, Infections, and Failure to Gain Weight

My youth was filled with many upper respiratory and ear infections that I was giving antibiotics for. I had a “fast metabolism” and could never manage to gain weight, no matter how much I ate. I never wanted to eat the healthy food that my mother would cook and always wanted candy and junk food. I would eat things like lucky charms, brown sugar and apple cinnamon instant oatmeal. By the time I reached high school, I was consuming fast food quite often, and then when I got into sports and weight lifting, I was consuming sugar-filled meal replacements, and protein supplements, and microwave meals.

At 16, I developed a rash on my hands every winter. It would crack and bleed and my joints became stiff. I later learned that this was eczema or psoriasis. I was given a corticosteroid cream. After high school, the rash continued to get worse, and never healed. When I was about 21 years old my hands were so stiff that I couldn’t bend my fingers. They were completely cracked and bleeding all over.

Along with this, my ears, and all of the cartilage in my body, turned solid. I wasn’t even able to flex my ears or ear lobe and every time breathed in it felt like I was being stabbed in my left lung. The doctor diagnosed me with relapsing polychondritis, pleurisy, and psoriasis. High dose corticosteroids and corticosteroid creams were prescribed.

The Poor Diet Continues: Heart Symptoms Emerge

In my twenties, I lived off of cheesesteak sandwiches, pizza pockets, French fries, and soft drinks. I only at couple meals a day and usually skipped breakfast. I worked, partied and fluctuated being not enough eating too much. I lost a bunch of weight and began losing my hair.

In my late twenties, I got a much better job with a lot more responsibility and a lot of stress but my diet was still horrible. I would skip breakfast and then gorge of double orders of fast food meals for lunch. I began gaining weight but I was going to the gym so I’d managed to build an unhealthy muscular physique.

At some point, I began having episodes where I would have my heart racing, chest pain, and other symptoms that felt like I was having a heart attack. Hospital visits concluded that these episodes were panic attacks, however, they did note that my cholesterol, and triglycerides were high.

A Healthier Diet But More Alcohol and More Unexplained Symptoms

In my thirties, I made some changes to my diet. I began eating a healthy breakfast but was still eating out for lunch and having large portions. I added in raw vegetable powders and multiple organ capsules to diet. I also began drinking more alcohol.

My psoriasis flared. I developed random internal vibration episodes and very subtle full body tremors, as well as being jolted awake in the middle of the night. I decided at this point it was time for a change. I tried to eliminate dairy, grains and gluten, chocolate, sugar with the hope that this would resolve my inflammatory issues. Unfortunately, it made matters worse, likely at least partially due to the alcohol consumption.

Magnesium Oxide, a Benzodiazepine and an SSRI

Within about a year, I had lost a significant amount of weight, ended up with significant sleep issues, increased anxiety, and had the worst brain fog of my life. I could not function properly at work and was losing my hair in significant amounts. I visited my doctor who was very well meaning and spent quite a bit of time trying to help. He found that my magnesium was low (1.6), so he gave me magnesium oxide as a prescription. This caused severe loose bowels and just made things worse.

He also told me that I had a genetic predisposition for high adrenaline, and proceeded to give me propranolol to calm that down, as well as a benzodiazepine and SSRI that would “help with my insomnia”. I was not depressed. I just couldn’t sleep and felt like I was in high gear all the time. Instead of doing research and because I trusted this doctor, I took the medication as he advised.

The SSRI made me want to crawl out of my skin, but the benzo allowed me to sleep 6-7 hours, stopped the tremors and being jolted awake. We went through three different SSRI’s until settling on Lexapro. I was on these for about a year until I actually did some research and learned how they were harming my body. I then decided to ween myself off. That process was brutal, with the feeling of brain zaps, worse tremors than before, and intense insomnia.

Brain Fog and Dizziness Worsen

Around this time, a friend and I started a snow removal company. The job was extremely physically demanding. I was out for 24+ hours at a time in freezing temperatures, not only in the truck, but also out shoveling and carrying around a 50lb buckets of salt to spread. I didn’t eat much while out, and lived off coffee, milk and orange juice. We also started going out on the road for weeks at a time, staying in hotels and working 12-16 hour days in food factories, repairing their equipment, and starving myself.  During this time, I experienced some of the worst brain fog I had ever felt. I couldn’t make sense of anything.

In 2016, I discovered the Ray Peat way of living. I eliminated a number of foods from my diet and began consuming a lot of coconut oil, ice cream, milk, orange juice, but at a significant calorie deficit. The diet made me weaker and I wasn’t able to keep up with the business. In 2017, I got a part time job at a grocery store, thinking it would be easier physically but beginning work at 4 am became problematic. The brain fog continued to worsen.

First Bout of Food Poisoning: Cipro and Flagyl Prescribed

Sometime between 2018-2019 I got campylobacter food poisoning from an undercooked burger. I was given Cipro and Flagyl. The Cipro caused joint inflammation and so they advised to discontinue it and finish the Flagyl. After these meds, I had a horrible time concentrating and completing department order at work. I was spaced out while driving, which even led to a couple auto accidents, more frequent tremors that even my girlfriend noticed, and I would randomly wake up with full on shaking, followed by nausea and vomiting. My magnesium still continued at the very bottom of the range, so I started using ReMag in an attempt to move the needle, which mostly just put me in the bathroom. I also started taking taurine, niacinamide, and thiamine HCl. My cholesterol and triglycerides were still elevated.

In 2020, I worked through COVID, as we were essential workers. Luckily, I did not get COVID at this point. I continued taking vitamins, taurine, magnesium, and began desiccated thyroid. I also ate bags of dried organic apricots and mangoes daily. They seemed to help with energy levels.

First COVID Infection and New Onset Food Allergies

In 2021, I began a new job and got COVID for the first time. At that time, I consuming a daily smoothie with full packs of frozen 365 organic strawberries, mangoes, dark sweet cherries, peaches, a cup of orange juice, and Mt. Capra casein protein. The casein protein exacerbated the brain fog. When I eliminated it, the brain fog wasn’t as bad. Odd because I was able to drink milk in the past, just not consume whey protein.

COVID hit hard and took me out for almost a month. I had fever, low O2, and high heart rate. I took aspirin every 4 hours and this seemed to lessen the symptoms pretty quickly. I spent most of my days in bed, eating scrambled eggs, butternut squash soup, chicken soup, and mozzarella cheese. Toward the end of the COVID infection, I developed excruciating pain in my left thigh. I thought it was a blood clot from lying in bed for too long, but an ultrasound ruled that out. The pain and COVID-related shortness of breath remained for about a month. After that everything was back to normal, except now I had food allergies. I could no longer eat the butternut squash soup nor could I eat mozzarella, or the sweet potatoes or French onion soup I would eat prior to getting sick.

Few Good Years with Thiamax Despite Another COVID Infection

Late 2021, I began taking Thiamax to replace the thiamine HCl I had been taking. When I began, I had a little extra brain fog, but I attributed it to the COVID. I also added methylene blue to the mason jar of orange juice I would take with me to work to sip on, along with great lakes collagen. Things started looking up. The brain fog started subsiding and I was able to function at work.

I continued to have the startle awake reactions and tremors. These mostly would happen if I tried to take a nap during the day. Any time I would start to fall asleep, I would be immediately jolted awake and then experience a full body vibrations sensation. This happened every time I started to nod off. I was thinking maybe it was due to the thyroid, but I was still at the very bottom of the level for magnesium when tested.

2022 Was fairly uneventful year, although I did catch COVID again. This time it was very mild and I was only out of work for less than a week. I had all sorts of allergies to food, but the brain fog seemed much improved. The startle awake and vibrations remained and my magnesium was still low.

In 2023, I was in ER early in the year with odd abdominal and back pain, nausea. I thought it could be food poisoning from daily Uber eats lunch orders. Some blood was found in urine. They said it was gastritis and to take Pepcid. The rest of the year was uneventful. I was still taking Thiamax and desiccated thyroid daily. My energy levels were better. I had less brain fog and my body temperature improved. Magnesium was still borderline low but calcium on many blood tests above 10.

Food Poisoning Again and More Antibiotics

Towards the end of October 2024, I got food poisoning again. This time it was salmonella. I had non-stop vomiting and loose bowels for over a week. I was prescribed Flagyl, but did not take it, and Cipro, which I took for 7 days, with gradually worsening joint pain and inflammation. Cipro was discontinued and replaced with Cefixime. A stool test one month later revealed that salmonella had colonized, and they would not give any additional antibiotics to help clear it up. From this point on into 2025, I never felt the same. I had also stopped the Thiamax and was only taking forefront health b-complex and forefront health desiccated thyroid. I was still borderline low magnesium.

The Downward Spiral

By early 2025, I had much worse brain fog, frequently lost train of thoughts, couldn’t concentrate at work, started getting odd reactions to ice cream, mashed potatoes and other foods. They would cause a full body itching, and internal vibrations when I would eat them. Constipation was the norm, and my doctor told me to take two magnesium oxide tablets a day to help, my gastroenterologist told me to take biscodyl daily to help. I started to have a constant feeling like my throat was inflamed.

In May, I was diagnosed with eosinophilic esophagitis. For the endoscopy, I was given propofol and fentanyl for anesthesia. It took over an hour to wake up from and the entire week following, I felt like I had just woke up from the anesthesia. A few weeks later, I was given high dose Omeprazole to correct the eosinophils. I was also advised to eliminate eggs, dairy, wheat, soy, fish, nuts, and corn from my diet.

In June, I received the results for the buccal swap Mitome profile. It showed 404% citrate synthase, normal Complex I, low-normal Complex II, low-normal Complex II-III, and low (24%) Complex IV.

I tried to start implementing the proposed protocol but it seemed to be causing more symptoms. I started tracking glucose, ketones and lactate daily per Chris Masterjohn’s recommendation. I was going out for daily walks and hitting around 8k steps.

A Tick Bite, More Antibiotics, and a C. Diff Infection

In July, I had a bullseye tick bite and the doctor prescribed doxycycline. The doxycycline causing worsening tremors and severe tinnitus, I stopped taking it, after which both began to subside. I was walking daily.

In early August of 2025, I went to the ER with nausea and vomiting. They sent me on my way after doing a CT with contrast and seeing inflammation of the stomach and intestines. They said it was the stomach flu and to stay hydrated. This persisted and worsened for a week and so I was admitted to the hospital. A stool test it was found that I had an active c.diff infection and was colonized with salmonella from the prior food poisoning. I was given ceftriaxone IV, and vancomycin oral.

In addition to the antibiotics, I was given IV’s with sodium chloride and lactated ringers and initially and I felt better. Then they switched over to D5NS, a saline solution that contains 5% dextrose and I felt worse again. Dextrose depletes thiamine and I was already malnourished and thiamine deficient. Nevertheless, within three days of my hospital admission, I was able to consume food by mouth again, around 2,100 calories per day consisting of burrito bowls for breakfast, lunch and dinner, that contained carnitas, rice, pinto beans. I walked the halls doing lunges and calf raises to stay as active as possible.

The morning I was to be discharged I was advised that my magnesium and potassium were both low and given two pills to correct those levels. Vitamin B1/thiamine was not checked. I was also given a 10 day dose of azithromycin.

Severe Thiamine Deficiency Lurking

At discharge, I felt very weak, had tingling and weakness in the legs and severe brain fog. That night at 6pm I took my dose of vancomycin, and my first dose of azithromycin. The next day, I awoke with severe digestive distress continuous diarrhea throughout the day. I returned to the emergency room feeling like I was dehydrated, but they stated that all of my levels were normal and I was discharged.

The following morning, I awoke again with severe digestive distress, and upon standing my heart rate spiked to over 160 beats per minute. I rushed to the kitchen and grabbed some Pedialyte, thinking it was just dehydration, but this made my heart rate beat faster and caused blurred vision. I thought I would faint and I felt an impending doom sensation like I was going to die.

I called 911, and medics arrived and proceeded to perform an EKG, which merely showed sinus tachycardia. They were unable to get my heart rate down in the ambulance, and upon arriving back to the emergency room, I was left to wait for 6 hours before I was able to get any fluids. When they attempted to draw my blood, my veins were flat and they weren’t able to get blood to flow into the vial. This would later become a trend, with blood vessels in the arms and hands constantly appearing shriveled and misshapen, and my mouth felt dry like sandpaper despite trying to drink water.

Oddly, my electrolytes all came back in normal range. My heart rate stayed around 110 to 120 beats per minute the entire wait even while seated in a wheelchair. When I was finally brought into the ER, I was given one large bag of sodium chloride administered rapidly. This initiated a weird sensation in my chest and uncontrollable coughing.

They took me for a CT scan with contrast, and then for a chest x-ray to check for fluid in my lungs, but found none. I was then given a bag of lactated ringers and my pulse began to normalize. During an orthostatic test, my pulse spiked over 100bpm upon standing. They gave me another bag of sodium chloride, performed another orthostatic test and my pulse remained under 100bpm. I was advised to discontinue the azithromycin, and my diagnosis was listed as severe dehydration.

After discharge, my legs were very weak and I had an odd internal vibration, buzzing sensation. My whole nervous system felt very irritated, worse than I ever experienced before. The nerves in my spine and lower back felt raw and like they were being poked. This and tremors, prevented sleeping. I also developed muffled hearing. I was switched from vancomycin to dificid 3 days later.

From that point on, I had worsening neurological symptoms, odd episodes of confusion while driving. I didn’t know where I was even though I was near home. If I looked in the mirror it felt like the room spun. I finished my round of dificid on September 1st.

Increased Need for Sodium and the Continued Downward Spiral

Since my hospital stay, I the only way to keep my heart rate somewhat normalized was to drink several electrolyte beverages or consume large amounts of salt throughout the day. On September 2nd, I developed severe neurological symptoms and diarrhea after consuming a large fruit smoothie.

I noticed that when I ate pulled pork, I would I had more energy and was in a better mood but developed reactions to the garlic and spices used in it. As a result, I switched to a more bland diet consisting mostly of a plain ground chuck, plain chicken with salt, and applesauce.

In mid-September, I added plain white rice to my bland diet with hope of adding more calories. I had lost over 40lbs at this point. The rice probably made matters worse. I developed episodes fuzzy vison. I saw floaters in my eyes, as if I was staring into a bright light. My hearing would go out and I would just have a loud ringing or buzzing in my ears. My pulse would spike to 150 or higher. I became dizzy and felt completely intoxicated, despite not drinking alcohol. Every muscle in my body twitches including my face muscles, and I’ve been told that my eyes will twitch when trying to look straight forward. This is triggered when exposed to heat, bright light, exercise, strong smells or any sort of stimulating experience.

Polyuria and More Thiamine Deficiency Symptoms

In late September, I was excreting around 2L of urine in a few hours despite normal consumption. I went to the ER for IV fluids and then again two days later after having that feeling of impending again. I had white rice for dinner.

I had an EKG, blood work, and was given a potassium in IV, as my potassium was low. They tried to discharge me, but I argued for admission. Nephrology and endocrinology performed a variety of tests. A 24 hour urine test measured 8 liters of urine despite consuming only 2 liters. After urine began to concentrate again, I was discharged. Upon discharge, when I attempted to stand my legs were so weak they almost collapsed beneath me. I felt numb from the waist down.

We Finally Tested Thiamine: Undetectable

That night, I went to a university hospital emergency room and during my 13 hour wait to get in, I desperately searched for answers. I chanced upon hormonesmatter.com and ordered the kindle version of Thiamine Deficiency Disease, Dysautonomia, and High Calorie Malnutrition and began to read. Once a bed was finally ready in the ER, I told them my story and they started running a number of labs.

I was seen by several doctors, neurologists, and a pulmonologist. They ran orthostatic vitals, several blood labs, and upon my doctor’s recommendation they admitted me for observation (he was leaving his practice that day). They did an MRI of my spine, took me for an EMG and nerve conduction tests. In the MRI they noted some slight degeneration in the spine, and red marrow reconversion throughout. EMG and nerve conduction tests were mostly normal, however, they noticed some diminished sensation in my left lower extremities and toes and a mild gait disturbance.

I requested a vitamin B1 plasma test, along with copper, iron, zinc, and others. I was kept for observation for a few days and given IV fluids, which kept pulse fairly normal. The thiamine test had not returned by the time of discharge.

A week later when the result came back, it was <6 nmol/L, which is basically undetectable.

I was extremely excited, finally getting some answers as to why all of these things were happening. The doctor prescribed intramuscular thiamine 500mg in total, to be given daily for a week, followed by 400mg thiamine HCl orally and IM shots every three days for the next two weeks. The first shots were that very night.

Thiamine Repletion Has Been Brutal

After my first dose, I slept well for the first time in months but the next morning when I attempted to stand, my pulse spiked up but my blood pressure tanked to 89/62. I could no longer walk for more than a short distance. I tried to continue my regular 8-10k steps daily, but after a couple hundred steps, my body would completely shut down. My vision became fuzzy, I saw floaters or like flashing lights and my pulse would skyrocket even though it was already high. The Holter monitor recorded sinus tachycardia and some SVT’s. My legs were so weak, they tremor and felt like they were going to give out beneath me and I felt like I could not get enough air in.

This entire time I was getting the thiamine shots, I struggled to consume enough calories on a daily basis.  Surely, eating only 900-1000 calories didn’t help my situation, I just couldn’t eat any more. When the shots were stopped in November, my health declined further. At this point that, I began significantly increasing my dose orally and adding other forms of thiamine. This made everything significantly worse.

By mid-November, at this time I was getting around 300mg of magnesium malate per day, taking a daily multivitamin (Seeking Health One Chewable), as well as Forefront health thyroid B-complex), and only able to eat boiled chicken and applesauce. Anything else made my GI symptoms unbearable and caused worsening tremors and internal vibrations. Per my records, here is the dosing I followed.

  • Week 1 (first 5 days): 500mg IM thiamine HCl shots, once per day.
  • Days 6 & 7 picking up with 200mg of thiamine HCl by mouth twice per day for 400mg.
  • Week 2: 200mg thiamine HCl by mouth twice per day for 400mg, with one 400mg IM shot on Thursday.
  • Week 3: 300mg thiamine HCl, plus 150mg benfotiamine by mouth twice per day, with one 400mg intramuscular thiamine HCl shot on Monday and 400mg IM thiamine HCl shot on Thursday.
  • Week 4: 300mg thiamine HCl plus 300mg benfotiamine by mouth twice per day, with one 400mg IM thiamine shot on Thursday.
  • Week 5: 300mg thiamine HCl, plus 300mg benfotiamine by mouth twice per day, no intramuscular shots.
  • Week 6: 300mg thiamine HCl, plus 300mg benfotiamine by mouth twice per day, no IM shots. Wednesday and Thursday attempted to add morning and afternoon dose of Thiamega and cut benfotiamine back to 150mg and thiamine HCl back to 100mg. This led to extreme anxiety, significant increase in pulse and panic attacks.
  • Week 7: same as above but have begun having random panic attacks, adrenaline surges, pulse spiking to 160bpm randomly. I can’t sleep at all (last week and the weeks before I was getting 7 to 8 hours per night typically). Now I wake up at 2am and feel air hunger and have random surges in pulse, spasms and closing of my esophagus. I went to the ER yesterday and they found nothing wrong. All electrolytes were on the lower end of normal. I have tremors, dysautonomia and POTS symptoms again and I am losing weight again.”

The Hell Continues: Confusion and Food Intolerances

Thinking I was taking too much thiamine, I reduced intake to just 150mg benfotiamine and 350mg thiamine HCl for a couple days. This was right before Thanksgiving. My neurological symptoms were getting worse, and now I was experiencing dizziness, cognitive decline and new vision problems, but the shortness of breath had begun to subside.

I had an appointment to see a nutritionist. I showed up at the appointment and had this new surge of confusion, as well as a significant increase in pulse while walking in, my body felt ice cold even inside the building.

After going over all of the foods that I was having issues with and what my allergist told me to avoid, we were left with almost nothing. She said, at this point you’re going to just have to try to start eating anything you possibly can to add more calories, because you’re lucky if you’re getting 600 calories per day.

As I walked out of the building from this appointment, I experienced the worst brain fog that I had experienced to date. I walked around the entire parking lot but I could not remember where I parked my car. My pulse extremely high and I was dizzy. I felt like I was in a dream and I could not make sense of anything that was going on around me. I eventually found my car about 20 minutes later.

Since I was struggling to come up with ideas of what I could eat and unable to tolerate most of the things that I tried at home, I decided to go back to trying Chipotle. It turns out, I can tolerate Chipotle carnitas. So now, I eat two chipotle bowls with double meat, double brown rice and light beans. It’s nowhere near an ideal healthy meal but at least I can eat – sort of. I now get migraines a few hours after eating and internal vibrations and tremors.

I started taking Zyrtec daily, because I tested positive for a rice allergy on both blood and skin tests. I continue to eat Chipotle and use Zyrtec to manage the allergic reactions. I also take quercetin, a mast cell stabilizing supplement, and butyrate supplement.

Another Medical Procedure With Anesthesia

Mid December, I had a recommended colonoscopy and endoscopy. Given my problems with anesthesia, I was worried. The prep process was very rough on my body and caused even more palpitations and higher heart rate. I don’t think the thiamine I was taking was absorbed and not eating made things worse. Surprisingly, coming out anesthesia was okay, but the first time I tried to drive, I had a major energy crash. I felt like everything was moving in slow motion and my brain was running out of energy would shut down. My vision was fuzzy, my hearing went out and I just had a loud ringing as my pulse spiked up. I felt like I was completely intoxicated. Every muscle in my body started twitching, tremoring and then lost strength. I messaged my neurologist and they responded that it sounds like a panic attack, and I should take some Tylenol for my intense migraine headaches. I was not a panic attack.

I have been unable to drive since. Every time I am in the car with someone going to an appointment, all of the visual stimulation from trying to process cars and what’s going on the road and around me, causes what feels like a mental shutdown. I also feel like I’m intoxicated constantly, especially when in the car, or looking into a mirror. It has gotten to the point where it is hard for me to focus on things mentally, or make sense of things I read or watch. I’m not sure if this is all due to the B1 deficiency or if it’s partially due to the c diff infection and all of the antibiotics.

My Health Is Failing and I Don’t Know What to Do

I am struggling daily to maintain a proper electrolyte balance. If I sip a 33oz coconut water throughout the day and add a little salt here and there, in addition to the sodium I’m getting from food, I end up feeling dizzier, like my blood pressure is too low. If I take 450 mg of sucrosomial magnesium, I still have full body tremors, muscle twitching and a migraine. If I increase the magnesium the twitching subsides, but dizziness increases and I feel faint. I’ve even tried using 350mg sucrosomial magnesium with 144mg of magnesium l-threonate (hoping this would help with brain symptoms.

I’ve tried to introduce healthier foods, such as the farm eggs that I used to eat every morning, ground lamb, fresh-squeezed orange juice, but my body just seems to reject these. So I am left with the Chipotle, with double carnitas, double brown rice, and light pinto beans. I realize these meals are not the healthiest options and probably not doing me any favors with the brain fog, migraines and other symptoms but I don’t know what else to do. Are my continuing symptoms all related to the thiamine deficiency, my diet or something else?

Adding More Supplements

On December 19th, I began taking Lipothiamine. I began with 12.5 mg once at breakfast, along with 150mg benfotiamine, and 250mg thiamine HCl.  For lunch, 150mg benfotiamine and 100mg thiamine HCl. That day I had much more severe dizziness, my head felt like it was in a vice, and I was experiencing lapses in time. I went to the ER thinking maybe it was an electrolyte issue. They said electrolytes looked fine. Potassium and sodium were at the very low end of normal, but they were not concerned. They did a CT of my brain (again) and did not find any irregularities. I was offered a migraine cocktail consisting of antihistamines and morphine or something like that, and they offered to keep me for 24 hour observation. Since there was nothing else they could do for me, so I declined. I was given a bag of sodium chloride and discharged.

On the 20th, I increased to 12.5 mg with breakfast (plus 150mg before/250mg HCl), and then 12.5 mg with lunch (plus 150mg benfo/100mg HCL. I held that dose until December 23rd, when I was able to resume the intramuscular shots.

After the intramuscular shots, I felt like I had more energy, I was much more social, and felt like symptoms had improved slightly. The next day, I increased my Lipothiamine dose to 25mg with breakfast, keeping the same benfo and HCl doses as the prior days. All of the symptoms got much worse. I felt a significant increase in the dizziness, heart rate picked up, it felt like I was walking through a dream.

On December 25th I added another 25mg of Lipothiamine with lunch and kept the bento and thiamine HCl the same (so 25mg lipothiamine with breakfast and 25mg with lunch). Symptoms continued to worsen. I also began taking CoQ10 ubiquinol (50mg with breakfast and 50mg with lunch), mitosynergy copper (split .5mg with breakfast and .5mg with lunch), black seed oil/curcumin (one capsule with breakfast, one with lunch). Lactoferrin (one capsule with breakfast, one with lunch), Jarrow reduced glutathione (one capsule before breakfast, one before bed), liposomal vitamin C (twice a day), creatine (4 split doses 3g total per day),

Elite IgG ImmunoLin blend for gut healing (one scoop before breakfast), ProButyrate (2 capsules before breakfast, two before dinner), and Hesperidin capsules (one capsule with breakfast to help with neuroinflammation).

From December 25th on I have been following the same protocol, with everything listed above, with the exception of adding Thiavite to my morning doses which adds all cofactors and increases TTFD by 15mg in the morning dose.

Reasoning Behind the Recent Supplements

I added the lactoferrin and black seed oil/curcumin as part of my Mitome protocol. When I did the Mitome test back in May 2025, it showed complex IV was at 24% and noted that I should be supplementing with heme iron, or if my ferritin levels were high that I should utilize whey protein/lactoferrin, with black seed oil and curcumin to lower inflammation so that trapped iron was released from ferritin.  It also noted that I should be using copper to support complex IV cytochrome C oxidase enzyme.  For the low complex II and II-III it noted coq10.  I’ve added all of these in, and hope that if what I’m also dealing with an addition to a thiamine deficiency, is also mitochondrial dysfunction, that this will help to support my mitochondria and correct all of the issues that I’m having. In recent lab tests my copper was on the low end of normal, but so was ceruloplasmin, with a free copper over 15.  In my iron labs, my iron was at the low end of normal, with transferrin below the normal range, and ferritin at the top of the normal range, with saturation at around 30%.

On December 31st, I did another 400mg of thiamine HCl intramuscular shots, and again the first day I felt more social and talkative, but since the 3rd I’ve been feeling very off. Migraines are back even worse, a sensation of extreme nervous system irritation and randomly losing hearing in my right ear. I feel like I still cannot get my electrolytes managed properly, and I’m left feeling like I’m never going to get back to my old self. My pulse was somewhat normalized in the morning before eating breakfast and at night, now it’s elevated again.

Where I Am Now

The last few days I’ve also had a lot of digestive upset. I’m getting more hives like reactions to all foods. Overall, I am very fatigued and feel like I’m walking through a dream. I don’t know how to continue supporting my body without causing more inflammation. I don’t know if this is all related to the B1 deficiency or if this is a much larger issue that I need to be working on.

I’m trying to walk around as much as possible so that my body will stimulate more mitochondrial biogenesis. I would to get to the point where I can drive again but my legs feel weak and I have very low energy levels. My doctors are pushing for me to do a stress test in one week, and if all goes well, they would like me to start physical therapy and occupational therapy. At this point, I feel like that is just going to make things worse, because every time I try to do anything physically or mentally taxing, I crash and then the next few days are miserable.

My time is also running out for being able to return to work. If I’m not able to return in the next 4 weeks, my position will be opened up. I’ve even tried to spend time with family, and simply holding a conversation causes the over stimulation reaction where I start to feel faint, my pulse rises, and my vision gets fuzzy, etc.

Please help me get my life back. I want nothing more than to return to work, spend time with family, and friends and help others who are in similar situations.

Post Script: I just learned that the IM thiamine shots I was prescribed contain 400 mcg/mL of aluminum each. I have been injected with a neurotoxin for months now. I have not been able to find a clean IM. If anyone knows of an IM thiamine without aluminum, please let me know.

Narcolepsy, Basal Ganglia, Mitochondrial Fitness, and Kickboxing

Published on

kickboxing, basal ganglia, narcolepsy

Several years ago, when I just beginning to understand the role of nutrient co-factors in mitochondrial health, I was working with a young woman who had been injured by Gardasil. She was my first ‘case’, contacting me online after a post I wrote about the thyroid damage done by this vaccine. Thyroid damage is among the more common disease processes initiated by many drugs and vaccines. It is one of the easiest problems to rule in or out, but more often than not, it is missed by most practitioners. Inasmuch as thyroid and mitochondrial function are reciprocally connected, where there is damage in one, there is damage in the other, and inasmuch as thiamine is requisite for healthy mitochondria, correcting thiamine deficiency can, in many cases, improve thyroid function. When I first met this woman, I did not yet fully appreciate that connection. Eventually, I would be introduced to Dr. Lonsdale and his work on thiamine deficiency, and so began my education. Together, we wrote a book about the role of thiamine deficiency in mitochondrial illness: Thiamine Deficiency Disease, Dysautonomia and High Calorie Malnutrition.

Exercise and Mitochondrial Healing

Her case is unique for a number of reasons, but mainly because, in addition to the thiamine and other nutrients required to heal, she used, and continues to use, exercise to manage her health. That is what I would like to talk about today: the role of exercise in mitochondrial health. Before we do that, below is a synopsis of her case, as reported in our book on pages 286-87. Her full story was provided on our website here.

In 2008, 26-year-old G.C., a previously healthy, athletic young woman, finishing a Master’s program in finance, received the three injections of the Gardasil vaccine. It bears mentioning that 2 years prior  she received several travel-related vaccines including diphtheria, typhoid, yellow fever, hepatitis A and B, the flu vaccine, and a tetanus boost and suffered no apparent ill effects.

After the second injection of Gardasil she experienced a flu-like episode with high fever lasting over a week. Full-blown hypersomnia manifested shortly thereafter and worsened to the point where she was able to sustain wakefulness for only 45 min to a maximum of 3 h per day. She experienced fatigue, muscle weakness, and dizziness. Over the next several months she developed tachycardia, intense salt cravings, with concurrent dizziness and thirst. The salt cravings led to blackouts and as she described “waves of extreme somnolence” that included slurred speech, lack of coordination, and imbalance. She learned to keep salt with her at all times. Both physical (e.g., walking, standing up, cooking) and mental exertion were profoundly draining. She reported that if she became angry or experienced any emotional event, she would immediately fall asleep. Multiple doctors had been seen and tests completed. By 2010, only low levels of vitamin D had been recognized.

Narcolepsy, Hypersomnia and Exercise

In late 2010, the fifth physician seen, it was diagnosed as narcolepsy without cataplexy–hypersomnia. She was prescribed 300 mg per day of Modiodal (Modafinil, Australia; Provigil, United States). Wakefulness increased, but she was still dizzy and required multiple hour naps after any exertion. She returned to working out. By the end of 2010 she began a PhD program and was determined to “power through.” She found that exercise, though difficult, allowed her to avoid blackouts. Of note, cardio-type workouts provided respite from the dizziness for 4–6 h, whereas weightlifting netted 24 h without dizziness. Similarly, she observed that if she ate simple sugars or carbohydrates the dizziness and blackouts would return.

Six months after beginning Modiodal her health continued to decline despite experiencing greater wakefulness. She developed severe noise and light sensitivity, continued to experience dizziness, and required excessive amounts of sleep, sea salt, and water. She developed a thick, dry, painful scale on her scalp. Another series of doctors could offer nothing and suggested the illness was in her head, inferring that she “needed to pull herself together.” Despite her health issues she defended her PhD in July 2013.

By October 2013 she had seen 10 physicians as her health continued to decline. She read our work on post-Gardasil thyroid dysfunction and other adverse reactions and requested additional testing. Hashimoto’s, hypogammaglobulinemia, vitamin B deficiencies, and low potassium levels were identified. On several occasions she attempted to get transketolase testing but was unsuccessful. In Nov. 2013 she decided to treat empirically beginning with 100 mg thiamine tetrahydrofurfuryl disulfide (TTFD). She subsequently developed the paradoxical reactions discussed in Chapter 4, with her symptoms worsening.

The Paradox or Refeeding Syndrome

With the dizziness and increased heart rate she reduced her dose to 50 mg of TTFD. Over the course of the next 5 weeks, the tachycardia landed her in hospital on four occasions. By December 2013 her body adjusted to the dosage of TTFD and the tachycardia and dizziness subsided. This is important to note. Long-term dysfunction of this nature requires new knowledge from the physician. Though not damaging to the patient it is regarded as “side effects” and either the patient or the physician stops the treatment. This effect was known to the ancient Chinese and regarded as examples of yin and yang by acupuncturists.

Over the course of the 5 years of progressively declining health she saw a total of 24 doctors. None of whom was able to identify or treat what was ultimately a metabolic disturbance brought on by thiamine deficiency that was likely triggered by the vaccine. Her final diagnoses included cerebral salt wasting, POTS, beriberi, hypersomnia, and Hashimoto’s. Arguably, the thiamine deficiency and the mitochondrial damage that ensued were at the root of each of these diagnoses.

Maintaining Health Post Gardasil

Since 2013 she has continued to maintain her health with thiamine, magnesium, and a cocktail of other mitochondrial supplements (which included very high doses of coenzyme Q10), along with thyroxine for Hashimoto’s and Modiodal to treat the somnolence. As of this writing she is doing well, training in various Asian forms of kickboxing daily and working full time. Without the balance of heavy training, the cocktail of supplements, the Modiodal, and thyroxine, her symptoms reappear.

Her case is remarkable for a number of reasons. First, that she recovered at all is impressive. Many women injured by Gardasil do not recover. She did and continues to thrive all of these years later. Her recovery was not linear though and her continued health requires aggressive attention. I think this process throws many people. We have been trained to expect that recovery from illness proceeds in a logical, linear, and expeditious manner. It does not. There were many setbacks, including several hospitalizations when she first began supplementing with thiamine. Had she not persisted through these setbacks, she might not have recovered her health. Moreover, had she not recognized the fragility of this recovery and continued to actively manage her health all of these years later, she could have easily become seriously ill again. kickboxing, basal ganglia, narcolepsyIndeed, there have been many relapses over the years, where her health declines significantly and requires extended periods of recovery. Nevertheless, she is able to recover and that is remarkable.

Secondly, and what I think is particularly unique about her case, is the role that exercise has played in her ability to recover and maintain her health. It is not something that conventional or even functional medicine gives much credence too. Sure, we all recognize the role of exercise in health generally, but mostly, we ignore it. I think this is a mistake. In her case, exercise was and remains critical to maintaining her mitochondrial health and as I have come to understand recently, the type of exercise that she gravitated towards naturally, kickboxing, may be exactly what her brain needs to function.

The Role of Exercise in Recovery

From the beginning of her illness, she forced herself to exercise, even though it was an immense struggle. On her own, she learned that certain types of exercise would prevent her dizziness and blackouts. Specifically, if she did cardio-type exercise, she could prevent a blackout for 6 hours or so, but if she added some weightlifting, the effects would last for up to 24 hours. I attributed this to exercise-induced mitochondrial biogenesis. That is, exercise was forcing the birth of new mitochondria, and somehow, shifting her balance of unhealthy to healthy mitochondria more favorably. It was also likely improving the respiratory capacity of her existing mitochondria. Although it is still not clear to me why one modality yielded better results than another, as the research in this area seems to suggest that the opposite is true, that cardio yields more mitochondrial benefits than weightlifting, the research is clear that exercise induces both mitochondrial biogenesis while improving their functionality.

Her seemingly innate realization of this was and remains one of the more noteworthy aspects of her case. Remember, for several years after Gardasil vaccine, she was seriously ill. When she first contacted me, she weighed less than 100 lbs, was severely fatigued, and could not maintain wakefulness for more than a few hours at a time without blacking out; and yet, somehow, she managed to drag herself to a gym to exercise (and maintain her graduate work in finance). Not only that, she observed a pattern of response to exercise (and salt and other dietary components) and used what she learned to help herself function better. Indeed, throughout her recovery, she would actively observe the patterns and optimize those that appeared beneficial and eliminate those that did not; something that we all should be doing as a matter of course, and yet, very few of us do.

To exercise throughout an illness where intractable fatigue, excessive somnolence and blackouts dominate is very difficult to do, and more often than not, would be discouraged. When I first wrote about her using exercise to heal, the backlash was immediate and intense. For her though, the exercise became an integral component of maintaining her health just as surely as the nutrient elements. Even now, 12 years from initial vaccine-induced illness and with 7 years of recovery under her belt, she indicates that when she misses training because of work or travel, her health declines rapidly and does so in a fairly specific manner. She becomes dizzy, loses balance, and her cognitive capacity diminishes significantly. Her ability to maintain wakefulness declines while fatigue increases. Additionally, when the stress of normal everyday illnesses come into play, a viral infection for example, and her exercise program naturally takes a hit, in order to fully recover she has to double-down on the training for a period of time once the illness passes.

Is this need to exercise unique to her case specifically or could we learn something about how we approach recovery from illness? I would argue that given the mitochondrial fitness attributable to exercise and the noted mitochondrial decline in its absence, some form of movement or exercise should be approached with any recovery plan. If this is the case, the questions become, at what point in the illness or recovery should exercise be considered, how much, and in what form? While the answers to these questions are far too individual to explore fully here, what we learn from her case is that exercise, when implemented early, improves recovery. That brings us to a more complicated question; why kickboxing, boxing, or other dynamically challenging programs might be useful for narcolepsy specifically. From what I have learned, it may be related to activating and training neural connections in a region of the brain called the basal ganglia. And of course, the mitochondria are still involved.

Enter Kickboxing and the Basal Ganglia

I believe there is damage to the basal ganglia for her and other Gardasil injured women. To this point, among the more common symptoms associated with Gardasil injury are tremors, ataxia, and gait issues. While those symptoms can easily be attributed to cerebellar and thyroid damage as well, and both of which are affected by the vaccine and thiamine deficiency, it is not without warrant that we look at the basal ganglia for these symptoms, as well as for the sleep and wakefulness issues. Neural tracts between the cerebellum and basal ganglia suggest that if one is damaged, messaging and functioning to the other would be impaired. Indeed, research shows both efferent and afferent disynaptic (from and too, two neuron) connections between the cerebellum and the basal ganglia. Additionally, personal communications with other women affected by Gardasil regarding imaging results confirm damage to the basal ganglia in some women. This is in addition to potential cerebellar damage.

Symptomatically, many post-Gardasil women display an ataxic, drunken sailor like gait, which is indicative of cerebellar involvement while their tremors occur at rest, along with muscle rigidity and dystonia, indicating basal ganglia involvement. All of them suffer from what could be termed hypersomnia and excessive fatigue, but none that I have met thus far were diagnosed with narcolepsy, like this patient. Of course, that does not exclude the possibility that it does not exist. The post vaccination symptoms are diverse as one might expect with mitochondrial damage and autonomic system dysfunction.

Why the Basal Ganglia?

The basal ganglia are set of nuclei buried deep in the brain that are responsible for controlling movement, motor learning, executive function (via connections with the frontal cortex) and emotional regulation and motivation (via connection to the limbic system). See figure 1.

brainstem basal ganglia
Figure 1. Tracts of the basal ganglia.

The basal ganglia act as a breaking system to complex movement patterns and activities.

The most well known disorders of these nuclei include Parkinson’s and Huntington’s diseases. These are dis-inhibition syndromes, where the normal inhibitory control that the basal ganglia hold over motor movements is lost resulting in tremors and chorea respectively. There are also problems with initiating movement. This occurs via connections to the limbic system, particularly a set of nuclei located in what is called the ventral tegmental area (VTA). These nuclei are central to motivating behavior, addictive behavior in many cases, but also, behavior in general. The dopamine released by the VTA neurons provide reward and reward, as we all know, encourages habit and learning. That hit of dopamine gives us the drive to act. As Parkinson’s disease progresses, patients lose these connections and with them that internal, unconscious motivation that initiates behavior. They become stuck and so absent an external cue, patients will become unable initiate a movement internally on their own. This stuckness might sometimes also manifests as a sort of depression; one where there is no motivation to act at all.

One of the latest alternative treatment modalities for Parkinson’s disease, aside from thiamine, involves boxing. Yes, boxing. Boxing, because of the balance requirements, the bilateral, stop/go and cognitively active nature of the exercise seems to activate tracts in the basal ganglia that increase inhibitory control, reduce tremors, and allow for a smoother initiation of movement patterns. It also improves gait speed and balance, conditioning, cognitive ability, and overall quality of life.

What does all of this have to do with the ability to maintain wakefulness, and as our patient indicated, cognitive clarity? This, as far as I can tell, has not been studied, but I suspect it has to do with enhancing motivation. Not motivation in the psychobabble sense, but motivation as a fundamentally physiological, survival-based behavior; motivation that is controlled by the basal ganglia via connections to the limbic system and the frontal cortex, respectively. That hit of dopamine that engenders motivation is key for not only movement but arousal. When there is damage to that system, wakefulness is near impossible. Rodent studies have born this out. Without ‘motivation’ we cannot remain awake and we cannot sustain the arousal necessary for mental acuity.

Consider for a moment, the key aspect among all of the behaviors controlled by basal ganglia is that they necessitate wakefulness. Given that, it makes sense from a purely logical perspective that the basal ganglia might be involved in maintaining the arousal necessary to perform these activities. Similarly, it makes sense that damage to certain tracts within these nuclei could impair not only one’s ability to maintain wakefulness, but also, one’s ability to manage motor movement with altered sleep/wakefulness patterns. Finally, absent sustained and vigilant wakefulness, mental acuity is impossible. The cognitive fogginess, so often reported by these patients, may very well be linked to disruptions in basal ganglia functioning.

But Wait, There is More: The Orexin System and the Basal Ganglia

When narcolepsy and other sleep/wake disorders are researched, the basal ganglia have only recently come into view. This is despite the fact that the most well-known disorders of the basal ganglia, like Parkinson’s, demonstrate clear sleep/wake disturbances. Instead, another set of neurons located in the hypothalamus, called the orexin/hypocretin neurons (same neurons, different name), dominate the research landscape. Damage to these neurons is clearly linked to narcolepsy, cataplexy and other sleep/wake disturbances, and for our purposes, directly attributable vaccine reactions, especially the flu vaccine. The basal ganglia, not so much. How do we reconcile the known connections between orexin system, narcolepsy, and vaccine damage, the paucity of research on the basal ganglia. Well, like everything in the brain and body, we look for communication patterns. And it just so happens, the orexin neurons clearly interact with the basal ganglia to manage arousal, both directly via orexin receptors in various regions of the basal ganglia and indirectly, via vast projections throughout the limbic system, which then project to the basal ganglia.

Backing up just a bit, the release of orexin induces wakefulness. I have written about this system here, here, here, and here. When orexin neurons are turned on and firing appropriately, arousal is maintained. When orexin neurons are turned off, diminished or dysfunctional, melatonin, the sleep promoting hormone, is turned on. The two work in concert to manage wakefulness and sleep. Orexin receptors are located throughout the central nervous system and in the body. For our purposes, the orexin receptors in the amygdala and throughout the limbic system directly activate the release of dopamine from the VTA. Recall, dopamine projections from the VTA to the basal ganglia are critical for motivating and sustaining wakefulness in Parkinson’s patients. Additionally, orexin receptors have been found in different regions of the basal ganglia themselves, suggesting direct regulation of arousal. Perhaps even more importantly, the orexin neurons have been found to be instrumental in integrating motor movement patterns.

“…numerous neuroanatomical and immunohistochemical studies reveal that essential subcortical motor structures, such as the basal ganglia, cerebellum, and vestibular nucleus, receive direct innervation from orexin neurons. Moreover, during movements, orexinergic neurons are particularly active and orexin release increases. The evidence suggests that the orexinergic system directly participates in central motor control.”

So what we have is an integrated system of arousal, movement control, and cognitive behaviors that relies heavily on the health and functioning of the basal ganglia and its connections through out the brain, including with orexin system in the hypothalamus. And the orexin system itself relies heavily on functioning mitochondria, as does everything, but the orexin neurons are particularly sensitive to diminished mitochondrial function as these neurons require as much as 5-6X the amount of intracellular ATP to maintain firing compared to other neurons. The orexin neurons cease firing when ATP stores become low, inducing sleep to allow the reallocation energy towards more basic survival functions like heart rate and respiration. That means that excessive sleep is to be expected with mitochondrial damage.

Putting It All Together

With direct stress to the mitochondria via vaccines and medications we can expect  a variety of negative symptoms. In this case, our patient developed thyroid damage, autonomic dysfunction (cerebellar and brainstem involvement), and likely also, some degree of basal ganglia injury. The hypersomnia, so commonly experienced during illness or adverse medication/vaccine reactions, represents diminished orexin activity likely initiated by diminished mitochondrial capacity. Narcolepsy suggests a specific injury to oxexin system. With the diminished orexin capacity, we can anticipate that basal ganglia function would be impacted, and with it, the ability to maintain the requisite ‘motivation’ for arousal and wakefulness and to coordinate movement and maintain cognitive acuity. Nutrients and exercise improve the respiratory capacity of mitochondria, which in turn, provides the requisite energy to manage autonomic function from the brainstem and cerebellum and to sustain wakefulness by maintaining orexin firing in general and to the basal ganglia more specifically. Additionally, exercise that demands dynamic, bilateral, complex movement patterns, such as kickboxing, may serve to retrain or maintain the strength of synaptic connections to, through, and from the basal ganglia, which ultimately, may offset any damage done by the initial insult.

Let Food Be Medicine

At the risk of repeating myself too much as in former pages of this website, I want to return to discussing in some depth the fallacies incorporated in our present approach to health and disease. You may or may not remember that I have stated a number of times that Hippocrates (400 BCE) uttered the formula “Let food be thy medicine and medicine thy food”. Having been construed as the “father of modern medicine”, it has seemed to me for a long time that he has been ignored as a “parent”.

For centuries, there was no idea about disease. The early Egyptians bored holes in people’s heads “to let out the evil spirits”. Throughout medieval history the only treatment seems to have been “bloodletting”. In our modern world, horns from the rhinoceros are regarded so highly for their medical properties, that this wonderful animal is reaching the point of annihilation. Pharmaceutical drugs, with the exception of antibiotics, only treat symptoms. I ask you, does this make any sense at all in the light of what Hippocrates suggested?

Because humanity tends to follow a collective pattern and only rarely listens to an idea derived from rational deduction, I view medicine as like a traveler on a road without a known destination. In my imagination, he comes to a fork in the road, but the signpost records information on only one fork. It reads “kill the enemy”, reminding me of the story of Semmelweiss, a lone thinker in his time and who “gave thought to the message on the signpost”. Most physicians are familiar with this story but it is worth repeating.

Semmelweiss was a physician who lived at a time before microorganisms had been discovered. He presided over an obstetric ward where there were 10 beds on one side and 10 beds on the other. The physicians would deliver their patients without changing their clothes or washing their hands. As we would expect today, the death rate from infection was extremely high. Semmelweiss said to himself, “they must be bringing [the enemy] in on their hands” and he devised the first known clinical experiment. He made it a rule for the physicians on one side of the ward to wash their hands in chlorinated lime before they delivered their patient. The physicians on the other side of the ward continued to deliver their patients in the same old way. As we would easily recognize today, it did not require a statistician to see the difference between the incidences of infections on the two sides of the ward. Irrespective of the fact that this was a dramatic discovery that later had obvious meaning, Semmelweiss was accused by the medical authorities of the day of being non-scientific because he could not explain what it was that was supposed to be on the hands of the physicians. Of course the medical establishment had no idea that their model for disease was catastrophically wrong, although collectively certain that their philosophy bore all the hallmarks of scientific truth. Semmelweiss had offended the medical establishment and they threw him out of the hospital. He died a pauper in a mental hospital.

The First Medical Paradigm: Kill the Enemy

When microorganisms were discovered to be responsible for infections, it fulfilled the message on the signpost and it became the first paradigm in medicine. Kill the bacteria: kill the virus: kill the cancer cell, but try not to kill the patient. If we look at the history of this time, we find that a lot of patients were killed in the concerted attempts to find ways and means of killing the enemy. We all remember the discovery of penicillin and how it led to the antibiotic era, still the major therapeutic methodology, even though we know that it is running into bacterial resistance and has never been a good idea for viruses or cancer cells.

Although the germ theory had been around for a long time, Louis Pasteur, Ferdinand Cohn and Robert Koch were able to prove it and are regarded as the founders of microbiology. However, Pasteur was said to have uttered the words on his deathbed “I was wrong: the microbe (germ) is nothing. The terrain (the interior of the human body) is everything”. Perhaps he had unknowingly voiced the principles of the next paradigm in medicine.

The Second Medical Paradigm: Genetic Determinism

The monk, Mendel, by his work on the segregation of peas, formulated what came to be known as the genetic mechanisms of Mendelian inheritance and the discovery of DNA modeled the next stage in our collective development. The fact that each of us is built from a complex code that dictates who we are was a remarkable advance. The fact that the construction of the code sometimes contained mistakes (mutations) led us to explaining many diseases and for a long time we believed that the genes were fixed entities, dictating their inexorable commands throughout life. However, the newest science of epigenetics has shown us that the DNA that makes up our genes can sometimes be manipulated by nutrition and lifestyle, as well as by artificial means in the laboratory.

Health: The Ability to Respond Effectively to a Hostile Environment

We are surrounded by germs that exist everywhere, many of which cause disease as we are all too well aware. Nevertheless, whatever evolutionary mystery guides our development, we are all equipped with an extraordinarily complex, genetically determined, defense system. We now know that this is organized and directed by the brain. Assuming that the genetic determinations of the terrain are completely intact, we can be reasonably assured that we can defend ourselves from any germ that Mother Nature can throw at us. Built in mechanisms in the brain require a huge amount of energy when it goes into action directing the traffic of the immune system. It is a crisis and can be likened to a war between the body and the attacking organisms. Thus, if Pasteur may have stated the next paradigm in medicine, what does it mean?

As an example, a typical microbial attack causes a common disease that goes by the name of febrile lymphadenopathy (strep throat). The throat becomes inflamed, perhaps because the increased blood supply brings in white blood cells, acting in defense. An increase in circulating white cells also occurs, bringing a brigade of defensive soldiers. The glands in the neck become swollen because they catch the germs that get into the lymph system.  Lastly, the increased temperature of the body is also part of the defense. Germs are programmed to have their most intense virulence at 37°C, the normal body temperature. If this temperature is increased, the attacking germ does not have its maximum efficiency. In other words, what we are looking at as the illness is really the act of brain/body defensive interaction. Besides attempting to kill the attacking germ as safely as possible, should we not be assisting the defense? The answer calls into question the relationship between genetic intactness and the required energy to drive the complex defensive action. Perhaps a genetic mistake (mutation) can sometimes be manipulated by an epigenetic approach through nutrients, just as advised by Hippocrates.

Disease: The Inability to Adapt to the Environment

If we look at health as the ability to respond effectively and adapt to environmental, mental and physical stressors, it is possible to re-conceptualize illness by the manner in which that response is carried out. A healthy individual will respond to stressors without problem, because of an efficiently effective mobilization of energy dependent mechanisms. In contrast, individuals who are not healthy will respond in one of two ways. Either the defense mechanisms will be incomplete or absent or over-reactive and inconsistent. Listed below are examples of both. Note that this is in line with the ancient philosophy of Yin and Yang or, in modern terms “everything in moderation”. Too much of anything is as bad as too little.

Exhausted Defense Systems

When I was a resident in my English teaching hospital, before the antibiotic era, I admitted a patient with pneumonia who was known to have chronic tuberculosis. He was seen to be “unconsciously picking at thin air with his fingers” and the physician for whom I was resident pointed out that it was a classic example of “a sick brain” and that he would die. He never had any fever, elevation of white blood cells or any other marker of an infection but at autopsy, his body was riddled with small staphylococcal abscesses. He had lived in the east end of London, notorious for poverty and malnutrition at that time. In fact, as an organism, he never showed the slightest sign of a defense. His “sick brain” was completely disabled in any attempt to organize his defense.

Excessive or Aberrant Defense Mechanisms

Many years ago I was confronted with two six-year-old unrelated boys who for several years had each experienced repeated episodes of febrile lymphadenopathy. Both boys had been treated elsewhere as episodes of infection. In each case the swollen glands in the neck were enormous. One of the boys had been admitted to a hospital for a gland to be removed surgically for study. It had been found that the gland was just enlarged but had a perfectly normal anatomy, only contributing to the mystery. One of the curious parts of the history was that each of these boys had been indulged with sweets. Because I was well aware that sweet indulgence could induce vitamin B1 (thiamine) deficiency, I tested them and found that both were indeed deficient in this vitamin. Treatment with large doses of thiamine completely prevented any further attacks. The mothers of the boys were advised to prohibit their sweet indulgence. I needed some evidence and asked one of the mothers to stop giving thiamine to her son. Three weeks later he experienced a nightmare, sleep walking and another episode of lymphadenopathy that quickly resolved with thiamine.  A nightmare and sleep walking supported the contention that the brain was involved in the action. In addition, his recurrent illnesses had been associated with increased concentrations of two B vitamins, folate and B12, both of which decreased into the acceptably normal range with thiamine treatment. Of course, this added complexity to an explanation.

What I had already learned about thiamine deficiency is that it makes the part of the brain that controls automatic mechanisms much more sensitive. One or more reflexes are activated unnecessarily. No reflex activation is as bad as too much. Thus, the “trigger-happy” defense mechanisms were being activated falsely. Thiamine is perhaps the most important chemical compound derived from diet that presides over the intricacies of energy metabolism. All that was required was an improved energy input to the brain. Folate and B12 are vitamins that work in energy consuming mechanisms and I hypothesized that their respective functions were stalled for lack of energy, causing their accumulation in the blood. Whatever the explanation, the facts were as described. It is interesting that the high levels of folate and B12 had been found at the hospital where a lymph node had been removed. The mother had been accused of giving too many vitamins to her child. She had told me that she did not understand this explanation because she had not given any vitamins to him. I had measured them solely to verify this finding.

The Treatment of Disease Should Begin with Host Defenses

We exist in a hostile environment. Each day throughout life we live in anticipation of potential attack. A physical attack may be an injury, an infection or an ingested toxin. A mental attack, divorce, grieving, loneliness, generally referred to as “stress” may be virtually anything that causes the brain to go into increased action. In facing both physical and mental forces, it is the brain that organizes the defense and it demands an increase in energy output that depends solely on the ability to burn fuel. The fuel burning process is governed by a combination of genetically determined ability and the nature of the fuel. Thus, the treatment of all disease is dependent on this combination being effective. It can be seen as obvious that killing the enemy is insufficient. As our culture exists at the present time, trying to get people to understand the necessity of perfect nutrition is a pipe dream. This particularly applies to youth and the artificiality of the food industry. However, our culture is also virtually brainwashed to accept tablets as a means of treating anything.

In our recently published book “Thiamine Deficiency, Dysautonomia and High Calorie Malnutrition“, Dr. Marrs and I have shown that thiamine deficiency is extraordinarily common and that supplementary thiamine and magnesium together balance the ratio of empty calories to the required concentration of cofactors necessary for their oxidation. The question remains, would vitamin supplementation, just as artificial, be a more successful sell as a preventive measure? We have shown that the symptoms derived from prolonged high calorie malnutrition can last for years as an unrecognized polysymptomatic illness that haunts many physicians’ offices. Early recognition represents an easy cure. There is a good deal of evidence that ignoring the symptoms and the persistence of high calorie malnutrition creates a gradual deterioration that then turns up as chronic disease. Some drugs, metronidazole being an example, will precipitate thiamine deficiency, so we have to recognize the precarious nature of the present medical approach in the use of drugs whose action in treating disease is often unknown. Although recognition of the artificiality of thiamine supplementation is implicit in this proposal, it is better than allowing a common example of continued morbidity to exist.

Elimination Dieting and Progressive Thiamine Deficiency

Published on
6.7K views
Elimination diet

My issues began after the birth of my second child 21 years ago. I would get extreme indigestion for a couple days each month and my skin broke out. This continued for years until I ended up having several rounds of antibiotics. Months later, I developed severe and never ending acid reflux. After struggling for a year, my local health food store owner mentioned the blood type diet and recommended I avoid dairy. The result was magic. Unfortunately, this started a cascade of elimination diets that would set the tone for the next fifteen years.

After eliminating dairy and seeing a resolution of symptoms, at least temporarily, I decided to eliminate gluten too. As with the dairy, the indigestion disappeared temporarily when I eliminated gluten, but other symptoms eventually crept in, including hypothyroidism and bile reflux. I read about a vegetarian diet and decided to give it a try. Again amazing results from removing meat. The bile reflux disappeared.  I thought things were going pretty well, but in these years I started to have other issues: ataxia, fatigue, heat intolerance, numbness and tingling, gait and bladder issues. In addition, I was always starving. I ate a tremendous amount of food each day, but at the same time I was losing weight.

My naturopath had mentioned possible problems with my gallbladder, but I didn’t think too much about it until I had constant pain. It was eventually discovered that I had a non-functioning gallbladder and I reluctantly had it removed, hoping it would solve my problems. I had tried changing my diet to the autoimmune paleo several times, but would always crash after a couple weeks. After surgery, I could eat meat without major issues, but nothing seemed to digest well. I felt like I never really recovered and other issues started to creep in.

My calf muscles would spasm upon standing and I was so weak I was having difficulty walking a block. A year after surgery, I was diagnosed with primary progressive multiple sclerosis, as it matched my symptoms and lesions were seen on my cerebellum and down my spine. The hallmark of PPMS is neurodegeneration without inflammation. The next three and a half years were a quick decline. I quickly became unable to walk unaided, mainly because I was too fatigued and my muscles too weak. PPMS used to be called creeping paralysis and that is exactly what was happening; I was unable to move my arms or legs, my equilibrium was so off that I couldn’t stand without tipping over and I couldn’t look down to even zip up my jacket.

I had really bad edema in my lower legs and feet and they were a nice shade of purple. My brain was easily overwhelmed and not committing things to memory, which left me going in circles. I lost my appetite, but blamed it on my ever changing diet and my fear of eating the wrong food. I would alternate between diets, cutting various food groups with very limited success.

I visited multiple naturopaths, a functional medical doctor, a NUCCA chiropractor and a MS specialist. I have researched endlessly and have a cupboard full of supplements. I had tried B vitamins before but had not noticed a difference. I joined a Facebook group called Understanding Mitochondrial Nutrients and did not think much about the vitamin I needed most, thiamine, until a post by a desperate husband came up in my feed. I began to research thiamine and found I was able to piece together a timeline of my life based on a progressing thiamine deficiency. I am only three weeks into dosing with thiamine (I take 200mg thiamine HCL and 240mg benfotiamine) and a B complex, but it has made such a difference in my balance, fatigue, edema and mental energy. My appetite is back and I can zip up my coat! I am cautiously optimistic, only because I have suffered so much disappointment in the past. I am hopeful that I can make a recovery.

My Decade of 24/7 Depression

Published on
7.9K views

I am a 60 year old female who has been experiencing severe depression with anhedonia for over a decade. I often feel oxygen and energy deprivation in my head more often when I lie down. I have a lot of short term memory problems and executive functioning issues that began around age 50. Sometimes I feel the earth move under my feet and I am occasionally dizzy and have double vision. If I look intently at things, it appears as though they are moving. I also have some visual tracking issues. This is partly do being blind focally in one eye and floaters in both, but I suspect there is more too it. I have endured restless leg syndrome for years, which has been significantly less for the last few weeks after beginning thiamine, as have some of my other symptoms, but the depression, anhedonia and general loss of motivation and lack of joy remains. I have begun using a variety of supplements but feel as though I am still missing something. I am sharing my story in the hopes that someone can offer some help.

Childhood Through Early Adulthood

Since childhood, I have felt physically crappy. I was never able to breathe through my nose. I had asthma and constant, intense itching in my ears, nose, throat, head, and eyes. Insomnia plagued me as a child due to anxiety, along with the inability to breathe and the intense itching in my head. Regularly, and especially at night, I fantasized of putting an icepick into my ear to scratch the horrible itch in the center of my head. All day, everyday, I choked on the constant snot that continuously poured out of my nose and clogged my throat. I choked often on my food being a total mouth breather. I needed a box of Kleenex’s to get through a day. Despite it constantly running, I could not breathe through my nose at all. Encumbering as all this was, I still managed to feel somewhat hopeful, played outdoors, had friends, and attended school most days.

I chose to leave home quite young (at 15 years old) because of family dysfunction. By 16, I stopped consuming liquid dairy, thus leading to a nose-breathing liberation. I still was plagued with sinus issues but could breathe occasionally through my nose to some degree for the first time ever.

As a youth, I experimented with drugs, but never really took anything regularly as the hangovers were horrible and weakening for me. I did a fair amount of drinking in twenties as well but paid the price health wise, and since have not had a drink in many years.

In my twenties, I became aware of sugar causing severe hypoglycemia in me, caused huge mood swings and vision loss. I also self-diagnosed myself with hypothyroidism. I went to see doctors assuming this was causing my miscarriages but the doctors invalidated me at every turn, insisting I was fine. So my Hashimoto’s went untreated for many years until I discovered I could treat it with over-the-counter desiccated thyroid.

Even with all of this going on, I just kept dragging myself along through life on what felt like sheer willpower alone. During this time (my 20’s), I ate more vegetables (fresh organic) and less meat, I had a lot of stomach pain that plagued me on top of everything else, even though my diet was quite good and full of organic vegetables grown nearby. I wasn’t a trying to be a vegetarian, I always thought of myself a bit more of a carnivore, but being that I lived among vegetarians I didn’t eat meat on a daily basis. I noticed that when I did eat meat, I felt a little better. I wish I had taken it more seriously then, but I was still in my optimistic youth, and every day was a new day where I thought I was going to magically feel better.

Lifelong Anxiety and Stage Fright

Prior to the depression, I was a violinist, but one who suffered from lifelong, crippling stage fright. As a child I couldn’t sleep at all for days prior to an audition or performance, which was often. This continued my whole life. Nevertheless, I was able to push through and have performed and recorded many pieces with many different people through the years. Over time though, I began to avoid auditions, and mostly, only performed solo for strangers like at weddings and parties where there weren’t high expectations. Many times, I convinced myself to get over this anxiety, I just had to do it, to get out there and perform. This never worked. I never got over it. Oddly enough, no one realized what I was going through while I played.

I took immediate release Adderall 40-60mg 2-4 x a week for about 5 years in my late 40s to early 50s. It was prescribed for ADHD and for stage fright during violin performances. It also helped with motivation. I have always had a pretty scattered ADHD type personality and felt that I was a high functioning autistic person.

I take trazodone to help sleep when I can afford to get it, but it doesn’t always work. So lately I have been taking a break. Sometimes I will take an over the counter antihistamine/cold medicine like Tylenol when I am desperate to sleep, like when I’m caring for mother. It is a last resort though. I prefer not take anything being it makes me a little nauseous and I worry about liver damage.

I tried Wellbutrin for depression for several months about a year and a half ago, but felt nothing. I tried Prozac for four weeks in my 40s and also felt nothing.

Mumps and Loss of Vision in One Eye

I got the mumps in my forties. This was the closest I ever felt to death in my life. I subsequently lost vision in my right eye. When I lost my vision, it was assumed that I had ocular histoplasmosis but a few years prior to that I had lost vision in one eye for a few months to an unusual eye condition called MEWDS, (multiple evanescent white dot syndrome). MEWDS can be induced by a virus, perhaps having the mumps virus had something to do with it. I also wonder if I was actually type 2 diabetic off and on in my life, or at least borderline, and if that cost me my eye.

Debilitating Depression

After a lifetime of feeling crappy, multiple miscarriages, carpal tunnel, loss of vision in one eye, foot, back, and joint pains, continuous often intense neck pain that has been there since my twenties, along with severe insomnia and allergies, I arrived at 50 years old and began a quick descent into an abyss of deep and unexpected depression and anhedonia. I have been stuck here and have wanted to die 24/7 for 10 years, but haven’t because I do not want to hurt my grown son, and I am sharing the out of state caretaking of my mother and stepfather with dementia with my brother. I have been desperately trying for the last decade to recover my health. To that end, I have taken many supplements but none have really noticeably worked.

Attempts to Recover

Seven years ago, I took to injecting B12 after self-diagnosed pernicious anemia, but never felt a noticeable difference. I was extremely fatigued. I also injected a B complex regularly for several weeks or more without noticing a difference. I still feel a lot of fatigue but with the loss of motivation I think it is possibly more mental than physical.

Ten months ago, I began a strictly carnivore diet. Carnivore has helped inflammation. My bowels are way better and my lifelong mouth ulcers stopped immediately. There have been many other small wins. Unfortunately though, it means  next to nothing to me because it has not fixed my depression, my enjoyment, or will to live. These are the core symptoms that I need to fix. I don’t understand why others get over their depression and insomnia and I cannot seem too. I also still loose lots of hair, but this has been going on for about 7 years. This is traumatic for me (constantly).

About three months ago, I experienced tachycardia plus dizzy spells for several days. The doctors said my iron was fine but I upped my heme iron and b12 and I think it helped. I eat a lot of liver/meat so it surprises me that I would ever be low in b12 or iron. I still feel a little floaty at times, but my heart rates are more normalized.

Recently, I discovered the literature and videos on high dose thiamine. I was very excited, and finally, once again hopeful.

I have taken both TTFD and benfotiamine for a couple weeks now and am not really noticing any changes paradoxically or feeling better. I recently added the HCL too. I have tried upping my doses significantly to where I was taking over 2000mg of Benfotiamine, 400mmg of TTFD and 400mg of thiamine HCL for several weeks. But I have since lowered it considerably. I also take magnesium (100mg), glutathione, riboflavin (100mg) the other B vitamins via yeast, B12 with intrinsic factor (500mg), and electrolytes, and I eat head to tail carnivore including bone broth. I take a substantial amount of more than 400mg of desiccated thyroid as well for the Hashimoto’s disease.

I started taking high dose niacin, perhaps a week ago and I think it kind of helped the thiamine. I felt a certain weight in my head lessen. It was not so much emotionally noticeable but like a bunch of swelling must have loosened. Then two nights ago, my body, legs, and some in arms, swelled up horribly. It was very itchy, painful and lumpy; like I had gained 20 pounds overnight. I haven’t had a history of noticeable edema. This scared me and I decided it was lymphedema, so I began doing lymph draining exercises. I finally felt it was not expanding any longer and perhaps even subsiding a day and half later. I felt hopeful that the brain inflammation FINALLY made a breakthrough, and my body was dealing with the toxicity that had been stuck in there, but I’m not sure what caused the sudden swelling. I also noticed during the swelling that I was urinating less, no matter my fluid intake. Perhaps my body was trying to dilute the toxicity and thus the necessary accumulation. I didn’t take the niacin or thiamine for the next two days. Then yesterday, I took a 1 gram niacin dose and felt a decline in the swelling, and later, around 3 am, I took another niacin, which somehow helped my body hurt less and I could relax. Now a few weeks later, the swelling has decreased considerably. I think it’s going to take some time to feel the results of brain regeneration and habitual behavior, but I don’t feel that feeling of a huge lump of coal stuck in my head anymore. I am currently taking 300mg of benfotiamine, 100 thiamine HCL and 100 allithiamine along with my minerals, electrolytes and vitamins. I also added oregano oil protocol that I heard could help with Hashimoto’s.

Please Help

I used to be highly creative and performed violin for a living, whereas now I cannot find any hope or inspiration to play or do anything and haven’t in years. I desperately want to clear the fog from my brain and regain my will. It is as if I am overwhelmed and underwhelmed at that same time. It is difficult to describe, except that I am miserable. What am I missing? Please any advice appreciated. Thank you!

Childhood Trauma, Diet, and Behavior

Adverse Childhood Experiences and the Diet Variable

Nearly one in eight children (12%) are reported to have had three or more negative life experiences associated with levels of stress that can harm their health and development. In 2011, nearly 60% of children age 17 and younger were exposed to violence within the year, either directly as victims or indirectly as witnesses. Twenty-one per cent of children in the United States suffer from mild behavioral health problems and an additional 11% struggle to overcome significant behavioral health, according to the Adverse Childhood Experiences study. This estimate translates into a total of 4 million youth who suffer from major mental illness (US Department of Health and Human Services 1999, 123-124). An estimated 26% of Americans aged 18 and older (about one in four or over 57 million adults) suffer from a diagnosable mental disorder in a given year.

As if this were not enough, the Children’s Crisis Treatment Center in Philadelphia indicated that “in 2011, 29% of students in grades 9 through 12 reported feeling sad or hopeless almost every day for two or more weeks in a row in a year. Up to 70% of children and teenagers in the juvenile justice system have a diagnosable mental health disorder and up to 44% of high school students suffering from behavioral health issues drop out of school”.  If these statistics are accurate, they are deplorable.

Malnutrition as a Major Cause of Brain Disease

With these huge numbers involved, of many potentially causative issues, there is considerable evidence that bad nutrition may dominate them. It is interesting that, many years ago, a Probation Officer in Cuyahoga Falls in Ohio persuaded a judge to hand over to her care all the juvenile criminals that stood trial in his court. She regulated their diet and supervised it. The recidivism (habitual lapsing back into crime) dropped to almost zero. Unfortunately, good nutrition is commonly overcome by hedonism (love of pleasure) and is usually governed by the sweet taste. There are two aspects to this. Sugar in all its different forms precipitates thiamine deficiency and the signal from the tongue to the brain is responsible for its addictive qualities. There is little doubt that thiamine deficiency is heavily responsible for much of the mental disease that is so commonly represented in our culture. It is especially damaging to the lower part of the brain that governs our emotional responses and our ability to adapt to a hostile environment. Because thiamine deficiency produces an effect similar to that of oxygen deficiency (hypoxia) it has been seen as a cause of pseudo-hypoxia (false hypoxia). Either true or false hypoxia is interpreted by the brain as a potentially dangerous threat to the organism.

Some years ago I had the opportunity to visit the Philadelphia Crisis Treatment Center that then existed under another name. I learned of a neurosurgeon who had been deeply involved with its original inception. He had suggested that seizures (epilepsy) were caused by a deficiency of oxygen (hypoxia) in the brain, perhaps explaining the usual resistance of juvenile seizures to drug treatment. Although the statistics above did not specify the nature of “major mental illness” in 4 million youths, I pondered over the years whether hypoxia or any part of its equivalent mechanisms (pseudo-hypoxia) could be the underlying cause common to brain disease in a variety of different expressions, including even epilepsy in some cases.

After my visit to Philadelphia, I had an opportunity to test the neurosurgeon’s suggestion by treating a 12-year-old boy in “status epilepticus” after his current medication had been suddenly withdrawn. I gave him an intravenous injection of thiamine tetrahydrofurfuryl disulfide (TTFD), a synthetic derivative of thiamine) and this quickly stopped the continuous seizuring. I then started TTFD by oral administration but it was discontinued by a neurologist who saw the incident as “spontaneous remission and nothing to do with vitamin therapy”. Unfortunately, I did not have any data to be able to publish the case. Status epilepticus is the name given to a situation where the seizuring is continuous and often very difficult to stop. It usually occurs when a medication is suddenly withdrawn. Many years later, I discovered that thiamine deficiency could produce the same symptoms as brain hypoxia, thus giving rise to describing this deficiency as pseudo-hypoxia (false hypoxia). I had evidently treated the SE by relieving the pseudo-hypoxia in the brain cells responsible for this patient’s potentially fatal illness.

Maternal Diet and Neurological Development

There is growing concern about the long-term neurologic effects of prenatal exposure to maternal overweight and obesity, a result of malnutrition. The causes of epilepsy are poorly understood and in more than 60% of the patients no definite cause can be determined. Authors from the well-known Karolinska Institute showed that there was indeed a relationship between obesity in pregnancy and the risk of epilepsy in the offspring. Although the mechanism is not articulated, micronutrient deficiency may be culpable. Increasingly, it has become clear that a person’s weight does not correspond to their nutritional status. Indeed, in many cases, obesity is associated with a state malnutrition; a malnutrition we call high calorie malnutrition.

Clinical thiamine deficiency is defined by both consistent clinical symptoms and either a low whole-blood thiamine concentration, significant improvement, or resolution of consistent clinical symptoms after receiving thiamine supplementation. Of 400 obese patients, 66 (16.5%) were shown to have clinical thiamine deficiency. Their symptoms included gastrointestinal, cardiac, peripheral neurologic and neuropsychiatric manifestations, the characteristic symptoms of beriberi. Hypoxia threatens brain function during the entire life span, starting from early fetal age up to senescence. A relatively common condition in newborns is lack of adequate oxygen supply to the brain and is known as hypoxic-ischemic encephalopathy. This has been shown to correlate with multiple organ dysfunction and must surely be a severe legacy in the affected child.

The outstanding question then is whether poor diet, perhaps coupled with genetic risk in some cases, could be a substantial causative factor in widespread brain illness. Dr. Marrs and I have published considerable evidence that high calorie malnutrition, by inducing thiamine deficiency, is widespread throughout America and is responsible for a variety of brain related symptoms. With an excess of simple carbohydrate calories, the action of thiamine in burning those calories is overwhelmed. Thiamine might well be in a sufficient concentration for a healthy diet but insufficient for an excess of empty calories. It is the proper calorie/thiamine ratio that results in oxidative efficiency. Unfortunately, the many symptoms produced by thiamine deficiency in the brain are not recognized by the vast majority of physicians for what they represent. If thiamine deficiency is even suspected, they find a “normal” blood level of thiamine that is the usual result in moderate deficiency. The symptoms are falsely attributed to “a more acceptable diagnosis”. No appropriate laboratory tests are usually performed and in many cases the patient is diagnosed with psychosomatic disease, without even considering a necessary underlying mechanism.

High Calorie Malnutrition and Emotional Lability

This kind of malnutrition can severely affect emotional reactions, resulting in a variety of manifestations that include persistent anxiety, depression and bizarre behavior. We have even suggested that poor emotional control can lead to expressions of violence that hitherto have had no explanation for their almost daily occurrence in America. Poverty, poor education, environmental pollution and hedonism are all components that are predictable causative agents. When energy production in the brain is compromised by inefficient use of oxygen (oxidation), the affected person is unable to muster an adequate biological response in the process of adapting to virtually any form of stress. The affected patient is also wide open to succumbing from infection by any microorganism. Brain function becomes abnormal from lack of energy drive.

This may explain the breakdown in health in the children exposed to the stress of active (physical) or passive (mental) violence referred to at the beginning of this post. The well-known saying that “we are what we eat” should be broadened to “we behave according to what we eat”. So many books have advocated the principles of healthy nutrition, without producing much overall health improvement. There is a fairly consistent refusal to “give up” sugar, mainly because its ubiquitous consumption makes it hard to understand its inherent danger to complete health and its addictive properties. Perhaps a more logical attitude might be required to the use of nutritional supplements. The pharmaceutical industry has most people attuned to consumption of pills, so that a transfer of principle would probably be easy. However, it also demands a realization that disease can be reduced to an understanding of energy deficiency as the root cause.

Are Thiamine Deficiency Symptoms Too Narrowly Focused?

thiamine deficiency symptoms too narrowly focused

Much of our understanding regarding thiamine deficiency comes from early reports of illness from far-off lands, case reports that suggest rarity, and from rodent studies. While all of these are useful, none easily translate to the realities of this disease process on the ground, in the clinician’s office, or in the hospital. Do we really know what thiamine deficiency, or more appropriately, thiamine insufficiency looks like in everyday practice? Would we recognize it in the patients who walk through the doors of any medical facility? Probably not. And that is a problem.

We tend to think about nutrient deficiencies as emerging only in populations affected by starvation or absence-based malnutrition. This interpretation evolved from the early descriptions of beriberi, where the individuals most afflicted included Japanese sailors, Pacific Island communities, and regions afflicted by food scarcity. Later, alcoholics were added to the list of potential populations affected by thiamine deficiency. More recently, post gastric bypass patients, hyper-emetic pregnant women, and patients with critical illnesses were identified as at risk for deficiency. With each set of populations though, we are given the impression that thiamine deficiency is rare but easily recognized. It is neither, but the lens through which we view this disease process was focused generations ago on only the most severe examples, and that lens has remained ever since.

The Legacy of Early Scientists

The typical descriptions of thiamine deficiency disease, come from the perspective of the early investigators who described these conditions and have changed very little in decades since. Definitions of beriberi, which in Japanese means I cannot, I cannot, was, and still is, largely focused on the progression to heart failure in later stage deficiency. Here, there are two primary types of beriberi: wet beriberi, which is defined as high output cardiac failure with edema, and dry beriberi described as the central and peripheral nervous system and cardiovascular disturbances without edema. In recent years, gastrointestinal beriberi and neuritic beriberi have been added but they remain poorly recognized.

Likewise, our understanding of Wernicke’s encephalopathy (WE), a disease process that was first described by Carl Wernicke in 1881 and later associated with alcoholism and thiamine deficiency, is still described using Wernicke’s original triad of symptoms: mental confusion, ocular abnormalities, and ataxia. This despite the fact that 1) these symptoms represent a later stage manifestation of the disease process, where the deficiency is sufficient to produce brain damage and 2) these symptoms infrequently present, either alone or in combination, in most cases of WE. In fact, one study found that 80% of cases WE were identified only postmortem, meaning they were missed entirely while the patient was alive. Of those, only 16% had documentation of all three symptoms, 44% had one or two of the classic triad symptoms and 19% had none at all. This suggests that the classic triad, while a brilliant original observation, requires adjustment.

Korsakoff’s syndrome, a later stage and more severe form of thiamine deficient brain damage that includes neuropsychiatric and neurocognitive manifestations like confabulation, psychosis, and significant memory deficits, shares a similar lack of diagnostic clarity and is often mistaken for more traditionally defined psychiatric cases and dementias. Like Wernicke’s syndrome, Korsakoff’s is named after the scientist who first reported it in the late 19th century, a Russian by the name of Sergei Korsakoff. Like Wernicke’s, the lens through which we view this disorder owes largely to the original descriptions. Both syndromes are now combined as Wernicke-Korsakoff syndrome (WKS). For that reason, there are no clear data on the prevalence of Korsakoff’s syndrome or on how many patients progress through the different stages of brain damage associated with thiamine deficiency.

Those Rare Cases of Thiamine Deficiency

Modern case reports reinforce these legacy definitions of thiamine disease and continue to portray thiamine deficiency as a rare manifestation of severe illness. The literature is replete with cases of patients who demonstrate none of the classic symptoms associated with thiamine deficiency and yet are clearly deficient. Likewise, in each of these reports, the development of thiamine deficiency is considered rare. Indeed, the rareness of this condition is almost always explicitly emphasized in the text with statements like:

  • “A severe depletion is not commonly seen, except in cases of inadequate nutrition and/or alcoholism.”
  • “Cardiac beriberi, or heart failure due to thiamine deficiency, is considered rare in the developed world.”
  • Thiamine deficiency is rare in developed countries and is most commonly associated with chronic alcoholism. The other predisposing conditions include chronic dietary deprivation and impaired absorption or intake of dietary nutrients.
  • Nowadays, in the developed world it is relatively rare.

Next time you are reading a case study, or really, any report on thiamine deficiency, note the remarks of rarity. What if thiamine deficiency is not rare, but simply under-recognized? If we rarely consider it based on the lack of matching symptoms, how do we know what the real prevalence is?

Of Rodents and Men

The rodent research, although more adept at addressing the progression of deficiency symptoms across time, is still problematic. Aside from the obvious differences between rodents and humans, the highly controlled and contrived experimental conditions under which this research occurs in no way reflects the messiness of life. Rarely are we exposed to an absolute deprivation of a single nutrient, unless under some sort of duress or a medical error. More frequently, the progression to thiamine deficiency is an extended process of months to decades, where exposure to thiamine or anti-thiamine factors varies across time, and as a result, so too does the expression of illness.

From the rodent research, we do know, however, that there is a clear progression of symptoms across the period of deprivation. Here, among the first manifestations of thiamine deficiency are hair loss, apathy, and anorexia. These symptoms emerge within two weeks of thiamine deprivation. At about 4 weeks, neurological symptoms emerge, and death by cardiac arrest occurs at about 6 weeks.

Whatever the problems there are translating patterns gathered from animal research to those of human studies, and there are many, at least with these studies we can see the early indicators of problems. If a patient were to complain of new-onset hair loss, apathy, or anorexia, or even newly emerging neurological symptoms, more often than not, the symptoms would be dismissed as stress-related and relegated to the category of psychosomatically induced. An antidepressant or anxiolytic would be prescribed and that would be the end of it. Thiamine or other nutrient deficiencies would not be considered until a much later stage, if at all.

The Progression of Symptoms in Human Females

From some highly unethical studies conducted on female psychiatric patients in the late 1930s and early 1940s, we know that the human progression of thiamine deficiency does indeed mirror what is illustrated by animal research somewhat. The early symptoms are so benign that most would miss them. Similarly, as the symptoms build over time, although they worsen considerably, they remain more general than specific and might easily be ascribed to other conditions if one were not trained to consider thiamine.

A few notes about the studies. There were three in total, two with four women each and one with 11 women maintained on a diet of .15mg of thiamine per day for 147 days, .45mg of thiamine for 88 days, and 11 women at ~.15 – .2mg thiamine per day plus 1mg of thiamine given intermittently for up to 196 days, respectively. In the third study, where additional thiamine was provided, when averaged, the total thiamine consumed was ~.175mg per 1000 calories of food or .35mg for a 2000 calorie per day diet. Also, in this study, 5 of the 11 women were maintained on the diet for an undisclosed period before resuming a normal diet, while the remaining 6 were kept on the diet for as long as 196 days. This is approximately 30% of the recommended daily allowance needed to stave off deficiency symptoms and syndromes.

Before each study period, the women were provided a normal ‘healthy’ diet for up to 52 days. It is not clear what that constituted. Upon beginning the study, the diets became quite unhealthy, consisting of food products using white flour, sugar, tapioca, corn starch, polished rice, raisins, egg white, cottage cheese, American cream cheese, butter, hydrogenated fat, tea, and cocoa. Additional B vitamins, as well as some fat-soluble vitamins, were provided via supplement, even though thiamine was all but eliminated.

Below is a compilation of the observed symptoms in two of the case descriptions provided.

  • First few weeks: emotional instability, irritability, moodiness, anxiety, agitation, depression, reduced activity, and numerous, often vague, somatic complaints. Weakness and anorexia begin to present.
  • 30 days: anorexia, weight loss, epigastric distress, increasing weakness, periodic vomiting
  • 50 days: nausea and vomiting after meals, progressive weakness from low energy to bedridden, sometimes constipation
  • 70 days: constant nausea, severe weakness, apathy, confusion, numbness, and tingling in extremities
  • 90 days: inability to read or focus, aberrant to absent sensory recognition, tender calves, inability to stand from squatting position, hypoactive Achilles tendon reflex, nausea continues progressing to regular vomiting after meals
  • 110 days: appetite fails, apathy, vagueness and confusion, low blood pressure and heart rate at rest, rapid increase upon ordinary exertion, aberrant and absent sensory perceptions, aberrant and reduced reflexes, reduced flexion of ankles and knees, ataxia, inability to stand on toes.
  • 120 days: impaired pain perception on legs, loss of patellar and Achilles reflex, weakness in abduction, adduction, and flexion of thighs, weakness in the legs with limited ability to extend legs with quadriceps, inability to stand or walk without support, ankle and knee clonus absent, Babinski response absent.

One of these two subjects developed severe neurological defects at 120 days and so the experiment was stopped. The researchers noted that appetite had completely failed and remarked that ‘inanition seemed imminent. They also remarked that with 60-80mg of thiamine given orally and parenterally many, but not all, of the deficits. Appetite returned and strength was regained within the first week, and within 30 days, the less severely ill of the two women was mostly recovered. At 60 days, she was fully recovered. For the other women, recovery was incomplete, even after 120 days of treatment.  Of note, it was the younger and more active woman who suffered the most serious neurological deficits and who was unable to fully recover.

In the 88-day study, the most common and debilitating symptoms included vomiting and subsequent anorexia. The authors note:

We nevertheless are impressed by the degree of debility induced by the isolated withdrawal of thiamine. Fatigue, lassitude, and loss of interest in food developed early and increased progressively as the period of deficiency extended, to the point of intolerance for food. So great was this intolerance that uncontrollable vomiting, even after tube feeding and parenteral injection of solutions of sodium chloride and dextrose, automatically brought the observations to a close.

Also observed in this study, was an association between pre-deficiency energy levels and severity of illness propagated by the deficiency.

The time of development of symptoms and the time of development of severe symptoms differed among the subjects and seemed to be related to physical activity. The subjects who were more active showed symptoms earlier and were more seriously affected later than others who from the beginning were less energetic.

A few additional observations:

  • When thiamine was added intermittently, even though the total levels were still considerably below normal, symptoms improved for a period of a few days to a week. This happened repeatedly. The improvement was so noticeable that some of the women begged to remain on the higher levels of thiamine.
  • Pyruvate and lactic acid levels were higher throughout the period of thiamine deprivation but peaked differentially by individual, by duration of thiamine deficit, and across time, relative to when dextrose was given.
  • Pyruvate and lactic acid levels increased variably after meals and when dextrose was given but returned to the pre-meal/pre-dextrose basal rate within 120 minutes.

Finally, the most notable symptoms in each of the studies involved gastric distress, with vomiting, severe constipation, severe food intolerance, and anorexia. This, of course, was in addition to a decline in energy, polyneuropathy, changes in blood pressure, heart rate, and rhythm, and a decline in cognitive capacity.

So What Does Thiamine Deficiency Look Like?

Everything. And nothing. It is non-specific. It is the sickness behaviors of which Selye writes that underlie all illnesses. Thiamine deficiency looks like every other non-specific illness until it becomes severe enough to approximate some of the more well-recognized aspects of beriberi or WKS. Even in its most severe stages, however, the symptoms could easily be ascribed to other types of illness. Making matters more difficult, unlike the research presented above where thiamine is restricted consistently across time, in modern, developed countries, thiamine is rarely restricted so consistently. Thiamine consumption waxes and wanes across time, as does the demand. It is that mismatch between consumption or availability and needs that initiates the molecular events, deep in the mitochondria where thiamine is critical, that is responsible for the bevy of symptoms attributable to thiamine deficiency. This means that if we rely on the conventional diagnostic parameters, defined generations ago, we are all but guaranteed to miss it. Instead, we ought to be considering thiamine and other nutrient deficiencies in all cases of illness, whatever their manifestation, but that demands an entirely new lens through which to view health and disease; a lens that is quite at odds with the current model of medicine.
