Dr. Lonsdale thoughts on COVID-19

COVID-19 and Thiamine: An Interview with Dr. Derrick Lonsdale

Print Friendly, PDF & Email

In the summer 2013, a geneticist we were seeing for my daughter ordered a test. Little did I know that test would contribute to a change in the course of my daughter’s life as well as a new area of study and advocacy for my career. This is my first time to write for Hormones Matter, so let me start by introducing myself. I am Kristi Wees and I am a pediatric patient advocate with EmpoweredAdvocacy.com as well as a national consultant for patient advocacy, empowerment, and engagement in the field of pediatric genetics. I was trained as a chemist at Penn State University with graduate training at UCLA. It was the journey that my daughter’s health took our family on that made me realize exactly why I had studied chemistry.

Fast forward to 2020, nearly 7 years later and now a pandemic with COVID-19, and I again realize how that 2013 test has sent us on an incredible journey. That 2013 test was for transketolase, which is a blood test to determine a vitamin (thiamine, B1) insufficiency. At the time, my daughter was struggling with autistic-like behaviors, severe fatigue, suspected mitochondrial disease, gastrointestinal concerns, severe food intolerances, and chemical sensitivities. The future looked bleak and hopeless.

After this test result came back, I began to search the literature about thiamine and found the work of Dr. Derrick Lonsdale. With guidance and a prescription from our medical team, we began our daughter on thiamine supplementation. In 2016,  I had the distinct honor of meeting Dr. Lonsdale in person. In 2019, I had the honor of interviewing him with Patricia Lemer for an episode called, “I Have A Child Who…Has Tantrums”.

Our first meeting in 2016, from left to right: Kristi Wees (author of this post), Dr. Derrick Lonsdale, and Patricia Lemer (author of Outsmarting Autism).

A few weeks ago, I was reading the medical literature (here, here, and here) and watching anecdotal reports (here) regarding COVID-19 and began to see some clues that made me think of Dr. Lonsdale’s work on thiamine. I reached out to him via email and he shared with me that he too was seeing similar red flags and that he was frustrated because at 96 years old, and having dedicated his life to research on this vitamin, he believed it could be helping so many critically ill patients. He asked if I had any ideas about how to help him get the word out.

Here is the idea we came up with: a recorded interview. Dr. Lonsdale is a gentleman with whom I have come to know as a friend, mentor, and researcher and whose body of work helped my child thrive. I believe he possesses wisdom that has been forgotten and largely ignored by modern medicine. Listen to the interview, you won’t be disappointed.

Shortly after releasing the video last week I came across this study: Intravenous Thiamine Is Associated With Increased Oxygen Consumption in Critically Ill Patients With Preserved Cardiac Index. Which again confirms Dr. Lonsdale’s conviction that thiamine can greatly improve the current situation in many ICU’s nationwide.

After treatment with thiamine, and many dietary, environmental and lifestyle changes, plus a whole lot of answered prayers, my daughter is thriving today with no residual behavioral, medical, neurological, developmental or learning challenges. Could thiamine also help overcome COVID-19? Possibly.

Kristi Wees received her bachelors degree in chemistry from The Pennsylvania State University where she was one of the inaugural graduates of the Schreyer’s Honors College. She went on to complete her masters degree studies at UCLA in Chemistry. Utilizing her extensive industrial, academic and research experience, as well as, hands-on medical and clinical know-how, Kristi navigated her own daughter’s medical journey back to restored health. Through this process, Kristi became a passionate advocate for all children no matter what the diagnosis and all of her work is founded on the belief that every family deserves the best quality of life together with their child.


  1. I’m wondering if allicin is a breakdown product of TTFD? Or perhaps something very allicin-like.

    Allicin stimulates TRPA1 which is tied to cold sensitivity. Having used TTFD for a couple of years I’ve become very cold sensitive and suspect this might be the cause.

    ” TRPA1 is activated by various chemicals (Bandell et al., 2004) including allyl isothiocyanate (the pungent compound in mustard oil), allicin (from garlic), cinnamaldehyde (from cinnamon), menthol (from mint), tetrahydrocannabinol (from marijuana), nicotine (from tobacco), and bradykinin”

    I don’t think would necessarily apply to everyone but is specific to my genetics and a possible mutation in the TRPA1 protein.

  2. Hi
    I am 10 weeks into thiamine supplemenatation and I am losing my balance. First weeks of thiamine i improved my POTS symptoms of heavy legs, now I have gone the other way. Is this normal? My magnesium levels are up after transdermal application for the last 2 years.

    • Are you taking the other B vitamins (and/or a multivitamin) alongside?

      I’ve found a recurrence of what look like vitamin deficiency symptoms by supplementing only some vitamins without others. We know that dietary B1 needs ATP for it to be either transported into cells and/or be converted to its coenzyme form (I can’t remember which offhand). And taking B1 without the other nutrients needed for ATP production could increase need for those, and hence have a knock-on effect on your ability to use B1. I know Dr Lonsdale recommends taking B1 alongside a well-rounded multivitamin.

    • It HAS to be a vitamin imbalance. Thiamine is the LEADER of the orchestra but it is not the orchestra! Add the B complex and a multivitamin.
