Scientific studies1 over the past 17 years have indicated that vitamin D3 may protect the skin from ultraviolet (UV) sunlight damage. This occurs when adequate levels of activated vitamin D3 in the skin’s cells increase the skin’s ability to withstand UV exposure. However, when UV light strikes the skin of people who are low in vitamin D3, high levels of nitric oxide, a free radical, are released in the body, causing potential DNA damage.
Thus, a natural vitamin D3 tan can only occur when your vitamin D3 levels are optimal. How do know if your vitamin levels are adequate? Get your blood tested by your healthcare practitioner (or via reputable on-line pharmacies). The name of the test is 25-hydroxy (OH) vitamin D. A number of experts believe that a healthy level of circulating vitamin D3 is between 50-80 ng/mL. Personally, my vitamin D3 level hovers around 100 ng/mL.
So, by increasing your vitamin D3 levels through supplementation, not only will you significantly improve your overall health and well-being, you also may get a great tan!
