Suddenly everyone is talking about using Vitamin D to prevent or lessen the impact of Covid-19. "There is a certain amount of correlation, but huge uncertainty about causation. Studies have shown that vitamin D deficiency impairs the immune system, and someFormer CDC Director Dr. Tom Friedan pointed to some of those studies in "There are many crackpot claims about miracle cures floating around, but the science supports the possibility -- although not the proof -- that Vitamin D may strengthen the immune system, particularly of people whose Vitamin D levels are low," Friedan wrote.

"The fuss began when researchers in the US and UK began comparing the vitamin D levels of various countries to their coronavirus death rates and found an association: The countries who reported lower levels of vitamin D also had higher death rates from Covid-19.Was that association caused by a lack of vitamin D or by other factors at play during the pandemic?After all, people around the world who are at highest risk of vitamin D deficiency -- those with underlying chronic disease, an older age or darker skin color -- are also the same people at highest risk of dying from Covid-19.Having a darker skin makes it more difficult for the skin to absorb enough sun to manufacture vitamin D. Our bodies are also less efficient at creating vitamin D as we age, thus many of the elderly are typically vitamin D deficient.
