Skin color makes a big difference in the amount of vitamin D you get from the sun, which is important to be aware of because, for most people, the majority of vitamin D intake still comes from sun exposure. In this newsletter we discuss statistics that show that many diseases are much more prevalent in those with darker skin. Could vitamin D levels contribute to these discrepancies? Can raising everyone's vitamin D levels eliminate racial disparity and thus reduce negative health outcomes?
