What is vitamin D?

This fat-soluble vitamin is naturally found in very few food-based sources. However, vitamin D’s functions in the body are very wide-ranging. When skin is exposed to UV sunlight, the body produces a form of vitamin D nearly identical to vitamin D3, also called cholecalciferol. Vitamin D3 may be more than three times as effective in raising D levels in the bloodstream and maintaining that concentration for a longer period of time than other forms of vitamin D supplements.
