Vitamin D3

Vitamin D3 is a fat-soluble vitamin that is naturally present in very few foods.  It is also produced endogenously, (through the skin), when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthisis.  It is essential for promoting calcium absorption in the gut. Without sufficient Vitamin D3, bones can become thin, brittle or misshapen.
