Vitamin D3-5

Cholecalciferol, or Vitamin D3, is one of the members of the vitamin D family. It is needed by your body for the proper utilization of calcium and phosphorous, and for the assimilation of vitamin A. Vitamin D is commonly added to milk and other dairy products, but despite this, studies show that 40% of Americans are still deficient. Of those 22% are severely deficient. Since vitamin D is needed to maintain bone density it is vital to get these numbers down, especially among the elderly.
