Vitamin D

Cholecalciferol; Vitamin D3; Ergocalciferol; Vitamin D2

Vitamin D is a fat-soluble vitamin. Fat-soluble vitamins are stored in the body's fatty tissue.

Vitamin D benefit

Vitamin D promotes retention and absorption of calcium and phosphorus, primarily in the bones. Too much vitamin D may have the opposite effect of taking calcium from the bones and depositing it in the heart or lungs, reducing their function.

Vitamin D deficit

Because vitamin D is essential for the body's utilization of calcium, a deficiency may result in severe loss of calcium and consequently a softening and weakening of bones.

Vitamin D source

Like most vitamins, vitamin D may be obtained in the recommended amount with a well-balanced diet, including some enriched or fortified foods. In addition, the body manufactures vitamin D when exposed to sunshine, and it is recommended people get 10 to 15 minutes of sunshine 3 times a week.
