Cheap Supplements: Vitamin D
- Vitamin D
Vitamin D is a group of fat-soluble prohormones, the two major forms of which are vitamin D2 and vitamin D3. Vitamin D's major biologic function is to maintain normal blood levels of calcium and phosphorus. Vitamin D aids in the absorption of calcium, helping to form and maintain strong bones. It promotes bone mineralization in concert with a number of other vitamins, minerals, and hormones. Without vitamin D, bones can become thin, brittle, soft, or misshapen. Vitamin D prevents rickets in children and osteomalacia in adults -- skeletal diseases that result in defects that weaken bones.
