Vitamin D is produced in skin exposed to ultraviolet B radiation. Vitamin D has also been implicated in a growing list of functions related to human biology. The role traditionally attributed to the vitamin D system is to regulate the amount of calcium and phosphorus in the blood by ensuring correct intake from intestines and secretion. Vitamin D plays an important role in the maintenance of an intact and strong skeleton. Vitamin D is classified as a vitamin because it is required for metabolism and deficiency can result in disease, including rickets and osteoporosis. It is manufactured in the skin by the activation of a sterol (7-dehydrocholesterol) by ultraviolet radiation (sunlight). Vitamin D is required for the formation of strong bones and teeth. The two major forms of vitamin D are D 2 (or ergocalciferol) and D 3 or cholecalciferol.
