It also regulates inflammation and immunological function, among many other functions in the body. Vitamin D is also known as "calciferol." It is a fat-soluble vitamin that occurs naturally in a few foods, is added to others, and may be obtained as a dietary supplement. Endogenous production occurs when ultraviolet (UV) photons from sunlight impact the skin and activate vitamin D synthesis. Sufficient vitamin D prevents rickets in youngsters and osteomalacia in adults. Vitamin D, together with calcium, helps prevent elderly persons from osteoporosis.
