Vitamin D is a group of fat-soluble secosteroids responsible for intestinal absorption of calcium and phosphate. In humans, the most important related compounds of vitamin D are vitamin D2 and vitamin D3. Cholecalciferol and ergocalciferol are unique as they constitute what is known as vitamin D and can be ingested from the diet and/or supplements. The body can also synthesize vitamin D when sun exposure is adequate. Although vitamin D is commonly called a vitamin, it is not actually an essential dietary vitamin in the strict sense, as it can be synthesized in adequate amounts by most mammals exposed to sunlight. An organic chemical compound is only scientifically called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from its diet. However, as with other compounds commonly called vitamins, vitamin D was discovered in an effort to find the dietary substance lacking in a disease, namely, rickets, the childhood form of osteomalacia. Additionally, like other compounds called vitamins, in the developed world, vitamin D is added to staple foods, such as milk, to avoid disease due to deficiency.
