Vitamin D is a group of fat-soluble prohormones,
the two major forms of which are vitamin D2 (or ergocalciferol) and vitamin
D3 (or cholecalciferol). The term vitamin D also refers to metabolites
and other analogues of these substances. Vitamin D3 is produced in skin
exposed to sunlight, specifically ultraviolet B radiation.
Vitamin D plays an important role in the maintenance of
several organ systems.
Vitamin D regulates the calcium and phosphorus levels
in the blood by promoting their absorption from food in the intestines,
and by promoting re-absorption of calcium in the kidneys.
It promotes bone formation and mineralization and is
essential in the development of an intact and strong skeleton.
It inhibits parathyroid hormone secretion from the
parathyroid gland.
Vitamin D affects the immune system by promoting
immunosuppression, phagocytosis, and anti-tumor activity.
Vitamin D deficiency can result from; inadequate intake
coupled with inadequate sunlight exposure, disorders that limit its
absorption, conditions that impair conversion of vitamin D into active
metabolites, such as liver or kidney disorders, or, rarely, by a number of
hereditary disorders. Deficiency results in impaired bone mineralization,
and leads to bone softening diseases, rickets in children and osteomalacia
in adults, and possibly contributes to osteoporosis.
