Deficiency
Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and many other biological effects. In humans, the most important compounds in this group are vitamin D3 (also known as cholecalciferol) and vitamin D2 (ergocalciferol).
The major natural source of the vitamin is synthesis of cholecalciferol in the low…
Use of supplements
Several forms (vitamers) of vitamin D exist. The two major forms are vitamin D2 or ergocalciferol, and vitamin D3 or cholecalciferol. Vitamin D without a subscript refers to either D2 or D3, or both, and is known collectively as calciferol.
Vitamin D2 was chemically characterized in 1931. In 1935, the chemical structure of vitamin D3 was defined and shown to result from the ultraviolet irradiationof 7-dehydrocholesterol. A chemi…
Dietary intake
The active vitamin D metabolite calcitriol mediates its biological effects by binding to the vitamin D receptor (VDR), which is principally located in the nuclei of target cells. The binding of calcitriol to the VDR allows the VDR to act as a transcription factor that modulates the gene expression of transport proteins (such as TRPV6 and calbindin), which are involved in calcium absorption in the i…
Recommended serum levels
An estimated one billion people worldwide are either vitamin D insufficient or deficient. Vitamin D deficiency is widespread in the European population. A diet with insufficient vitamin D in conjunction with inadequate sun exposure causes vitamin D deficiency. Severe vitamin D deficiency in children causes rickets, a softening and weakening of bones, which is a rare disease in the developed world.
