Application

Ergocalciferol has been used as a component of the diet for rats, to study its bioavailability from ultraviolet-irradiated D2-rich yeast. It has also been used as a standard for identification and quantification of vitamins, as part of a study to determine the nutritional composition of food fishes.

Biochem/physiol Actions

Ergocalciferol (vitamin D2) and 25-Hydroxycholecalciferol (vitamin D3) are the two forms of vitamin D, which are activated in vivo by hydroxylation. Vitamin D2 and D3 may be used in a wide range of studies to assess their effects on function such as immune function and calcium homeostasis.

Ergocalciferol is used for antirachitic treatment. Vitamin D has an active role in bone mineralization. Severe deficiency of this vitamin has been associated with osteomalacia and rickets.

General description

Vitamin D2 or ergocalciferol is available through dietary supplements or plant sources. It is a provitamin, which is fat-soluble.
