Ergocalciferol, also under the name vitamin D2, is a type of vitamin D found in plants and yeast. It has no antirachitic activity. It helps the body to absorb calcium and phosphorus. It is used as a dietary supplement. It is used in the treatment of hypoparathyroidism (a condition in which not enough parathyroid hormone can be produced by the body), refractory rickets (softening and weakening of bones that does not respond to treatment, it is also known as vitamin D resistant rickets), and familial hypophosphatemia (rickets or osteomalacia caused by an inherited condition with a decreased ability to break down vitamin D in the body). Ergocalciferol is also used as a rodenticide.
It can be applied to biochemical studies; its clinical drug belongs to a lipid-soluble vitamin which can promote the intestinal absorption of calcium and phosphorus which plays a role of facilitating the calcification of bone. It is clinically used for prevention and treatment of rickets in children and adult osteomalacia.
Vitamin D2 can maintain the normal metabolism of calcium and phosphorus and can also promote the body's absorption of calcium and phosphorus. Upon its deficiency, the children are easy to get rickets. China ruled that it can be applied for strengthening margarine with the usage amount being 125~156 μg/kg; its usage amount in fortified dairy is 63~125μg/kg; the usage amount in strengthening infant and children food used is 50~100μg/kg; the usage amount in strengthening milk or milk beverage is 10~40μg/kg; the maximal allowable usage amount in the strengthening solid drinks and ice cream is 10~20μg/kg.
It is mainly applied to the prevention and treatment of rickets, osteomalacia, and infant tetany psychosis.
Vitamin D aids in the absorption of calcium and has central roles in bone formation and maintenance, hypertension, cancer and immunity. Vitamin D may be obtained from many dietary sources, including eggs and fish, and is synthesized in the skin by the conversion of 7-dehydrocholesterol to vitamin D3 by ultraviolet light. Vitamin D2 is produced in fungi, including yeast, and invertebrates from ergosterol in response to ultraviolet radiation. In vertebrates as well as host organisms, vitamin D2 is metabolized first to 25-hydroxyvitamin D2 and subsequently to the active 1,25-dihydroxyvitamin D2. Differences in the metabolism and action of vitamin D2 vs. vitamin D3 in mammals is a current topic of research interest.
The synthetic form of vitamin D. Prepared from ergosterol by UV irradiation in a suitable solvent. Commercial solutions are usually made with propylene glycol or sesame oil. Antirachitic
Vitamin d2 is fat-soluble, and is stable unless oxidized. It is necessary for growth and maintenance of teeth and bones and the normal utilization of calcium and phosphorus; it is used medicinally in the treatment of rickets and as a dietary supplement. Its sources include fish liver and vitamin d-fortified milk.
