Vitamin D3, also known as cholecalciferol, is a type of vitamin D that has been shown to be the true active form of vitamin D in the body. There are at least 10 known types of vitamin D, but the most important are vitamin D2 (ergocalciferol) and vitamin DChemicalbook3 (cholecalciferol). Cholecalciferol, also known as vitamin D3, is the most important form of vitamin D, which mainly regulates calcium and phosphorus metabolism in the body. Vitamin D3 is converted from 7-dehydrocholesterol in the skin by ultraviolet radiation.

Vitamin D3 can maintain the normal metabolism of calcium and phosphorus, and can promote the body's absorption of calcium and phosphorus. When it is deficient, children are prone to rickets. my country stipulates that it can be used in fortified margarine, and the dosage is 125-156 μg/kg; the dosage in fortified dairy products is 63-125 μg/kg; the dosage in fortified infant food is 50-100 μg/kg; in fortified milk and The amount used in milk beverages is 10-40 μg/kg; the maximum amount used in fortified solid beverages and ice cream is 10-20 μg/kg.

Vitamin D3 can maintain the normal metabolism of calcium and phosphorus, and promote the body's absorption of calcium and phosphorus. The utilization rate of vitamin D2 and D3 in pigs is the same, but the utilization rate of vitamin D2 in poultry is only 1/40-1/30 of D3. When vitamin D3 is deficient, the eggshell becomes thinner, the egg production rate decreases, and rickets occurs. The dosage is 1000-1500IU/kg.

Vitamin D is a fat-soluble vitamin. There are more than a dozen compounds known to have vitamin D effects, none of which are steroid derivatives, among which vitamin D2 and vitamin D3 are of great practical significance. The world is dominated by D3, and the "international standard substance" of vitamin D is also the pure crystalline Chemicalbook of D3. The main function of vitamin D is the metabolism of calcium and phosphorus, and it is difficult to promote calcium and phosphorus absorption and bone calcification. When the human body lacks D, the ability to absorb calcium and phosphorus decreases, and the level of calcium and phosphorus in the blood decreases, so that calcium and phosphorus cannot be deposited in bone tissue, and even bone salts will dissolve, which hinders the calcification of bones. Deficiency in children results in rickets, and in adults, osteomalacia. Japan mainly produces and uses D2. Among the various demands, medicines account for 30%, feed additives account for 65%, and food additives account for 5%. D2 and D3 as nutritional supplements can be used in liquid milk, margarine, dairy products and infant food according to the "Hygienic Standard for the Use of Food Nutrition Fortifiers (1993)" promulgated by the Ministry of Health of my country.

VitaminD3 acts through a receptor, a member of a family of ligand-dependent transcription factors that regulates the proliferation and differentiation of normal and cancer cells, and is antiproliferative and antimetastatic in breast, colon and prostate cancers Effect. Activated vitamin D receptors in the gut and bone also maintain calcium absorption and homeostasis.

Vitamin drugs, mainly to promote the absorption and deposition of calcium and phosphorus in the intestine, for the treatment of rickets and osteomalacia
