Product Usage
Vitamin D3, also known as cholecalciferol, is a form of vitamin D that is proven 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 (ergocalcitol) and vitamin DChemicalbook3 (cholecalciferol). Cholecalciferol, also known as vitamin D3, is one of the most important forms 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 irradiation.
Vitamin D is a fat soluble vitamin. There are more than a dozen compounds known to have the effect of vitamin D, and there are no lineoid sterol derivatives, among which vitamin D2 and vitamin D3 are of important practical significance. The world is dominated by D3, and the "international standard material" of vitamin D is also a pure crystal of D3. The main function of vitamin D is the metabolism of calcium and phosphorus, which is difficult to promote calcium and phosphorus absorption and bone calcification. When the human body lacks D, the ability to absorb calcium and phosphorus is reduced, and the levels of calcium and phosphorus in the blood are reduced, so that calcium and phosphorus Chemicalbook can not be deposited in bone tissue, and even bone salts will dissolve, which hinders the calcification of bones. Deficiency causes rickets in children and osteomalacia in adults. In Japan, D2 is mainly produced and used, and in various demands, medicine accounts for 30%, feed additives account for 65%, and food additives account for 5%. According to the Hygienic Standard for the Use of Food Nutrition Fortifiers (1993) issued by the Ministry of Health, D2 and D3 as nutritional supplements can be used in liquid milk, margarine, dairy products and infant food.
