Vitamin D3 Oil 1MIU~5MIU
Vitamin D (referred to as VD) is a fat-soluble vitamin, a cyclopentane polyhydrophenanthrene compound, which is related to sterols in groups, and functionally prevents vitamins from rickets, the most important being vitamins D3 and D2. The 7-dehydrogen radical under the human skin is irradiated with ultraviolet rays. . The main function of vitamin D is to promote the absorption of calcium and phosphorus by small intestinal mucosal cells. Calcium-binding protein is required for calcium absorption in the intestine. 1,25-dihydroxyvitamin D3 can induce the synthesis of this protein, promote Ca2+ absorption, promote calcium renewal and new bone formation, and promote phosphorus absorption and renal tubules. The cells reabsorb calcium and phosphorus, so they can increase blood calcium and blood phosphorus concentration, which is conducive to new bone formation and calcification. [1]
In general, adults often have exposure to sunlight without causing illness. Infants, pregnant women, nursing mothers and elderly people who do not often go outdoors can increase the vitamin D supplement to 10 μg per day (equivalent to 400 IU). Children who are deficient in vitamin D can develop rickets, and adults suffer from osteomalacia. [1]
