Vitamin D3 Usage
1. Vitamin D is a fat-soluble vitamin. There are more than a dozen compounds known to have a vitamin D effect, and no steroidal derivatives, of which vitamin D2 and vitamin D3 are of great practical significance.
2. The world is dominated by D3, and the "international standard substance" of vitamin D is also the 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.
3. 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 lowered, so that calcium and phosphorus cannot be deposited in the bone tissue, and even the bone salt is dissolved, which hinders the calcification of the bone. If a child is deficient, he or she will get sick. In adults, she will get bone softening.
4. In Japan, the production and use of D2 is much. Among various requirements, medicine accounts for 30%, feed additives account for 65%, and food additives account for 5%. According to the "Sanitary Standards for the Use of Food Nutrition Enhancers (1993)" promulgated by the Ministry of Health of China, D2 and D3 as nutritional supplements can be used for liquid milk, margarine, dairy products, and infant foods.
