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. 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.
