Vitamin D3 is mainly used as a vitamin drug, which mainly promotes the absorption and deposition of calcium and phosphorus in the intestine, and is used for the treatment of rickets and osteomalacia.
The world is dominated by D3, and also the “worldwide standard material” of vitamin D is also a pure crystal of D3.
The primary function of vitamin D3 is the metabolic rate of calcium and also phosphorus, and also it is hard to advertise calcium as well as phosphorus absorption as well as bone calcification.
When the body does not have Vitamin D, the capability to absorb calcium and phosphorus declines, and the degree of calcium as well as phosphorus in the blood reduces, so that calcium and phosphorus can not be transferred in bone tissue, and even bone salts will dissolve, which hinders the calcification of bones.
When vitamin D3 is deficient, the eggshell becomes thinner, the egg production rate decreases, and rickets occurs.
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.
Activated vitamin D receptors in the gut and bone also maintain calcium absorption and homeostasis.
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.
