Product Introduction:
Vitamin D3 (Cholecalciferol), also known as cholecalciferol, is a kind of vitamin D, which is formed by 7-dehydrocholesterol generated after dehydrogenation of cholesterol by ultraviolet irradiation.
The molecular formula of vitamin D3 is C27H44O, and it is a fat-soluble vitamin.
It is also regarded as a hormonal agent forerunner that acts upon calcium as well as phosphorus metabolic process.
It is mostly manufactured by the human body itself. The human skin consists of a sort of cholesterol, which will become vitamin D3 after direct exposure to sunlight.
Proven to be real active type of vitamin D in the body.
There go to least 10 known kinds of vitamin D, yet the most essential are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).
Cholecalciferol, the most important form of vitamin D, mainly regulates calcium and phosphorus metabolism in the body.
Vitamin D3 is known as the “sunshine vitamin” because most people can synthesize their own vitamin D from UV rays and cholesterol in the skin with moderate exposure to the sun.
It is mainly composed of 7-dehydrocholesterol in the skin, which becomes vitamin D3 when exposed to sunlight.
If the kid can totally get direct sunlight on the skin for more than 4 to 6 hours, the vitamin D3 manufactured by itself can primarily satisfy the demands.

Product Usage:
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.
