Vitamin D3 with Cas 67-97-0
What is Vitamin D3?
Vitamin D3, also known as cholecalciferol. Vitamin D3 has physiological functions of promoting intestinal calcium absorption, regulating calcium and phosphorus metabolism, inducing bone calcium and phosphorus deposition, promoting bone growth, and preventing rickets.
Vitamin D3 is a fat soluble vitamin known as the “sunshine vitamin” because when the skin is moderately exposed to sunlight, most people can synthesize their own vitamin D using ultraviolet radiation and cholesterol in the skin. It is mainly synthesized by the human body itself, and the skin of the human body contains a type of cholesterol that, when exposed to sunlight, becomes vitamin D3. So, if children can fully receive direct sunlight on their skin for 4-6 hours or more, the synthesized vitamin D3 can basically meet their needs.
Physiological functions and effects
1) Improve the absorption of calcium and phosphorus by the body, and achieve saturation levels of plasma calcium and phosphorus;
2) Promote growth and bone calcification, and promote healthy teeth;
3) Increasing phosphorus absorption through the intestinal wall and increasing phosphorus reabsorption through the renal tubules;
4) Maintain normal levels of citrate in the blood;
5) Prevent amino acid loss through the kidneys.
