Vitamin D3, also known as cholecalciferol, is a type of vitamin D that has been shown to be the true active form of vitamin D in the body. There are at least 10 known forms of vitamin D, but the most important are vitamin D2 (ergocalciferol) and vitamin D (cholecalciferol). Vitamin D3 is a fat-soluble vitamin known as the “sunshine vitamin” because moderate exposure of the skin to sunlight enables most people to synthesize their own vitamin D using ultraviolet light and cholesterol in the skin. it is synthesized primarily by the body itself, which contains a form of cholesterol in its skin that is transformed by sunlight into vitamin D3. Cholecalciferol, the most important form of the vitamin D family, primarily regulates calcium and phosphorus metabolism in the body.Vitamin D3 is converted from 7-dehydrocholesterol in the skin by UV exposure.

Function and Application:
1. Vitamin D3 can keep the metabolism of calcium and phosphorus normal, promote the body's absorption of calcium and phosphorus, and make plasma calcium and plasma phosphorus levels reach the saturation level. Cholecalciferol powder is often used in various health products.
2. Vitamin D3 promotes growth and calcification of bones and sound teeth; Vitamin d3 powder can be used to make vitamin d3 capsules
3. Vitamin D3 increases the absorption of phosphorus through the intestinal wall and the reabsorption of phosphorus through the renal tubules. Vitamin D3 maintains normal levels of citrate in the blood and prevents amino acid loss through the kidneys.
4. Vitamin D3 is mainly used in food, health food and other related products. As a nutritional supplement, vitamin D3 is used in liquid milk, margarine, dairy products and baby food. Vitamin d3 raw material is a common nutritional supplement.
