Product Description
Product introduction of Pure Vitamin Powder
Cholecalciferol, also known as vitamin D3, is a form of vitamin D. The 7-dehydrocholesterol produced after the dehydrogenation of cholesterol is exposed to ultraviolet light to form cholecalciferol, which means that the vitamin D source of cholecalciferol is 7-dehydrocholesterol. Cholecalciferol is hydroxylated in the liver to form 25-hydroxycholecalciferol, which is then hydroxylated in the kidneys to 1,25-dihydroxycholecalciferol, which is 50% more active than cholecalciferol and has been shown to be the true active form of vitamin D in the body. 1,25-dihydroxycholecalciferol is a hormone secreted by the kidneys, so in effect cholecalciferol is also a hormone proponent. At the same time, vitamin D is a fat-soluble vitamin and is also seen as a hormonal precursor acting on calcium and phosphorus metabolism. It is also known as the "sunshine vitamin" because of its close relationship with sunlight.

Functions of Pure Vitamin Powder
1. To improve the absorption of calcium and phosphorus by the body and to saturate plasma calcium and plasma phosphorus levels.
2. Promoting growth and skeletal calcification and promoting sound teeth
3. Increasing phosphorus absorption through the intestinal wall and increasing phosphorus reabsorption through the renal tubules
4. Maintaining normal levels of citrate in the blood
5. Preventing the loss of amino acids through the kidneys.
Causes of vitamin D deficiency in humans.
1. Insufficient sunlight exposure
Too little time outdoors to receive adequate sunlight makes vitamin D3 deficiency easy, which is why children are prone to rickets.
2. Insufficient intake of vitamin D3
Whether it is breast milk or cow's milk, the vitamin D contained in it is relatively small and cannot meet the needs of the child's normal development. At the same time, due to the improper ratio of calcium and phosphorus in cow's milk, it cannot be absorbed smoothly. As a result, milk-fed children are more likely to develop rickets than breast-fed children. At the same time, children's staple food is mainly rice paste, thin rice, etc. These foods contain a lot of phytic acid and fibre, which can affect the absorption of calcium and phosphorus.
3. Excessive growth
Whether it is breast milk or cow's milk, the vitamin D contained in it is relatively small and cannot meet the needs of the child's normal development, and because the ratio of calcium and phosphorus in cow's milk is not appropriate, it cannot be absorbed smoothly. As a result, milk-fed children are more likely to develop rickets than breast-fed children. At the same time, children's staple food is mainly rice paste, thin rice, etc. These foods contain a lot of phytic acid and fibre, which can affect the absorption of calcium and phosphorus.
4. Influence of other diseases
For example, chronic gastrointestinal diseases, liver and kidney diseases, etc.
