Product Description

Product introduction of Pure Vitamin Powder

Cholecalciferol, also called vitamin D3, which is a form of vitamin D. Cholecalciferol is formed when the 7-dehydrocholesterol that is produced after cholesterol dehydrogenation is exposed to ultraviolet light, suggesting that the source of vitamin D for cholecalciferol is 7-dehydrocholesterol. Cholocalciferol is hydroxylated in the liver to form 25-hydroxycholecalciferol, which is then hydroxylated in the kidneys to 1,25-dihydroxycholecalciferol, which has been shown to be 50% more active than cholecalciferol and is 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 booster. Meanwhile, vitamin D, a fat-soluble vitamin, is also regarded as a hormone precursor acting on calcium and phosphorus metabolism. It has also been called the "sunshine vitamin" because of its close relationship with sunlight.

Functions of Pure Vitamin Powder

The main function of this vitamin is to help the body to promote the absorption of calcium and phosphorus, in a very simple way it helps to replenish calcium, if the body is deficient in this vitamin it will not be able to allow the body to fully absorb the calcium, which will naturally lead to the symptoms of calcium deficiency because there is no way to get enough calcium.

Causes of vitamin D deficiency in humans.

1. Excessive growth

Both breast milk and cow's milk contain less vitamin D to meet the normal developmental needs of the child and are not absorbed smoothly due to the inappropriate ratio of calcium to phosphorus in cow's milk. As a result, milk-fed children are more likely to develop rickets than breast-fed children. Meanwhile, children's staple food is mainly rice paste and thin rice. These foods contain high levels of phytic acid and fibre, which can interfere with the absorption of calcium and phosphorus.

2. Influence of other diseases

For example, chronic gastrointestinal diseases, liver and kidney diseases, etc.

3. Insufficient sunlight exposure

Too little time outdoors to receive adequate sunlight makes vitamin D3 deficiency easy, which is why children are prone to rickets.
