What is Vitamin D3?
 
Vitamin D3, also known as cholecalciferol, is a kind of vitamin D. The 7-dehydrocholesterol generated after cholesterol dehydrogenation can be irradiated with ultraviolet rays to form cholecalciferol. Therefore, the original vitamin D of cholecalciferol is 7- Dehydrocholesterol.

Vitamin D is a fat-soluble vitamin and is also regarded as a hormone precursor that acts on calcium and phosphorus metabolism. It is closely related to sunlight, so it is also called "sunshine vitamin".Vitamin D is a general term for a family of complexes with the same structure of A, B, C, and D rings, but different side chains. 

Vitamin D3 (cholecalciferol) is mainly synthesized by the human body itself. The skin of the human body contains a kind of cholesterol, which becomes vitamin D3 after being exposed to sunlight.Therefore, if the child can fully accept direct sunlight for more than 4-6 hours, the vitamin D3 synthesized by himself can basically be satisfied.However, due to the rise of skin cancer caused by ultraviolet radiation, air pollution, and weather changes in various places, the time for people in various countries to receive sunlight is decreasing, and many countries have clearly stipulated that they should limit the time for receiving sunlight. Therefore, worldwideVitamin D is generally deficient.In addition, vitamin D3 can also come from animal foods, such as liver, especially cod liver oil extracted from fish liver of seafood.Except for a few animal foods, vitamin D3 is mainly formed from 7-dehydrocholesterol in the skin after ultraviolet radiation, and 7-dehydrocholesterol is produced by the transformation of cholesterol, so some people call it the sun vitamin..
