[ Introduction ]
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 D3, also known as cholecalciferol, is a kind of vitamin D. The 7-dehydrocholesterol generated after dehydrogenation of cholesterol can form cholecalciferol after being irradiated by ultraviolet light, so that means the original vitamin D of cholecalciferol is 7 -Dehydrocholesterol.
[ Main Functions ]
1. Vitamin D3 can promote the absorption of calcium and phosphorus in the human intestine, effectively saturate the body's calcium and phosphorus elements, promote the balance of citric acid in the human serum, and effectively reduce electrolyte imbalance.
