Product Description
Vitamin D3 is also known as cholecalciferol. It is converted from 7-dehydrocholesterol in the skin by ultraviolet irradiation and is one of the most important forms of vitamin D. Vitamin D is a fat-soluble vitamin, which acts as a hormone precursor of calcium and phosphorus metabolism. It is closely related to sunlight, so it is also called "sunshine vitamin".
