Description
Cholecalciferol is a naturally occurring form of vitamin D which is obtained from dietary sources, such as fish, or through the conversion of 7-dehydrocholesterol by ultraviolet light. It is subsequently metabolized to 25-hydroxyvitamin D3 and the active form 1,25-dihydroxyvitamin D3 by cytochrome P450 isoforms in the liver. It could prevent proliferation of cancer cells.
