| Cholecalciferol (Vitamin D3, Activated 7-dehydrocholesterol) | Vitamin D3 is cholecalciferol, one of the vitamin D family. Vitamin D3 has been used to prevent and treat breast cancer, prostate and possibly other cancers and Vitamin D3 is essential to maintain bone density. Vitamin D3 is necessary for the ultilization of Calcium and Phosphorus, and for the assimilation of Vitamin A. It also has a strong immune enhancing effect. In many ways vitamin D acts as a hormone and is potent in minute quantities. One microgram of cholecalciferol has 40 IU of vitamin D activity. Vitamin D is necessary for utilization of calcium and phosphorus. Activated 7-dehydrocholesterol, cholecalciferol, also called activated 7-dehydrocholesterol, cholecalciferol. The biologically active form of Vitamin D. It is transported by the blood and the liver converts it to 25-Hydroxycholecalciferol (25-Hydroxyvitamin D, Calcidiol) which is converted in the kidneys to 1, 25-Di hydroxycholecalciferol (1,25-Dihydroxyvitamin D, Calcitriol).
