The most important source of vitamin D for all individuals is the sunlight-driven conversion in skin of 7-dehydrocholesterol to cholecalciferol. |
This is true not only for cholecalciferol and ergocalciferol obtained from the diet but also for cholecalciferol that is generated from 7-dehydrocholesterol in the skin during exposure to ultraviolet light. |
The Committee deleted in List B cholecalciferol cholesterol and pyridoxamine because of the lack of official purity criteria. |
All patients received 800 IU of cholecalciferol and 1,000 mg of calcium carbonate. |
Both groups received cholecalciferol and calcium carbonate oral supplementation. |
Vitamin D3, or cholecalciferol, is one of the two main variants of vitamin D, a fat-soluble vitamin. |
