| Popis: | VITAMIN D, the “sunshine vitamin”, is produced in the skin when ultraviolet radiation is absorbed by the pro-vitamin 7-dehydrocholesterol1. The endogenous vitamin, together with dietary vitamin D, is then apparently converted in the liver to 25-OH vitamin D, and this active metabolite facilitates the intestinal absorption of calcium and the uptake and release of calcium by the skeleton2,3. |
