Colecalciferol
Vitamin D3, the form of vitamin D that the skin makes from 7-dehydrocholesterol under UVB rays: activated by the liver and kidneys, it regulates the absorption of calcium and phosphorus and keeps bones healthy. This family brings together the active ingredient, pharmacopoeial impurities, metabolites, labelled standards and other impurities.
Did you know?The vitamin D3 in supplements usually comes from lanolin, the grease of sheep's wool: its 7-dehydrocholesterol is irradiated with ultraviolet light, just as happens in our skin.
