Mechanism of action

Cholecalciferol is a fat-soluble vitamin that undergoes hydroxylation in the liver and kidneys to form the active hormone calcitriol (1,25-dihydroxyvitamin D3). The active metabolite binds to vitamin D receptors in the intestine, bone, and kidney to increase calcium absorption, maintain serum calcium and phosphate levels, and support bone mineralization. Additionally, vitamin D receptors are present on immune cells, where calcitriol modulates T-cell and B-cell function and inflammatory responses.
