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). Calcitriol acts as a ligand for the vitamin D receptor (VDR), a nuclear receptor that regulates intestinal calcium and phosphate absorption, renal calcium reabsorption, and bone mineralization. This mechanism is essential for maintaining serum calcium and phosphate levels and supporting skeletal health.
