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 target tissues, promoting intestinal calcium and phosphate absorption, regulating bone mineralization, and modulating immune cell differentiation and function. At a dose of 1200 IU daily, it is used for vitamin D supplementation and maintenance of adequate serum vitamin D levels.
