Metabolism

7-Dehydrocholesterol is the precursor of vitamin D3 and forms cholecalciferol only after being exposed to solar UV radiation and also indoor sun tanning machines.


Cholecalciferol is then hydroxylated in the liver to become calcifediol (25-hydroxyvitamin D3).


Next, calcifediol is again hydroxylated, this time in the kidney, and becomes calcitriol (1,25-dihydroxyvitamin D3). Calcitriol is the most active hormone form of vitamin D3.
