How It Works
Cholecalciferol (vitamin D3) is synthesized in the skin under UV exposure and metabolized in
the liver and kidneys to form the active metabolite 1,25-dihydroxy-cholecalciferol. This active
form is key in regulating calcium and phosphate balance alongside parathyroid hormone and
calcitonin.
