How it works
Cholecalciferol (vitamin D3) is formed in the skin under influence of UV rays and metabolized in two hydroxylation steps at first in the liver and then in the kidney tissue into the biological active metabolite 1,25-dihydroxy-cholecalciferol. 1,25-dihydroxy-cholecalciferol is involved fundamentally in the regulation of the calcium and phosphate balance together with parathyroid hormone and calcitonin.
