    25-hydroxyvitamin D3 (calcifediol) is a prohormone produced in the liver via hydroxylation of vitamin D3 (cholecalciferol). It is a precursor for the synthesis of calcitriol or 1,25-dihydroxyvitamin D3. In a clinical setting, it is a biomarker to determine the status of vitamin D in the body. 25-Hydroxyvitamin D3 (6,19,19-d3) is a deuterated vitamin D3 wherein C-6 and C-19 protons are replaced by deuterium.
