25 OH Vitamin D

Product name : 25 OH Vitamin D

Descriptions :
25-hydroxyvitamin D, also known as 25-hydroxycholecalciferol, calcidiol or abbreviated 25-OH Vit D, is the main vitamin D metabolite circulating in plasma. It circulates either as 25-OH Vit D2 or 25-OH Vit D3, depending on its precursor. 25-OH Vit D is the storage form of vitamin D in the human body. Beside that important function, 25-OH Vit D shows little intrinsic biological activity, at least in physiological concentrations. Some activity of 25-OH Vit D has been reported on intestinal calcium adsorption.
