Editorial: Vitamin D Binding Protein, Total and Free Vitamin D Levels in Different Physiological and Pathophysiological Conditions.

Keywords: vitamin D binding protein; total 25-hydroxyvitamin D; free 25-hydroxyvitamin D; 1,25-dihydroxyvitamin D; bioavailable 25-hydroxyvitamin D Vitamin D binding protein (DBP) is a major plasma carrier for vitamin D and its metabolites. DBP has a single binding site for all vitamin D metabolites with a high affinity for 25(OH)D, thereby creating a large pool of circulating 25(OH)D, which prevents rapid vitamin D deficiency.
