Vitamin D Binding Protein (VDBP) significantly varies in acute stress due to rapid fluid shifts. This variation leads to a significant change in the free 25OH Vitamin D concentration, at constant total 25OH Vitamin D levels. Therefore several research groups have studied the importance of free 25OH Vitamin D during acute stress.
