FIG. 2. Time course of the rise in serum 25OHD after a single oral dose of 50,000 IU of either cholecalciferol (vitaminD3) or ergocalciferol (vitamin D2) to two groups of 10 normal men each. Error bars are 1 SEM. The zero-change line incorporates a correction for the seasonal rise in 25OHD occurring at the time this study was performed.
