The dose resulted in an average of 14.2% conversion of provitamin D₃ to previtamin D₃ and photoproducts within in vitro models. When administered once every week for 92 days, the dose failed to significantly modify the decline of serum 25(OH)D; however, the decline of vitamin D₃ seemed to level off. The overall effect of the UVB dosing was weak, and more frequent doses are probably needed to restore and maintain vitamin D status.
