15 minutes of full-body UV exposure from the sun is estimated to provide the equivalent of 20-30,000 IU Vitamin D3.
There is a definite need for studies that better determine the effective dose for D3.
My research led me to the conclusion that studies should be done based not on standardized supplementation, but instead supplementation to a standardized blood serum level.
