Is 50 ng of vitamin D too high, just right, or not enough

Overview of the controversy

Most experts say 40 ng is good
Some experts say 50 ng is much better for disease prevention
Some experts say 50 ng is too much (high latitude, black skin)
Concern that >40 ng may be too much if taking some chemotherapy and unable to reduce the dose taken
Some experts feel 50 ng is not enough to TREAT some diseases
