The point: Why suffer vitamin D deficiency in particular if you have any form of disease when it is perfectly safe to have the serum level of a sunny country?
Now the serum level for vitamin D in a sunny country is 54 ng/ml to 90 ng/ml per Grant and Holick. To achieve this level takes a different amount of sun exposure and supplementation for everyone as each person’s rate of use of vitamin D is different. There is no need to wait for some study to come out and say with certainty that vitamin D will treat or prevent this disease or that disease when it is safe at an extremely beneficial level.
Scientist will take many years to make treatment studies show the benefits of vitamin D for a multiple of reasons. No one wants to fund the studies when there is no profit to be made and government funding for treatment studies can be extremely slow. However, through anecdotal experiences that are communicated this paradigm shift can move very quickly.
