The studies I've seen relaying the same sentiment of no appreciable benefit only looked at a single outcome, normally bone density or bone fracture occurrence. Vitamin D levels affect expression of almost 300 different genes in humans (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3604145/) so looking at a single outcome to gauge the entire efficacy of that vitamin is absurd and disappointing that so many other doctors push their narrow minded interpretations of those same limited studies.

My thesis argued that we should not be testing supplementation levels, instead we should be testing the effects of maintaining people at various serum levels of vitamin D year-round.
