Did a masters on Vit D.

Multiple overdoses of over 1 million IU have been recovered from without obvious long-term damage present in near term follow up.

Out of vitamin D’s many potentially clinically positive effects some of the clearest and best evidence is for increased muscle strength.

Personally I take between 5000-10000 IU D3 daily depending on exposure to sun intensity.

Care to share your thesis? Sounds interesting! What was your degreee in?

The hypothesis was: is it beneficial to supplement vitamin D to reach the maximum levels achieved through sun exposure year-round?

Conclusion: these types of studies did not exist at the time, but the risks of doing such studies would be minimal, and such studies would be able to test for the effects of higher dose supplementation that were lacking at the time. Potential benefits include increased muscular strength and bone strength.
