Is there a link between vitamin D3 deficiency and schizophrenia?

Bryan Roth, M.D., Ph.D.

There are several studies which have suggested some link between both high and low levels of vitamin D and schizophrenia, although definitive studies are unavailable...

Certainly, if there is a vitamin D deficiency it should be corrected, and your family physician or endocrinologist would be able to determine if intervention is needed.
