People with low levels of vitamin D in their blood were more than twice as likely to be diagnosed with depression than those with higher levels, according to a study in the British Journal of Psychiatry that included more than 31,000 participants. The hippocampus and other areas of the brain involved in regulating your mood contain vitamin D receptors, so low levels may affect the ability of these regions to function normally, researchers suggest.

A 2014 study published in the Journal of Sexual Medicine found that men with severe erectile dysfunction (ED) had significantly lower vitamin D levels than men with mild ED.
