Low vitamin D levels in older men may impair their thinking, according to a new study.

The study, published in the May 2009 Journal of Neurology, Neurosurgery, and Psychiatry, found that men with suboptimal levels of vitamin D scored worse on a cognitive test than men with normal levels. Participants ranged from 40 to 79 years of age.

The study’s authors emphasize that the difference between the scores was small, so they don’t yet know if dietary supplementation of vitamin D could offer cognitive benefits.
