Vitamin D and Brain Function
Can vitamin D support healthy brain function? Research suggests it may play a role.
A study published in the Journal of Neurology, Neurosurgery, and Psychiatry (May 21, 2009) found that men with higher vitamin D levels performed significantly better on cognitive tests than those with lower levels. The study followed 3,369 men participating in the Male Aging Study and assessed attention, psychomotor speed, and information-processing ability.
Men with higher vitamin D levels showed:
-
Better performance on tests of psychomotor speed
-
Faster visual scanning and information processing
-
The strongest benefits among older participants
These findings indicate that adequate vitamin D may help support cognitive performance, particularly as people age.
