Low Vitamin D Equals Low Cognition

Questions? Ask me!

Thinking or cognitive impairments in elderly men are shown in new research to be associated with low Vitamin D levels. A study of three thousand European men, 40-79 yrs old, demonstrated that people with reduced amounts of Vitamin D in their body did not score as well on a cognitive ability standardized test (assessment of individual’s attention and speed of information processing) as others did with standard levels of Vitamin D.

Their average level of Vitamin D among the elderly men was 63 nanomoles per liter. However, 90-140 nanomoles per liter is usually deemed as optimal. Men over age 60 with Vitamin D levels below 35 nanomoles per liter strongly illustrated less cognitive presentation. Research is still being conducted to see if Vitamin D supplementation can definitely improve cognition.
