Vitamin D and mental agility

Vitamin D could help to keep people mentally sharper as they get older. Vitamin D is produced by the body when skin is exposed to sunlight and is also found in certain foods, such as oily fish.

Researchers from the University of Manchester compared the cognitive performance of more than 3,000 men, aged between 40 and 79, and found that those who had low levels of vitamin D did worse on a task designed to test mental agility. The link between low levels of vitamin D and poor performance held true even after allowing for levels of education, depression, physical activity and measures of physical performance.
