If this vital nutrient but under appreciated protects brain cells themselves same or a key signaling pathways in the brain is unclear, but the effect is clearly measurable.
The study, a joint effort between the University Manchester, experts and colleagues from other European centers, appears in the Journal of Neurology, Neurosurgery and Psychiatry.
This latest work follows the research who made news in January suggesting high levels of vitamin D may help prevent mental decline of brain aging.
Dr. Iain Lang, a member of the UK and U.S. team conducted the previous work, agrees that this latest study adds to evidence that vitamin D could be very good for the brain.
The study included men in 8 European countries as part of the European Male Aging Study (EMAS), and entailed assessing the mental agility of subjects with three different standardized tests of cognition.
Blood samples were taken to measure levels of vitamin D. The evaluations also participated as physically active than men were, how they work in everyday life and reports on mood or depression.
In the end, men with higher levels of vitamin D was better on cognitive tests and their performance was consistently better than those with the highest low.
One surprise was that the most striking difference appeared in subjects over 60 years of age.
Why might this be?
Researchers are not sure, but suggest that the vitamin could trigger an increase in hormones in the brain protection, although at present animal studies is again the theory of
Other evidence suggests that vitamin D may work to calm a more active immune system or perhaps increase the levels of antioxidants that work to detoxify the brain.
So while experts can not explain precisely how vitamin D, which remain confident that it does have an impact on cognitive function related to age.

In 2008, the American Academy of Pediatrics made recommendations for vitamin D intake, which were double the previous dose, which most of us grew up on.
And as the sunlight is also a natural source of this important vitamin, as we age, our skin is less able to absorb vitamin D from the sun, for older people more dependent on sources food supplements (or) to this key nutrient. What's more, we know that sunscreens with SPF 15 or higher, popular in our fight against skin cancer to block almost all vitamin D synthesis in the skin. Being obese or overweight also makes your body can make vitamin D while in the sun.
Estimates of vitamin D deficiency indicate that 50% of adults and children in America are not getting enough.
And seeing that vitamin D is increasingly linked to health benefits beyond the brain, reducing things like arthritis, osteoporotic fractures, not to mention diseases heart and even some cancers, there has never been a better time to make sure you are getting enough.
