Vitamin D is proving its worth beyond its bone-building and immune-boosting reputation. According to a recent study, the ‘sunshine vitamin’ may also help protect the brain from Alzheimer’s disease, especially for anyone over the age of 75.
"There is good evidence that vitamin D gets into all cells of the body, including the brain," said study author Joshua Miller, chair of the department of nutritional sciences at Rutgers University School of Environmental and Biological Sciences in New Brunswick, N.J. “So it's possible that vitamin D protects the brain from developing the plaques and tangles that are associated with Alzheimer's disease.”
Researchers found that those who were deficient in the vitamin were more prone to memory decline and had a more difficult time with problem solving and short-term memory compared to those who had adequate levels.
The National Institutes of Health recommends 600 IU for men and women between the ages of 1 and 70 and 800 IU for anyone over the age of 70. In addition to supplementing, some Vitamin D sources include fatty fish (like salmon, tuna and mackerel) and fish liver oils as well as dairy (milk, for example, contains about 100 IU per cup). How do you ensure your Vitamin D levels are up to par?
