The Anti-Alzheimer's Vitamin

Vitamin D May Prevent Alzheimer's


Vitamin D, already linked to increased mobility in older people, may also protect women against getting  Alzheimer’s or going into mental decline,  according to two new studies

One study, conducted at the Angers University Hospital in France, found that older women with a higher dietary intake of vitamin D had a lower risk of developing Alzheimer’s.

The second study, done at the VA Center in Minneapolis, found that lower levels of vitamin D in women are linked to a higher risk of cognitive impairment or decline. Both are published in 

The Minneapolis study, led by Yelena Slinin, MD, analyzed vitamin D levels among 6,257 women who were tested both for levels of the vitamin and for cognition. Women who had very low levels of vitamin D were had higher odds of cognitive impairment. Those who were already cognitively impaired and had low levels of the vitamin had higher odds of cognitive decline.

The French study, led by Cedric Annweiler, MD, Ph.D., found that among the 498 women they studied, those who had higher levels of vitamin D had a lower risk of developing Alzheimer’s than other dementias.

Earlier this year, researchers discovered that those who don’t get enough vitamin D may be at increased risk of developing mobility limitations.

Vitamin D comes from exposure to sunlight as well as dietary supplements and foods like salmon, fortified milk and fortified cereal.


Both studies appear in the Journal of Gerontology Series: A Biomedical Science and Medical Sciences.
