No single vitamin has been proven to stop dementia or extend lifespan. The National Institute on Aging says no vitamin or supplement is currently recommended specifically to prevent Alzheimer’s disease or cognitive decline.

Here’s what you should know about the vitamins most often discussed:

Vitamin B12: Essential for nerve function. A deficiency can cause memory problems and should be treated.
-
Vitamin D: Important for bone and muscle health, but supplementation has not been shown to prevent dementia.

B vitamins: Correcting deficiencies matters, but taking extra B vitamins has not reliably prevented cognitive decline.

Vitamin E: Research has not established that it prevents dementia in healthy people.NCCIH+1
