Brain-Friendly Vitamin Lowers Dementia Risk

With Alzheimer’s and dementia on the rise—and no cure in sight—there’s only one true solution:

Prevention.

Fortunately, researchers have identified one key nutrient for better brain function and reduced dementia risk.

The best part?

You can get it for FREE.

The sun is a gift that keeps on giving. In addition to its vital role in setting your circadian rhythm, it’s your body’s best source of vitamin D.

And according to a recent study, having plenty of vitamin D is tied to…

• better brain function and
• a lower risk of dementia.

Researchers measured the blood and brain levels of vitamin D in volunteers to determine its impact on brain function.

Vitamin D and cognitive function were checked while the participants were still alive. Then, researchers measured the active form of vitamin D in four brain regions after their death.

They discovered higher brain levels of 25(OH)D3 were associated with better cognitive function.

Those volunteers with higher brain concentrations of D3 also had up to 33 percent lower odds of having dementia or mild cognitive impairment.

Additionally, higher D3 levels in a part of the brain called anterior watershed white matter were connected to…

• better episodic memory (memory of specific events) and
• perceptual speed (the ability to note differences between items).

Of course, you can’t measure your brain levels of D until after death.

However, another key finding in this study was that blood levels of total and free 25(OH) D3 were correlated with D3 levels in all four brain regions.

This lets us know that your current blood levels likely indicate how much is in your brain as well.

Like I always say, don’t guess about your D. Get your blood levels tested. If they’re lower than 60 ng/ml, start taking steps to improve your levels.

The best way to do that is to spend more time in the sun, but you can also start eating more vitamin-D-rich foods, like salmon, sardines, beef liver, oysters, and eggs.
