Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Blueberry (Vaccinium spp.) is used to support circulation to the brain, and this use has some scientific validation. Blueberries are rich in anthocyanins, flavonoid compounds that have demonstrated antioxidant and vasoprotective effects. Several clinical studies and animal experiments suggest that blueberry consumption may improve vascular function, including cerebral blood flow. For example, a 2017 randomized controlled trial published in the European Journal of Nutrition found that older adults who consumed wild blueberry juice daily for 12 weeks showed improved brain perfusion and cognitive performance compared to placebo. Other studies have shown that anthocyanins can enhance endothelial function, reduce oxidative stress, and decrease inflammation, all of which contribute to better circulation.

Blueberry’s benefits for brain circulation are thought to arise from both direct effects on blood vessels—by increasing nitric oxide production and vasodilation—and indirect effects by protecting vascular cells from oxidative damage. While not traditionally used specifically for brain circulation, the growing body of human and animal research provides moderate support for this application. However, most studies are small and short in duration, and more rigorous trials are needed to confirm these effects and determine optimal dosing. Overall, blueberries can be considered a promising dietary strategy for supporting cerebral circulation, especially in aging populations.
