Rating (out of 5): 2

Bilberry (Vaccinium myrtillus) has a long history of traditional use in European herbal medicine, primarily for visual and vascular health. While it is not as well-established as a brain booster as some other herbs, it has occasionally been used in traditional medicine systems to support memory and cognitive function. This traditional use is largely based on the general belief that antioxidants—such as the anthocyanins found in bilberry—can help preserve overall health, including brain health, by reducing oxidative stress and improving circulation.

However, scientific evidence for bilberry’s direct effect on memory and brain function is limited. Some preliminary laboratory and animal studies suggest that the antioxidants in bilberry may have neuroprotective effects, potentially reducing inflammation and oxidative damage in the brain. A few small human studies have explored the impact of bilberry or related berries (like blueberries) on cognition, with mixed results and often using higher doses or concentrated extracts not typical of dietary supplementation.

Overall, while bilberry is sometimes used traditionally to support brain health, there is insufficient high-quality scientific evidence to strongly validate its effectiveness for improving memory or brain function. Its primary reputation remains in supporting eye health and vascular function rather than cognitive enhancement.
