Ginkgo Biloba and Cognitive Decline

Ginkgo biloba, a popular brain health supplement, does not seem to prevent cognitive decline or dementia according to scientific research. Although over a third of older Americans use ginkgo supplements, randomized controlled trials involving thousands of participants have shown inconsistent and unreliable evidence of its benefits. Two large-scale trials, funded by different entities, conclusively demonstrated that ginkgo leaf extract does not prevent dementia, highlighting the importance of cautious consumption of such supplements.
