One of the world's most widely used herbal supplements, studied for cerebral blood flow.

Ginkgo Biloba leaf extract comes from one of the oldest living tree species. Modern research has focused largely on its effect on circulation, including blood flow to the brain.
Cognitive performance depends on a steady supply of oxygen and nutrients reaching brain tissue. Ginkgo's role in the formula is circulatory support — a different angle from the more direct memory- or nerve-focused ingredients.
Some research has measured short-term increases in cerebral blood flow following Ginkgo supplementation. The broader research picture on cognitive outcomes specifically is mixed — a genuinely honest summary, not a uniformly positive one — with circulatory support being the more consistently documented finding.
Ginkgo has mild blood-thinning properties. Consult your physician before use if you take anticoagulant or antiplatelet medication, have a bleeding disorder, or have upcoming surgery scheduled.
