Ginkgo biloba improves blood flow to the brain, supporting memory and concentration. Studies show positive effects particularly on cognitive function in older adults. In younger people, the effect is more modest but still noticeable for working memory and reaction speed. You need at least 6-8 weeks of consistent use to see results.

The standard dose is 120-240 mg of standardized extract (24% flavonoid glycosides, 6% terpene lactones) per day, divided into 2-3 doses. For memory and cognitive support, 120 mg daily is usually sufficient. A higher dose (240 mg) is appropriate when more intensive support is needed.

Yes, ginkgo biloba can enhance the effect of blood-thinning medications (warfarin, aspirin) and increase the risk of bleeding. It can also affect the effectiveness of epilepsy medications. If you take regular medications, consult your doctor before using ginkgo. Stop ginkgo at least 2 weeks before any planned surgery.

Initial effects such as improved focus and mental clarity may appear within 1-2 weeks. The full effect on memory and cognitive function typically develops after 6-12 weeks of consistent use. Ginkgo is not fast-acting like caffeine but supports brain health as a long-term course.
