Ginkgo biloba
SaveA standardized leaf extract used for memory, circulation, and age-related cognitive support.
Quick verdict
A credible cognitive-support herb, especially in older adults, though benefits are usually modest rather than dramatic.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.

Dosage notes
The common clinical range is 120-240 mg/day of standardized extract divided once or twice daily.
Side effects
- Headache
- GI upset
- Possible increased bleeding risk
Who should be cautious

What this page cannot tell you
