Ginkgo biloba Extract
Improves cerebral blood flow and peripheral circulation — modest evidence for memory in older adults and cognitive decline.
What the evidence says
Ginkgo Biloba helped in about half (7/11) of the studies that measured an effect — promising, but not unanimous.
Most evidence is from high-quality meta-analyses and randomised trials published 2008–2026 with a typical study size of 1,278 participants.

Confidence
HighWhat the studies found
By outcome
Ginkgo Biloba has an evidence score of 9/10 — very strong evidence based on 64 indexed studies, including 24 meta-analyses. Improves cerebral blood flow and peripheral circulation — modest evidence for memory in older adults and cognitive decline.
The commonly studied dose of Ginkgo Biloba is 120-240mg standardized extract. Research points to an estimated optimal dose around 240mg, with a minimum effective dose near 120mg. Individual response varies — start low and adjust.
The best time to take Ginkgo Biloba is in the morning. Taking it with food is preferred. Ginkgo biloba flavone glycosides and terpene lactones (ginkgolides and bilobalide) support cerebral blood flow and neuroprotection.
Omega-3

Ginkgo biloba extract comes from the leaves of the ancient ginkgo tree. It's commonly used for cognitive enhancement and circulation. Research shows modest benefits for memory in older adults and those with cognitive decline, but effects in healthy young adults are less consistent. Also used for peripheral circulation issues.

120-240mg standardized extract
Take with food
| Form | Type |
|---|---|
| 💊Standardized extract capsules (EGb 761) | Recommended |
| 💊Tablets | Alternative |
| 💧Liquid extract | Alternative |
EGb 761 is the most studied standardized extract. Avoid raw ginkgo leaves which contain toxic compounds.
Minimum: 6 weeks
Optimal: 12 weeks
Cycling: Not required
Note: Use standardized extract containing 24% flavone glycosides and 6% terpene lactones. Effects build over weeks.
Based on multiple meta-analyses including 2100+ participants showing benefits in mild dementia and memory. Effects modest and primarily in older adults or those with existing cognitive decline. Standardized extract (EGb 761) preferred.
Better recall, especially in older adults
Improved blood flow to extremities
Some experience headaches initially
Avoid due to bleeding risk and insufficient data
Avoid or use only under medical supervision
Increases bleeding risk
May reduce seizure threshold
Possible increased bleeding risk
Tip: Start with lower dose
Tip: Take with food
Tip: Reduce dose
Traditional combination for cognitive support
May enhance cognitive benefits more than either alone
Different mechanisms for memory support
Comprehensive cognitive enhancement
Both enhance cerebral circulation
Enhanced brain blood flow and cognition
Ginkgo Biloba is generally safe at recommended doses, with a few precautions worth noting. The most commonly reported side effects are headache, GI upset, dizziness. Use caution if any of these apply to you: Bleeding disorders; Before surgery (stop 2 weeks prior); Seizure disorders.
