About Ginkgo
One of the most studied herbal supplements with hundreds of clinical trials. Standardized extracts (EGb 761) have the strongest evidence base. Large trials (GEM, GuidAge) found no benefit for dementia prevention in healthy elderly. Moderate evidence for improving blood flow and peripheral circulation. May interact with anticoagulants. No established RDA/UL.
