Nature's Way Ginkgold / Ginkgold Max are EGb 761; other products are generic \"24%/6%\" (identical on paper, not the trial extract) or unstandardized whole-leaf. Ginkgolic acids are allergenic/cytotoxic contaminants that pharmacopeias cap at <5 ppm (Boateng 2022, PMID 36065842; cytotoxic but not mutagenic in Berg 2015, PMID 25448085), yet almost no product discloses its level. \"verdict\": egb761 (the trial extract), generic-standardized-ga-disclosed (24%/6% AND discloses a ginkgolic-acid limit), generic-standardized (24%/6%, no disclosure), whole-leaf (unstandardized). costPerServing = live Amazon price / servings. IMPORTANT EVIDENCE CONTEXT: the most independent evidence is null - the Cochrane review calls benefit \"inconsistent and unreliable\" (Birks 2009, PMID 19160216) and two large RCTs show ginkgo does NOT prevent dementia (GEM, DeKosky 2008, PMID 19017911; GuidAge, Vellas 2012, PMID 22959217). The positive signal is narrow: EGb 761 at 240 mg/day for TREATING mild-moderate dementia, in manufacturer-linked meta-analyses. Dose 120-240 mg/day. Caution with anticoagulants/antiplatelets and before surgery.", "headline": { "productsCompared": 11, "egb761TrialExtract": 2, "discloseGinkgolicAcid": 4, "cheapestQualityBrand": "Doctor's Best", "cheapestQualityCostPerServing": 0.11, "cheapestEgb761Brand": "Nature's Way", "cheapestEgb761CostPerServing": 0.43, "note": "Only 2 products are the EGb 761 trial extract, and only 4 disclose a ginkgolic-acid limit.
