Why this scored 48/100
Ginkgo and ginseng are two real, well-studied botanicals — ginkgo (as EGb 761 standardized to 24% flavone glycosides and 6% terpene lactones) has GEM Study (DeKosky 2008) data on dementia prevention (null) and multiple smaller cognitive-function trials (mixed); Panax ginseng (as G115 standardized to 4% ginsenosides) has mental-fatigue and cognitive-performance evidence at 200-400mg/day. But this combination product discloses neither the milligram dose per active nor the standardization percentage — the two variables that determine whether either ingredient is present at studied levels. A 60mg + 60mg combo is a homeopathic gesture; a 240mg EGb 761 + 400mg G115 combo would be a clinically relevant dose. Without disclosure, defaults to zero on formulation under the Zero-Assumption Rule. Auto-failed under proprietary_blend_hides_dose.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.
How to read the Evidence dimension
80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
0–19: No credible evidence base or unverifiable claims.

Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
