Why this scored 25/100
Prevagen Regular Strength — 'Memory Improvement Supplement' in product name. Auto-fail: unverified_disease_claim. Same apoaequorin evidence problem as other Prevagen SKUs. FTC v. Quincy Bioscience ongoing; Madison Memory Study didn't support advertised benefits; oral protein degrades in stomach before reaching brain.
Auto-fail rule triggered: Unverified disease claim.
The product markets a disease-treatment, -prevention, or -cure claim (memory loss, cardiovascular disease, cancer, etc.) without published double-blind RCT evidence at the label dose to support that claim. Under FDA and FTC guidance this level of claim requires drug-approval standards of evidence. See the full rubric →

Evidence & sources
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.
