Why this scored 63/100
Neurogan Health Resveratrol Capsules deliver 1,400 mg of micronized resveratrol per two-capsule serving in a vegan, cGMP-manufactured capsule. Neurogan is a real, US-based CBD-adjacent brand with a transparent website and cGMP-certified production. Micronization is a defensible bioavailability step — reduces particle size and improves dissolution — though it does not resolve resveratrol's fundamental low oral bioavailability (~1% systemic). Human RCT evidence for resveratrol is mixed: positive signals on endothelial function and glycemic markers in some diabetic populations (Movahed 2013, Bhatt 2012), but disappointing longevity/insulin-sensitivity results in healthy adults (Yoshino 2012, Poulsen 2013 — 'resveratrol supplementation in nonobese women does not improve metabolic function'). Standard tier — honest, single-ingredient, correctly dosed for the category, held back from Verified by the low absolute bioavailability and the mixed clinical picture.

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.
