Why this scored 48/100
Generic NMN 500mg from Marathon Ginseng. NMN evidence base is real (Martens 2018, Yoshino 2021) at 250-1000mg dose range. Held below Standard by (1) 'Marathon Ginseng' as an NMN vendor suggests non-specialist positioning — ginseng-focused brand branching into NMN typically without the NMN-specific quality controls; (2) no third-party COA for NMN purity or content verification; (3) no GMP certification disclosed; (4) NMN products in this quality tier commonly have documented label-accuracy issues (see our /blogs/news/nmn-gmp-certified-what-to-check-buyers-guide post for the full quality-check framework). Would move to Standard 55+ with GMP + third-party COA + named manufacturer.

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.
