Six-dimension breakdown
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 in How we scored this, above. 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.
Frequently asked questions
Auto-generated from Vyvata's scoring data for this product. For general questions about the store (shipping, returns, wholesale), see the site FAQ.
What is NMN and how does it relate to NAD+?
NMN (nicotinamide mononucleotide) is a direct precursor the body converts into NAD+, a coenzyme involved in cellular energy production and DNA repair that naturally declines with age.
Is 300mg of NMN a clinically studied dose?
Yes — 300mg per day falls within the range used in several human trials measuring NMN's effect on blood NAD+ levels.
Is the evidence for NMN's anti-aging benefits strong?
It's promising but still early: studies confirm NMN raises NAD+ levels, but large-scale, long-term outcome data on healthspan or lifespan benefits in humans doesn't yet exist.
Are there any regulatory concerns with NMN supplements?
Yes — the FDA has taken the position that NMN doesn't qualify as a legal dietary ingredient due to prior drug-investigation status, a matter that remains in dispute within the industry.
