Six-dimension breakdown
Why this scored 62/100
300 mg nicotinamide riboside (Niagen) per capsule. NR has RCTs showing NAD+ elevation in blood (Martens 2018, Conze 2019) but hard clinical endpoints for longevity or healthspan remain unproven — the mechanistic story is well ahead of the outcome data. 300 mg is within the RCT-tested range. Life Extension is a legitimate brand with GMP. Standard — mechanism plausible, outcomes unproven.
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.

Strongest: Transparency at 70/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Formulation at 68/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Evidence at 55/100 (quality of published RCT support for the active ingredients at the label dose) and Sustainability at 50/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
Is Life Extension NAD+ Cell Regenerator third-party tested?
