Label snapshot
What the product contains and what one serving costs, according to our catalog. Label amounts are not personal dose recommendations.
| Ingredient | Amount per serving |
|---|---|
| NR | 300 mg |
| Resveratrol | 10 mg |
| Quercetin | 5 mg |
| Fisetin | 400 µg |
Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.
These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.
This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.
This product scores well on transparency and value, but its core weakness is that it markets itself as a multi-pathway stack while functionally being a single-ingredient product. The 300mg of NIAGEN NR is properly dosed and backed by grade B evidence, but resveratrol (10mg), quercetin (5mg), and fisetin (0.4mg) are present at trace amounts far below their trial doses.
The science behind each active ingredient, independent of which brand sells it.
The NAD+ precursor with the strongest safety file and EU approval.
The famous red-wine molecule; longevity claims have outrun the human evidence.
Best-studied 'senolytic' ingredient, though evidence is early.
Highly-hyped senolytic; the strong evidence is in mice, not people.
Every active in this formula, its declared dose per serving, the dose used in the primary human trial, how much of that trial dose this product delivers, and the evidence grade for the ingredient itself.
| Ingredient | Dose / serving | Research dose | % of research | Evidence grade |
|---|---|---|---|---|
| NR | 300 mg | 300 mg | 100% | B |
| Resveratrol | 10 mg | 500 mg | 2% | C |
| Quercetin | 5 mg | 500 mg | 1% | B |
| Fisetin | 0.4 mg | 500 mg | 0% | C |
Percentages are dose per serving ÷ primary trial dose. Below 50% means the formula is unlikely to reproduce the trial outcome for that active. Grade A = multiple large human RCTs. Grade F = no human evidence. How grades work. Full glossary →

300mg of clinically-dosed NIAGEN NR is the real backbone here, matches the standard trial dose, but the resveratrol/quercetin/fisetin add-ons are trace amounts (10mg/5mg/0.4mg) inside 'bioavailability-enhanced' blends without listed amounts, so don't expect meaningful standalone effects from those three.
If you are the manufacturer or brand owner of NAD+ Cell Regenerator and Resveratrol Elite and believe any data on this page is incorrect (wrong dose, wrong ingredient, wrong price, missing certification, outdated status), you can request a correction.
We review every request, verify it against primary sources, and publish any accepted change with a dated note. Corrections from brand owners are treated the same as corrections from anyone else: verified before they move.
