- Whether every ingredient has its own milligram line, or several are grouped in a 'blend' with one total.
- How many capsules or scoops make a serving, and how many servings the container holds.

How we scored this product Show the full breakdown
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.
Quick verdict
Our summary
Why this scored this way
This Thorne HealthTech ResveraCel scores 7.0, making it a mid-tier product with both strengths and weaknesses. It delivers 300mg of NR, inside the studied range of 100–1000mg with grade B evidence (promising human data, not yet comprehensive). Transparency is a clear strength (score: 9.0), with third-party testing and a public lab certificate. At $1.75/day it's among the more expensive options in Longevity stack.
What drives the score up
- Dose-evidence score of 6.3 shows decent alignment with trial doses.
- Quality transparency of 9.0: tested by independent lab with a public lab certificate.
- NR is dosed at the full research level with grade B evidence (promising human data, not yet comprehensive).
What drags it down
- Resveratrol (150mg is 30% of the 500mg trial dose) is significantly under-dosed.
- Quercetin (200mg is 40% of the 500mg trial dose) is significantly under-dosed.
- Betaine (TMG) (150mg is 5% of the 3000mg trial dose) is significantly under-dosed.
- At $1.75/day it's on the expensive side.
Why you'd choose it
- You want NR from a Thorne HealthTech product.
- You prioritise tested by independent lab products with public lab certificates.
Why you might skip it
- You need a full trial dose of resveratrol (this product under-doses it).
- You want a cheaper option (this is $1.75/day).
Question 1
Does the molecule work?
Does the molecule work?
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.
A methyl donor added to NAD+ formulas as a supporting cofactor, not a headline active.
Full ingredient breakdown
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 | 150 mg | 500 mg | 30% | C |
| Quercetin | 200 mg | 500 mg | 40% | B |
| Betaine (TMG) | 150 mg | 3000 mg | 5% | 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 →

These are consumer sentiment signals. They do not measure whether the product actually works. See our evidence section for that.
What others say, with a source hierarchy
We treat external opinion very differently depending on where it comes from. Tier A is our strongest signal. Tier C is background sentiment only. Tier Rejected is what we excluded, listed openly so you can see what we discarded.
These reviews are aggregated from third-party sources, not written by NO1GEVITY. Each entry shows its source, retrieval date, and whether the source has an affiliate or paid relationship. We do not edit reviews to change their meaning. Disclosure policy.
Independent deep reviews, lab tests, certificates of analysis
Our strongest external evidence. Long-form independent reviews, physical-product lab work, and third-party certifications.
Registered dietitians and physicians, without affiliate ties
Credentialed commentary from clinicians who disclose no paid relationship. Useful as supporting critique but not a substitute for a clinical outcome trial.
Nurse practitioner explains the NAD+ / quercetin / resveratrol rationale for ResveraCel. Notes mechanistic plausibility but no product-level outcome trial.
Aggregated sentiment (Trustpilot, Reddit)
Mood indicator only. We never use aggregate stars as evidence of efficacy.
Aggregate score 2.4 / 5. Complaints concentrate on delivery, billing, and customer service — not on product quality or purity.

Claim check, vendor claims vs. our reading of the evidence
Not medical advice. We list the strongest claims made by the brand and check each against traceable evidence.
Regulatory status
Rules change often. We record when we last verified each row. See the full regulatory timeline →
What we could not verify
We list this openly. If a claim isn't backed by a source we can trace, we'd rather flag it than repeat it.
- The exact elemental-NR content of the 415 mg NRHM dose in this formulation.
- Whether ResveraCel carries the NSF Certified for Sport mark on its current label — unlike NiaCel 400, this was not confirmed on Thorne's own product page.
- The full protocol and any unpublished results from the terminated NCT05297032 quercetin trial.
- Whether the 250 mg Quercetin Phytosome dose is bioequivalent to unencapsulated quercetin doses used in the cited resveratrol/quercetin combination research.
Editorial notes
NR + resveratrol + methyl-donor in one bottle. Doses below single-ingredient research levels.
