Every ingredient amount is disclosed
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

How to read this report
What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.
What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.
What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.
Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.
Panel, decoded
The front number is the blend total, not the named ingredient
MARKETING1 g — per-serving claim
PANELQuercetin (from Sophora japonica Bud Extract) 150 mg + the other listed actives = 1 gBeta-Nicotinamide Mononucleotide 500 mg + Trimethylglycine 250 mg + Quercetin (from Sophora japonica Bud Extract) 150 mg + Resveratrol (from Polygonum cuspidatum Root Extract) 100 mg
blend totalWe did the comparison: the front label uses 1 g, but the named ingredient quercetin (from sophora japonica bud extract) is 150 mg on the panel. The remainder is the other listed actives.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Beta-Nicotinamide Mononucleotide | 500 mg | — | |
| Trimethylglycine | 250 mg | — | |
| Quercetin (from Sophora japonica Bud Extract) | 150 mg | — | |
| Resveratrol (from Polygonum cuspidatum Root Extract) | 100 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a listed “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; any remaining comparison concerns the front-label framing.

Every check we ran
Confirmed evidence
What checked out3
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Exact trademark owner identified
USPTO lists Reus Research, LLC (LIMITED LIABILITY COMPANY) in Delaware, USA for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
The review count moved gradually, not in one burst
Written reviews rose from 0 to 6 between December 15, 2025 and July 21, 2026. The largest rise inside any single 30-day window was about 1, so the count moved in steps rather than in one burst.
Documented concerns
What needs caution2
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Headline number is a blend total, not one named ingredient
The listing uses 1 g for quercetin. The panel lists quercetin at 0.15 g; the other 850 mg is the rest of the listed blend. Panel addition: Beta-Nicotinamide Mononucleotide 500 mg + Trimethylglycine 250 mg + Quercetin (from Sophora japonica Bud Extract) 150 mg + Resveratrol (from Polygonum cuspidatum Root Extract) 100 mg = 1,000 mg. This documents the framing; it does not establish what is inside the product.
The listing says 1,000 mg of quercetin; the panel says 150 mg
We could not find an explanation for the difference — no blend, extract ratio, compound form or multi-capsule serving accounts for it. You are getting 150 mg of quercetin per serving. Worth asking the brand which number describes the capsule you swallow.
Unresolved public record
What is still missing7
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Label math withheld — variant ambiguity
Multi-pack listing (pack of 3) — the stated weight may cover all packs, so per-serving mass can't be pinned. Arithmetic runs only when every number provably belongs to the same product size.
Listing and photo-read panel need confirmation
The listing says 1 g, while our photo read produced Quercetin (from Sophora japonica Bud Extract) at 150 mg per serving. OCR can confuse small units and digits, so this remains unresolved until checked against the physical label.
“Lab tested” claimed, but no lab or report named
The observed listing and a related brand product page both claim third-party testing. Neither names the laboratory or links a product- or lot-specific report. The related page does not publish this record's UPC. Repeating the claim across two pages confirms the brand publishes it, not that testing occurred. NSF, IFOS, USP, and Informed-Sport were not checked in this record.
Research context is available for the listed ingredients
Published sources describe how NMN have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: PubMed search: nicotinamide mononucleotide human trial, ClinicalTrials.gov — NMN.
No recall found — which is not the same as being tested
This means only that no enforcement record matched the brand name — it does not mean the product was tested, reviewed, or cleared by FDA. New and untested products also have no recall records.
This item belongs to a catalog variation family
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
180-day review-count history is on file
Exact-listing history records written-review counts from 0 on 2025-12-15 to 6 on 2026-07-21 (net +6). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What to ask and check
What would settle the open questions
Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.
Ask the brand or seller
1
Answered by the panel: 0.15 g of the 1 g headline is quercetin. Which independent lab can confirm that amount in this product?
The panel resolves the front-label arithmetic. The remaining question is lot-specific contents and stability; published category testing gives context, not a test of this product.
2
Can you send the certificate of analysis (COA) for the lot number on my bottle?
A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.
3
What is the product’s UPC or GTIN?
The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.
4
Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?
Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.
5
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.
Check for yourself — no one’s permission needed
1
Compare the panel on the bottle in your hand to the one shown in this record.
Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.
2
Check the lot number and expiry on the bottle against any COA you’re given.
A certificate that doesn’t name your lot doesn’t describe what you’re holding.
These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
What the listing promises — claim by claim
Why is this shown?
A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…Resveratrol – Supports Cellular Energy & NAD+ Levels – 180 Capsules – Third-Party Tested - 3 Pack…” | Claimed, not verifiable We looked for: the observed listing, saved brand product page, any linked COA or test report; NSF, IFOS, USP, Informed-Sport were not queried | No named laboratory or lot-specific certificate was found for this exact product. A related brand page repeats a testing claim but names no issuer; its UPC is not published. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur. |
| Manufacturing claim “…GMP FACILITY…” | Partly supported We looked for: the facility registration or certificate behind the claim | “GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check. |
| Origin claim “…MADE IN THE USA FROM GLOBALLY SOURCED INGREDIENTS: Manufactured and packaged in the United States from globally sourced ingredients.…” | Claimed, not verifiable We looked for: customs records or label filings showing where ingredients were sourced and where it was made | “Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product. |
| Benefit claim “…Resveratrol – Supports Cellular Energy & NAD+ Levels – 180 Capsules – Third-Party Tested - 3 Pack…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed. |
“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.
This label vs. the doses studied
Why is this shown?
An ingredient can be well-studied at one amount and barely studied at the amount in your bottle. This lines the label up against the doses researchers actually used. It answers ‘are these the same numbers?’ — never ‘should you take this?’
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Beta-Nicotinamide Mononucleotide | shaded = doses used in studies (250 mg–1 g) · bar = this label | 500 mg — within the studied range |
Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.
