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.
Every check we ran
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
label claims 1000 mg/serving — within the range commonly used in research (human trials to date mostly use 250–1,000 mg/day). Sources: PubMed search: nicotinamide mononucleotide human trial, ClinicalTrials.gov — NMN.
USPTO lists Lonnie Crouse (INDIVIDUAL; OTHER) in UNITED KINGDOM; CHINA 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.
Written reviews rose from 0 to 161 between December 22, 2025 and August 28, 2026. The largest rise inside any single 30-day window was about 39, so the count moved in steps rather than in one burst.
Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
No contradictions or product-specific cautions were found at this check depth.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The saved listing evidence does not establish net weight, unit count, servings per container, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.
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.
We have not found a public label filing for this exact product. That is a gap in our records, not evidence that no filing exists.
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.
Exact-listing history records written-review counts from 0 on 2025-12-22 to 161 on 2026-08-28 (net +161). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
The package says manufactured for: CFUKING, AJI Gag PK Rockville, MD 04716 United States of America. USPTO names Lonnie Crouse as the exact wordmark owner. That can be a normal distributor, manufacturer, or licensing relationship; the saved records do not establish the relationship.
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
What to ask and check
Ask the brand or seller
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.
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
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.
Scan the barcode on the package and confirm it reads 739768820000.
A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.
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
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…May Support:…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient evidence exists; on dose: label claims 1000 mg/serving — within the range commonly used in research (human trials to date mostly use 250–1,000 mg/day). |
“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
| Ingredient | Where this label sits | Reading |
|---|---|---|
| NMN (β-Nicotinamide Mononucleotide) | shaded = doses used in studies (250 mg–1 g) · bar = this label | 1 g — 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.

ℹ Use pattern in research: trials report raised NAD+ blood markers; whether that produces anti-aging or energy outcomes people care about remains unsettled in humans.
