This product can't be verified from public data Neither good nor bad — the checks below show what this listing publishes and what it withholds. Verifiable products publish more. Evidence availability only; this does not establish safety or effectiveness.
2 of 6 public trust signals found · 1 product-specific concern · $1.33 per serving
This product lists four active ingredients: NMN, Quercetin, TMG, and Resveratrol, which together total 1,000 mg per serving. The listing claims it is third-party tested, but doesn't name the laboratory, so this specific claim cannot be verified. You can check if the brand's certification for NSF/ANSI 173 covers this exact product by looking up "Cata-Kor NMN 4-in-1 Complex" on NSF’s certified products registry.
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Nothing in this listing contradicts how these ingredients were studied (NMN). For example, NMN: trials report raised NAD+ blood markers; whether that produces anti-aging or energy outcomes people care about remains unsettled in humans. Sources: PubMed search: nicotinamide mononucleotide human trial, ClinicalTrials.gov — NMN.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Marketplace rating 4.5★ across 1,194 ratings. Authenticity not analysed: burst, purge and stockout patterns need price/review history.
Technical check only: the panel’s 4 actives sum to 1,000 mg, which fits inside the ≈2,000 mg serving. This means the numbers are physically possible — it does not mean the formula was validated or the contents confirmed.
What to ask and check
Ask the brand or seller
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.
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.
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.
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
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.
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.

Want to know if this changes?
Supplements are repeat purchases. Formulas get reformulated, lots get recalled, brands finally publish the lab report they were asked for. We can watch this record and email you only if something changes.
Your address is used for this one purpose. No newsletter, no marketing, no third parties, no tracking pixels — and every email carries a one-click unsubscribe that needs no login. We store the address, the record, and the date. Nothing else.
