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.
Every check we ran
Nmn dose matches published studies
label claims 500 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.
Intake method matches the research
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.
Each ingredient’s 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.
No data yet: Listing and photo-read panel need confirmation
The listing says 500 mg, while our photo read produced NMN at 100 mg per serving. OCR can confuse small units and digits, so this remains unresolved until checked against the physical label.
Reaching a studied dose costs about $13/month
At 1.0 serving(s) a day to reach the low end of the studied range (250–1000 mg), this product runs roughly $13 per month. A price observation, not a recommendation.
Not found in NIH's DSLD label registry
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
UPC valid, no independent record
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
180-day review-count history is on file
Exact-listing history records written-review counts from 13 on 2026-01-26 to 105 on 2026-07-16 (net +92). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Speed-of-results claim “Sublingual NMN 500mg, Max Absorbency & Fast-Acting NMN Supplement（120-Day Supply）, 99% Pure NMN…” | No evidence located We looked for: a study measuring the stated outcome over the stated time | No study measuring the stated outcome over the stated timeframe was located for this product. |
| Benefit claim “…outh and under the tongue, which can greatly increase the bioavailability of NMN and enhance the m…” | 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 500 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
Why is this shown?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| NMN | shaded = doses used in studies (250 mg–1 g) · bar = this label | 100 mg — below 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.
