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 150 mg nmn (β-nicotinamide mononucleotide) claim matches the panel
MARKETING150 mg — per-serving claim
PANELNMN (β-Nicotinamide Mononucleotide) 150 mg — same amountNMN (β-Nicotinamide Mononucleotide) 150 mg
matches panelWe did the comparison: the listing claims 150 mg of nmn (β-nicotinamide mononucleotide), and the listing-image panel shows 150 mg nmn (β-nicotinamide mononucleotide) 1 capsule. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| NMN (β-Nicotinamide Mononucleotide) | 150 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 out1
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Documented concerns
What needs caution1
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Dose is lower than studies used
label claims 150 mg/serving — below the range commonly used in research (human trials to date mostly use 250–1,000 mg/day). A lower dose is not necessarily useless — but it is not the amount the research used. Sources: PubMed search: nicotinamide mononucleotide human trial, ClinicalTrials.gov — NMN.
Unresolved public record
What is still missing8
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Review-count history: not available
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
Multiple USPTO brand-owner records are shown
USPTO returned multiple live supplement-class records for the exact brand wordmark: General Nutrition Investment Company, GNC Holdings, LLC. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
Listing claim matches the label panel
The listing claims 150 mg; the photo-read Supplement Facts panel shows NMN (β-Nicotinamide Mononucleotide) at 150 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
Cost to reach a studied dose
At 1.7 serving(s) a day to reach the low end of the studied range (250–1000 mg), this product runs roughly $39 per month. A price observation, not a recommendation.
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.
FDA recall appears in this brand's history
This recall is not about the product on this page. GNC Holdings LLC recalled a different product on April 25, 2025. FDA has since closed that case. The recalled item was “GNC Women's 30+ Vitapak, Carton of 30 Sachets. Each sachet contains four tablets and a capsule. Paper-board carton that measures 10.25 width x 3.56 height x 3.15 depth containi”. FDA recorded the reason as “Undeclared Fish allergen (parvalbumin)”. Verify at FDA’s recall database.
Public label filing not saved
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.
Barcode record is too sparse to confirm identity
Open Food Facts resolves 853913003497 to "nad NMN" (141604), but that record lacks enough exact brand/product detail to confirm or contradict this listing.
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 0.15 g headline is nmn. 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
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.
3
Why is the NMN (nicotinamide mononucleotide) amount below the dose used in published research?
There can be good answers — a more bioavailable form, a different intended use. Ask for the reasoning and any data behind 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
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
Scan the barcode on the package and confirm it reads 853913003497.
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.
3
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 |
|---|---|---|
| Benefit claim “…NAD Precursor: NMN produces NAD+, which supports healthy DNA*…” | 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 150 mg/serving — below 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?
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 |
|---|---|---|
| NMN (β-Nicotinamide Mononucleotide) | shaded = doses used in studies (250 mg–1 g) · bar = this label | 150 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.

ℹ Dosage: label claims 150 mg/serving — below the range commonly used in research (human trials to date mostly use 250–1,000 mg/day).
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.
