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.
What the label discloses
The listing-image panel publishes an amount for each of its 2 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| NMNHD | 250 mg per serving | — | |
| PTEROSTILBENE | 100 mg per Capsule | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “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; the open question is whether those declared amounts are independently verified and how they compare with relevant research.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
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: Label math could not be verified
The retained listing evidence does not establish net weight, unit count, per-serving dose, 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.
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.
180-day review-count history is on file
Exact-listing history records written-review counts from 101 on 2026-02-01 to 103 on 2026-05-29 (net +2). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Clinical-evidence claim “NMNH (NMN Supplement Alternative) Only Clinically Studied Ingredient - Boosts NAD+ Levels for Anti Agi…” | No evidence located We looked for: a named, citable clinical study of this product or formula | No named, citable study of this product or formula was located in public sources. The claim may rest on ingredient-level research rather than a trial of this product. |
| Benefit claim “…native) Only Clinically Studied Ingredient - Boosts NAD+ Levels for Anti Aging and Cell Regenera…” | 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 — see Related research below. 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?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| NMNHD | shaded = doses used in studies (250 mg–1 g) · bar = this label | 250 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.

Where it sells
A brand storefront was found, but no exact-product price was published or identity-bound at build time.
Brand store doublewoodsupplements.com: 197 supplement products (+6 merch items) — for comparison, single-focus brands typically carry 5–30 products; very broad catalogs are common among companies that rebrand ready-made formulas — a pattern note, not a verdict.
