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.
The listing-image panel publishes 1 separately quantified row and 3 combined blend totals. Ingredients inside a blend do not have separate amounts.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| NMN (β-nicotinamide mononucleotide) | 300 mg | — | |
| Resveratrol Elite™™ Proprietary Blend providing 18% trans-resveratrol (10 mg) [from Japanese knotweed (root)], 35% galactomannans (19 mg) [from fenugreek (seed)] | 55 mg | — | |
| Bio-Quercetin® Proprietary Blend providing 35% quercetin (5 mg) [from Japanese sophora concentrate (flower bud)], 30% galactomannans (4 mg) [from fenugreek (seed]) | 14 mg | — | |
| Bio-Fisetin® Proprietary Blend providing 18% fisetin (0.4 mg) [from wax tree extract (stem)], 35% galactomannans (0.77 mg) [from fenugreek (seed)] | 2.22 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; the open question is whether those listed amounts are independently verified and how they compare with relevant research.
vision:google/gemini-flash-1.5 Amounts are shown as listed panel data, not independently lab-tested contents.
Every check we ran
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
USPTO lists Life Extension Foundation, Inc. (CORPORATION) in FLORIDA, USA 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 grew from 0 to 20 across 2026-06-07 – 2026-07-23 with no single manufactured spike (largest 30-day gain ~17).
Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
We read the full Supplement Facts panel from the listing-image panel (below), but the label doesn’t state a serving weight, so the arithmetic can’t run. A gap in the label’s information, not evidence of a problem.
Published sources describe how fenugreek, 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: fenugreek extract randomized controlled trial, NIH NCCIH — Fenugreek.
This record does not currently hold an matched to this exact product public label filing for the exact product. That is a LookCloser coverage gap, 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 2026-06-07 to 20 on 2026-07-23 (net +20). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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
Which specific study supports this claim — and was it run on this exact formula?
Ask for the citation, how many people took part, the dose used, and whether the study tested this product or just one ingredient in it. Ingredient research is not product evidence.
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.
What is the amount of each ingredient inside the proprietary blend?
A blend total tells you nothing about whether any single ingredient reaches a dose used in research. Brands may decline — that answer is informative too.
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 737870255994.
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 |
|---|---|---|
| Clinical-evidence claim “…tion. NMN is a direct NAD+ precursor that is clinically studied to increase NAD+ levels in the bloodstream.…” | No evidence located We looked for: a named, citable clinical study of this product or formula | We found no named, citable study of this product or formula. The claim may rest on ingredient research rather than a trial of this product. |
| Origin claim “…of our products are non-GMO, gluten-free and manufactured in the USA with internationally sourced ingredients—and…” | Claimed, not verifiable We looked for: customs records or label filings showing where ingredients were sourced and where it was made | “Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product. |
| Benefit claim “…ps Replenish NAD+ levels – In the body, NAD+ promotes healthy aging and cellular energy production…” | 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
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Resveratrol Elite™™ Proprietary Blend provid | shaded = doses used in studies (500 mg–600 mg) · bar = this label | 55 mg — below the studied range |
| NMN (β-nicotinamide mononucleotide) | shaded = doses used in studies (250 mg–1 g) · bar = this label | 300 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.
