Does the marketing hold up?

Testing claimed — documentation not found. The observed listing and the exact brand product page both claim third-party testing. Neither names the laboratory or links a product- or lot-specific report. …

“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Marketing claims, checked

The checks, one by one

The public sources did not settle the marketing promises on this label.

Partly confirmed2

“GMP”

“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

Evidence →
“NMN Supplement (5-in-1) NAD+ Booster with Resveratrol - Cellular Energy, Focus & Healthy Aging Support for Men and Women - Mitochondria Formula w…”

Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.

?Couldn’t verify independently2

“NMN Supplement (5-in-1) NAD+ Booster with Resveratrol - Cellular Energy, Focus & Healthy Aging Support for Men and Women - Mitochondria Formula w…”

“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.

Evidence →
“Tested”

No named laboratory or lot-specific certificate was found for this exact product. The exact brand page repeats a testing claim but names no issuer. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.

Evidence →

We looked and found no public proof. That does not count against the product.

Quick read · 3 useful findings

What is worth knowing.

Headlines first. Open evidence only when you want the source trail.

CheckedIs the label honest?

Every ingredient shows its amount · 3 ingredients listed.

Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

Evidence and sources

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

CheckedWho is behind it?

The barcode identity checks out · 199874280172.

The barcode matches, so we are checking the right product rather than a look-alike.

Evidence and sources

The brand's store lists this exact barcode as “NMN Supplement (5-in-1) NAD+ Booster with Resveratrol - Cellular Energy, Focus & Healthy Aging Support for Men and Women - Mitochondria Formula w Fisetin, Astaxanthin, Olive Leaf, Vegan, Made in USA” (variant: Default Title)…

Locked evidence record →Open the full source-linked finding
CheckedCan you trust the review pattern?

We can see 2 of this product’s 32 reviews — the count rose between June 23 and June 29, 2026. That is too small a slice to say anything about the wider pattern.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 30 to 32 between June 23 and June 29, 2026. The largest rise inside any single 30-day window was about 2, so the count moved in steps rather than in one burst.

What remains open 3
  • No FDA recall matched this brand in the current search.
  • We have not found a public label filing for this exact product.
  • Barcode checksum is valid; no independent product record was found.

These are evidence gaps, not strikes against the product.

Research behind the findings

Dose and research context

The label amount is shown beside the range used in the linked ingredient studies.

Dose vs research

NMN

300 mg per serving — within the 250–1000 mg/day used in the linked studies.

Linked ingredient research · label amount, not a recommendation
Background reading

What the research says about these amounts

Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.

The panel lists 300 mg of NMN (nicotinamide mononucleotide) per serving. Studies we found used 250 mg–1 g a day, so this sits inside that range.

0studied 250 mg–1 g

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.

Same UPC/GTIN observed across 2 sellers. Amazon was lowest at $21.99; Brand website was highest at $34.99 — a $13.00 range at check time.

The observed listing and exact brand page repeat 300 mg. That confirms cross-page consistency of the published claim, not the product contents.

Reference prices only · no affiliate links · every compared seller must publish the matching UPC/GTIN.
