Evidence →“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.

Is it the real thing?✓Barcode matches outside records
Trouble on record?✓No recalls found
“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.

The checks, one by one
The public sources did not settle the marketing promises on this label.
◐Partly confirmed2
“NAD+ AND CELLULAR ENERGY — NMN is a direct NAD+ precursor that helps support the coenzyme essential for converting nutrients into energy,…”
Evidence →Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.
Ingredient research can support context, but it is not a trial of this exact product.
?Couldn’t verify independently2
“YOU CAN TRUST SINCE 1988 — Proudly made in the USA and triple-tested for purity and potency, with every batch verified by independent third-party…”
Evidence →No named laboratory or lot-specific certificate was found for this exact product. A related brand page repeats a testing claim but names no issuer; its UPC is not published. 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.
“YOU CAN TRUST SINCE 1988 — Proudly made in the USA and triple-tested for purity and potency, with every batch verified by independent third-party…”
Evidence →“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
We looked and found no public proof. That does not count against the product.

Headlines first. Open evidence only when you want the source trail.
CheckedIs the label honest?
Every ingredient shows its amount · 1 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.

Research behind the findings
Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
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 1 g 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.

The brand-page price is shown as a shopping lead only. It is excluded from the exact-product price difference because the page does not publish this record's matching UPC/GTIN.
The observed listing and related brand page repeat 1,000 mg, 60 capsules. That confirms cross-page consistency of the published claim, not the product contents.
