Does the marketing hold up?
Every ingredient shows its amount · 1 ingredients listed. Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
“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 confirmed3
“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.
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.

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.

Dose and research context
The label amount is shown beside the range used in the linked ingredient studies.
NMN
1000 mg per serving — within the 250–1000 mg/day used in the linked studies.
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.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
