Checked against public sources on July 25, 2026 · LookCloser does not sell or recommend supplements.
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 public sources did not settle the marketing promises on this label.
Published research exists for ingredients in this formula — see Related research below. Whether this product’s doses match those studies could not be confirmed.
“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.
Ingredient research can support context, but it is not a trial of this exact product.
“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.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

The label amount is shown beside the ranges used in the linked ingredient studies.
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 250 mg 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.
