Does the marketing hold up?

FDA recall appears in this brand's history An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

“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

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

“nut or sesame ingredients. Produced in a GMP facility that processes other ingredients”

“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.

FDA recall appears in this brand's history

An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

Checks outIs 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.

What remains open 4
  • No matched to this exact product public label filing is saved in this record.
  • Brand ownership is not settled in this record.
  • Barcode checksum is valid; no independent product record was found.
  • No dated review-history series is on file yet.

These are evidence gaps, not strikes against the product.

Research behind the findings

Dose and research context

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

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 250 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.
