Does the marketing hold up?

Testing claimed — documentation not found. The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is saved, so the claim cannot be verified as stated. …

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.

Marketing claims, checked

The checks, one by one

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

Partly confirmed1

“NAD⁺”

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 independently1

“tested in”

No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. 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.

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 mg of NMN (nicotinamide mononucleotide) per serving. Studies we found used 250 mg–1 g a day, so this sits below 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.
