Does the marketing hold up?
The listing and related brand page both say it is tested, but neither names the lab. A related brand page repeats the marketing claim, but its UPC is not published and repetition is not independent testing evidence. A named issuer and lot-specific report would make it checkable.

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.

“Manufactured, Triple”
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 manufactured in the USA and triple-tested for purity and”
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.

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 300 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.
