“for Cellular Energy, Mitochondrial Support & Healthy Aging. USA Manufactured, Triple”
Evidence →Published research exists for ingredients in this formula — see Related research below. 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.

“ProHealth NMN Pro 1000 (60 Capsules) Clinically Studied Uthever NMN. NAD+ Precursor for Cellular”

“& Healthy Aging. USA Manufactured, Triple Lab-Tested POWERED BY UTHEVER NMN - The world's first”
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.
“QUALITY YOU CAN TRUST SINCE 1988 - Manufactured in the USA in GMP-certified facilities, triple-tested”
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.

The label shows a visible consistency problem
Check this exact wording or duplicate row on the package before relying on the printed amount.
Evidence and sources
The label visibly shows: “Β-Nmn appears more than once”. This is a specific printing or product-image inconsistency worth checking on the package.

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 1 g 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.
