Does the marketing hold up?
Ingredient amounts are hidden inside “Proprietary Blend Coenzyme Q10 (as ubiquinol), Glutathione (”. A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.

The public sources did not settle the marketing promises on this label.
◐Partly confirmed2
“NMN NAD+ SUPPORT: Core ingredient, Beta-Nicotinamide Mononucleotide, is a premium high-efficiency NAD+ precursor delivered at a potent 1000mg”
Evidence →Published research exists for ingredients in this formula. 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.
?Couldn’t verify independently1
“PARTY”
Evidence →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.
We looked and found no public proof. That does not count against the 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 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.
