“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.

Partly confirmed1

“pepper extract can effectively increase the bioavailability and increase the absorption rate of the main components( NMN and”

Ingredient evidence exists; on dose: label claims 500 mg/serving — within the range commonly used in research (human trials to date mostly use 250–1,000 mg/day).

Ingredient research can support context, but it is not a trial of this exact product.

Claimed without support found1

“NMN Complex 1150mg Per Serving, NMN 500mg + Trans-Resveratrol 600mg, 99% Purity for Max Absorption, Fast-Acting & Powerful Antioxidant for NAD+,…”

We found no study of this product measuring the stated outcome over the stated timeframe.

?Couldn’t verify independently1

“your body and your mind at PEAK condition Tested for quality, safety, and efficacy: Third party lab tested for Trans-Resveratrol and NMN”

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?

Listing claim matches the Supplement Facts panel

The label promise and the Supplement Facts amount agree.

Evidence and sources

The listing claims 500 mg; the photo-read Supplement Facts panel shows NMN (Nicotinamide Mononucleotide) at 500 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.

CheckedCan you trust the review pattern?

Reviews rose from 0 to 50 between May 14 and August 25, 2026 — no sudden jump.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 0 to 50 between May 14 and August 25, 2026. The largest rise inside any single 30-day window was about 24, so the count moved in steps rather than in one burst.

Research behind the findings

Dose and research context

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

Dose vs research

NMN

500 mg per serving — within the 250–1000 mg/day used in the linked studies.

Linked ingredient research · label amount, not a recommendation
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 500 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.
