Every ingredient shows its amount · 1 ingredients listed. Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

“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

“Life Extension NAD+ Cell Support NMN, Healthy Aging, Energy Support, nicotinamide mononucleotide, NAD+, 300 mg, Gluten Free, Non-GMO, Vegetarian, 90”

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.

Claimed without support found1

“formula contains a direct NAD+ precursor clinically studied to increase NAD+ levels in the”

We found no named, citable study of this product or formula. The claim may rest on ingredient research rather than a trial of this product.

?Couldn’t verify independently1

“majority of our products are non-GMO, gluten-free and manufactured in the USA with internationally sourced ingredients—and a Certificate of…”

“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.

Evidence →

We looked and found no public proof. That does not count against the product.

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.

CheckedCan you trust the review pattern?

Reviews rose from 0 to 24 between June 24 and August 12, 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 24 between June 24 and August 12, 2026. The largest rise inside any single 30-day window was about 16, so the count moved in steps rather than in one burst.

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.
