GenuinePurity NMN scores 9.3/10 on WellnessChecked. It contains 500mg of NMN per serving — matching the doses used in published human clinical trials — with independent third-party Certificates of Analysis confirming actual content and purity. A 30-day money-back guarantee is included.

Why Dose Verification Matters for NMN

The NMN market has significant quality variation. Third-party testing has revealed that many commercial NMN products contain significantly less than their stated dose, or have degraded due to improper storage. GenuinePurity publishes Certificates of Analysis from independent laboratories — confirming actual NMN content and purity for each batch.

GenuinePurity NMN vs NMN-H

GenuinePurity NMN uses standard NMN at 500mg. GenuinePurity NMN-H uses the hydrogenated form — more stable under real-world conditions. Both are dosed at 500mg with third-party testing. NMN-H is our preferred choice for consistent potency over time.
