High-Purity NMN. Tested for What Matters. Fully Transparent.
Produced using clean, enzymatic synthesis, our NMN is tested to achieve ≥99% purity with strict control over contaminants. Heavy metals—including lead, arsenic, cadmium, and mercury—are verified to be below 0.1 ppm.
Every batch is documented, with Certificates of Analysis (COAs) publicly available for complete transparency.
Each NMN batch is verified at 99% purity using 1H-NMR analysis, ensuring a highly refined and reliable ingredient.
Each batch is tested for heavy metals (ICP-MS), microbiological quality (Ph.Eur.), non-irradiation, GMO-free status, and allergen absence — ensuring clean, safe, and reliable NMN.
Final manufacturing and bottling in the Netherlands in FSSC 22000 certified facilities — ensuring controlled production, safe handling, and rigorous food safety management.
Manufactured through enzymatic synthesis rather than conventional chemical reactions. This targeted process minimizes residual solvents and impurities, producing a cleaner, more stable, and higher-quality NMN.
Premium Longevir™ NMN produced in Lithuania in ISO 22000 and ISO 13485 certified facilities, and audited for compliance with FDA 21 CFR Part 111 cGMP — ensuring exceptional purity, safety, and full traceability.
Gluten, soy, milk, nuts, fish, crustaceans, and molluscs are confirmed absent through batch allergen testing.

Global Trust -Customers Around the World
“After a few weeks of consistent use, I noticed more stable energy throughout the day and better focus without crashes. It’s become a simple part of my daily routine, and I plan to continue using it long-term”
“I was hesitant at first and didn’t notice much in the beginning. But after sticking with it for a while, I realized I felt more resilient day to day and less run down by the evening. It’s subtle, but it adds up.”
"I have taken NMN from a different brand in the past but stopped because I wasn't sure if I could trust their ingredients. However, since Celvity is quite transparent, I decided to give it a try and so far I am happy with it."
