Our NMN Boost is manufactured in the United States in an GMP-certified, FDA-approved facility. For competitive reasons, we don't divulge our US-based manufacturing partners.
Our NMN is third-party tested by an independent lab demonstrating high purity (>99 percent) of our NMN, and has been tested for contaminants like lead, arsenic, cadmium and mercury.
