Compliance varies significantly by destination. For the U.S. market, while NMN's status as a dietary supplement is currently under FDA review, many buyers still look for GRAS (Generally Recognized as Safe) status. For the EU market, ensure the product complies with EFSA (European Food Safety Authority) regulations regarding 'Novel Foods.' Always confirm that the product is Heavy Metal Tested (Lead, Arsenic, Cadmium, Mercury) and Microbiological Tested to meet the safety thresholds of the target country.
