Their dietary supplement testing division operates ISO/IEC 17025 accredited laboratories that test products against NSF/ANSI 173, the only American National Standard for dietary supplement ingredients. NSF tests for label accuracy, contaminant screening (heavy metals, pesticides, mycotoxins, microbial), and banned substances through their Certified for Sport program. NSF is widely recognized by retailers and regulators — many major retail chains require NSF GMP certification as a baseline for supplement listing. Their lab network spans North America, Europe, and China, with ingredient testing available through their Shanghai facility for brands sourcing from Asia. NSF also operates the GMP facility certification program that many contract manufacturers pursue.
