Testing & quality
Kion says its supplements are made in a cGMP facility that is NSF certified and that third-party finished-product testing checks identity, purity, microbes and contaminants. It publishes no certificates of analysis, and NSF's Certified for Sport database lists no Kion products. A 2020 California Prop 65 settlement over lead covered three other Kion products, not Aminos.
