Klean Athlete Klean Isolate Natural Chocolate Flavor useful for athelets who require amino acids for muscle integrity. Provides 20 grams of Whey protein Isolate in each serving.

The dynamics of this constant degradation and re-synthesis demand a daily supply of dietary protein and their constituent amino acids. Essential or indispensable dietary amino acids must be supplied by the diet as they are not synthesized by the body Klean Focus is tested and certified by the NSF Certified for Sport Program, which was created to meet the growing demands of athletes, coaches and healthcare professionals to certify that sports supplements are safe and completely free from banned substances. Every product that carries the NSF mark has undergone stringent laboratory testing to confirm content, purity and compliance.
