High-Quality Whey Protein: Klean Isolate

Klean Isolate is an NSF Certified for Sport supplement that provides 20 grams of high-quality whey protein isolate per serving. Without any added flavorings or sweeteners, Klean Isolate whey protein powder can be easily incorporated into any beverage to enhance daily protein and amino acid intake.

Contains BCAAs: Fueling Muscle Building

The protein in Klean Isolate supplies essential amino acids, including branched-chain amino acids, which participate in various metabolic and physiological systems that aid in muscle building. Protein turnover in the body is continuous and can be substantial, and the rebuilding of skeletal muscle that is broken down during exercise is critically important for athletes. Essential amino acids must be provided, as they cannot be synthesized by the body.

Naturally Occurring Electrolytes: Hydration Support

Whey protein isolate also contains naturally occurring electrolytes, such as sodium and potassium, to help replenish the hydration lost during physical activity.*

Klean is Clean: Third-Party Certified for Sport

Klean Athlete products are GMO-free and formulated without wheat, gluten, or artificial coloring, flavoring, or sweeteners. Every product is third-party certified by NSF International's NSF Certified for Sport program, helping athletes, coaches, and trainers make informed decisions when choosing sports supplements.
