High Quality Whey Protein: Klean Isolate

Klean Isolate is an NSF Certified for Sport supplement that supplies 20 grams of high-quality Whey Protein isolate in each serving. With no additional flavorings or sweeteners, Klean Isolate whey protein powder can easily be added to any beverage to enhance daily protein and amino acid intake.

BCAAs and Protein Turnover

The protein provided by Klean Isolate supplies essential amino acids, including branched-chain amino acids that participate in many metabolic and physiologic 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 to athletes. Essential amino acids must be supplied by the diet as they are not synthesized by the body.

Naturally Occurring Electrolytes

Whey Protein isolate also contains naturally occurring electrolytes - sodium and potassium - to help replenish hydration lost during activity.

Klean is Clean

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, to help athletes, coaches, and trainers make more informed decisions when choosing sports supplements.
