  • Clean whey protein isolate: Fast-absorbing whey protein isolate (from milk) that provides essential amino acids for muscle-building, including branched-chain amino acids.
  • Four flavor options: Unflavored, Natural Vanilla, Natural Chocolate, and Natural Strawberry to fit any recipe or beverage.
  • No artificial sweeteners or flavors: Flavored variants use natural flavors and are sweetened with stevia and monk fruit extract.
  • Naturally contains electrolytes: Whey isolate naturally contains sodium and potassium.
  • NSF Certified for Sport: Third-party tested for content, purity, and freedom from banned substances.
  • Daily use: Mix 1 scoop into water, milk, or a smoothie, or add to yogurt, oatmeal, or recipes. Adults may take one or more scoops daily to help meet elevated protein needs, or as directed by a trainer, coach, or health professional.

Klean Isolate by Klean Athlete is a great supplement for athletes who need additional amino acids for muscle integrity. Klean Isolate supplies 20 grams of high quality whey protein isolate in each serving. Unflavored has no additional flavorings or sweeteners; flavored versions use natural flavors and stevia/monk fruit.

The dietary protein provided by Klean Isolate supplies essential amino acids that participate in many of the metabolic and physiologic systems in the body, but most importantly to an athlete is the building of skeletal muscle that is broken down during exercise.

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.

Unflavored ingredients: Whey Protein Isolate (milk). Flavored ingredients: Whey Protein Isolate (milk), natural flavor, salt, sunflower lecithin, stevia leaf extract (Rebaudioside A), monk fruit extract.

Contains: Milk. Contains no yeast, wheat, gluten, soy, corn, starch, artificial coloring, artificial preservatives, artificial flavoring, or GMOs.

Suggested Usage: As a dietary supplement, adults take 1 scoop daily mixed with 10-12 oz of water or other beverage, or as directed by a trainer, coach, or health professional.

These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.

Q: Which flavor should I choose?
A: Unflavored is the most versatile — add it to smoothies, oatmeal, or coffee without altering taste. Chocolate and Vanilla are the standard flavored options for shakes. Strawberry is a lighter alternative if you find chocolate/vanilla too heavy.

Q: What's the difference between Klean Isolate and Klean Casein?
A: Klean Isolate is fast-digesting whey protein, ideal around workouts for rapid amino acid delivery. Klean Casein is slow-digesting micellar casein, ideal before bed or between meals for sustained release.

Q: When should I take Klean Isolate?
A: Most athletes take it post-workout to deliver amino acids fast for muscle protein synthesis. Can also be used between meals or as a supplement to boost daily protein intake.

Q: Is Klean Isolate NSF Certified for Sport?
A: Yes. Every batch is tested and certified through NSF Certified for Sport, verifying content, purity, and freedom from banned substances.

Q: Is it lactose-free?
A: Whey protein isolate has very low lactose (typically less than 1%), making it tolerable for most people with mild lactose sensitivity. Not appropriate for those with severe lactose intolerance or milk allergies. Contains milk.
