  • 24 g micellar casein protein per serving: Slow-digesting protein that provides a steady release of amino acids into the bloodstream, ideal for recovery and reducing muscle breakdown while sleeping.
  • Two flavor options: Natural Vanilla Custard (30.7 g scoop) and Natural Chocolate (32.9 g scoop with alkali-processed cocoa powder).
  • Naturally-occurring electrolytes: Casein naturally contains sodium and potassium to help replenish minerals lost during activity.
  • No artificial sweeteners: Sweetened with stevia leaf extract and monk fruit extract; naturally flavored with salt and xanthan gum.
  • NSF Certified for Sport: Third-party tested for content, purity, and freedom from banned substances.
  • Best taken before bed: Mix 1 scoop into 10-12 oz of water, milk, or beverage of choice, typically taken before bed to support overnight recovery and reduce muscle breakdown.

Protein powers muscle and is essential for the health, well-being, and performance of any athlete. Klean Casein Protein supplies 24 grams of high-quality protein from micellar casein in each serving. Casein is a slow digesting protein usually taken before bed to support recovery and reduce muscle breakdown while sleeping.

As a slow-digesting protein, casein has unique features that separate it from other protein products. Slow-digesting proteins provide a steadier release of amino acids into the bloodstream compared to fast-digesting proteins, such as whey isolate. Casein helps to maintain a positive nitrogen balance and supports muscle-building.

In addition, casein contains naturally occurring electrolytes (sodium and potassium) to help replenish hydration lost during activity. Whether building or repairing muscle, athletes can turn to Klean Casein Protein for support.

Vanilla Custard: Serving size 1 scoop (approx. 30.7 g) • 20 servings per container. Other ingredients: Micellar Casein, Natural Flavors, Salt, Xanthan Gum, Stevia Leaf Extract, Monk Fruit Extract.

Chocolate: Serving size 1 scoop (approx. 32.9 g) • 20 servings per container. Other ingredients: Micellar Casein, alkali processed cocoa powder, Natural Flavors, Salt, Xanthan Gum, Stevia Leaf Extract, Monk Fruit Extract.

Suggested Usage: Adults take 1 scoop mixed into 10-12 ounces of water or other beverage, or as directed by a trainer, coach, or health professional.

Q: What's the difference between Klean Casein and Klean Isolate?
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 during long gaps between meals for sustained amino acid release over several hours.

Q: When should I take Klean Casein?
A: Most athletes take it before bed to support overnight recovery. It also works well as a mid-day meal replacement or between meals when a slower protein release is preferred.

Q: Is Klean Casein 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: How is it sweetened?
A: With natural flavors, stevia leaf extract, and monk fruit extract. No artificial sweeteners, colors, or flavors.

Q: Is it gluten-free? Does it contain any allergens?
A: Klean Casein is gluten-free and GMO-free. As a dairy-derived protein, it contains milk. Not appropriate for vegans or those with milk allergies.
