Premium Casein Protein

CaseinOne uses 100% Micellar Casein protein to make one of the best slow-digesting proteins on the market today.


  • BUILD MUSCLE: Did you know you can build muscle while sleeping? This slow-release protein powder is loaded with amino acids which support muscle growth while you sleep. Give your muscles what they need to grow, give them CaseinOne!
  • NO AMINO SPIKING: When we say our protein is made with 100% micellar Casein we mean it! Every scoop contains 23g of pure protein, without any free-form amino acids to increase the protein content.
  • SLOW DIGESTING: CaseinOne is made from 100% Micellar Casein Protein, which means it promotes a sustained amino acid release. This sustained release makes CaseinOne protein powder perfect for taking before bed to ensure your muscles are being fed to grow while you sleep!
  • MUSCLE RECOVERY: Not only is this protein delicious but it also helps to repair and build lean muscle while preventing muscle breakdown. Casein Protein is well known for being a slow-digesting high-quality protein powder. Recover faster by giving your muscles the nutrients they need!
  • PREMIUM INGREDIENTS: Our protein is made using Good Manufacturing Practices, so you get a safe, all-natural protein powder.
