Casein Protein is a slow-digesting, high-quality milk protein derived from skimmed milk. It accounts for about 80% of the protein in cow’s milk and is well-known for its sustained amino acid release, making it ideal for muscle recovery during sleep and long periods without food intake.
Compared with whey protein, which digests quickly, casein forms a gel-like structure in the stomach, resulting in a gradual and prolonged release of amino acids into the bloodstream.
