How does casein work?

    Last Updated: June 4, 2024

    Once ingested, casein coagulates (curdles) in the acidic environment of the stomach, which is why it is digested slowly. It moves into the intestine and is broken down into amino acids that can be used to initiate and maintain the process of muscle protein synthesis. This process takes several hours, with amino acid concentrations reaching their peak around 7 hours after ingestion.[1]
