    Frequently Asked Questions

    What is micellar casein protein?

    Micellar casein is a milk protein that is digested more slowly than other proteins, providing an extended release of muscle-building amino acids that help prevent catabolism.

    What is catabolism?  

    Catabolism is the breakdown of protein. When your body goes for extended periods without food, or when it’s under significant metabolic stress during exercise, it can resort to catabolizing your muscles for energy.
