    Frequently Asked Questions

    What is micellar casein?

    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 is under significant metabolic stress - like during high-intensity interval or resistance training - it can resort to catabolizing your muscles for energy.

    What is the best time to take BodyTech Micellar Casein Protein?

    For the best results, this great-tasting protein powder should be enjoyed immediately upon rising, after a workout, or before you go to bed to help protect your muscles from catabolism.

    What is Aminogen?

    Aminogen is an enzyme that helps your body digest and absorb protein.

    Frequently Asked Questions

    What are BCAAs?

    Branched-chain amino acids (BCAAs) include leucine, isoleucine, and valine. They support muscle growth and reduce muscle fatigue.

    What's the difference between whey protein isolate and concentrate?

    Whey protein concentrate ranges from 70-80% protein, whereas whey protein isolate ranges from 90-95% protein. Combining whey protein isolate and concentrate results in the building blocks for metabolically active lean muscle tissue.
