    What is amino spiking?

    Amino spiking is the practice of adding low-grade amino acids to a protein powder supplement.

    Are protein shakes “good” for you?

    Protein shakes can be an excellent addition to a well-rounded diet and healthy lifestyle. Research has shown that supplementing with protein can support athletic performance, post-workout recovery, muscle maintenance, and muscle growth.

    Can protein shakes support weight gain?

    Protein shakes may support weight gain if they contribute to a calorie surplus in your diet.

    Are protein shakes "good" for women?

    Supplementing with protein is as beneficial for women as it is for men in supporting muscle growth and maintenance, recovery, and performance.

    How can protein supplements benefit my muscles?

    Protein supplements provide the nutrients your body needs to stimulate muscle protein synthesis and support recovery post-workout.

    Frequently Asked Questions

    What is whey protein isolate?

    Whey protein isolate (WPI) has the highest concentration of protein and BCAAs, while having less carbs, cholesterol, and fat compared to other whey proteins. WPI is also low in lactose and easy on your digestive tract.

    What is hydrolyzed whey protein isolate?

    Hydrolyzed whey protein isolate (HWPI) is whey protein isolate that has been broken down into smaller chains of amino acids called peptides. Peptides are easier to digest, allowing for faster absorption into the bloodstream.

    What are BCAAs?

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

    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.
