Reduced Muscle Breakdown

BCAAs reduce muscle breakdown (catabolism) during calorie restriction or intense exercise by providing an alternative energy source and stimulating protein synthesis. This helps preserve muscle mass and supports recovery.

Branched-chain amino acids (BCAAs), including leucine, isoleucine, and valine, can help reduce muscle protein breakdown (catabolism) during periods of calorie restriction or intense exercise. This occurs primarily through two mechanisms: BCAAs can serve as an alternative energy source when glucose stores are depleted, and they directly stimulate protein synthesis, promoting muscle repair and growth while inhibiting protein degradation pathways. This helps preserve muscle mass and supports recovery.
