Branched-Chain Amino Acids (BCAAs), including leucine, isoleucine, and valine, are crucial for muscle health and fitness. They promote protein synthesis, aiding muscle growth and repair. BCAAs reduce muscle soreness and fatigue, particularly during intense workouts. Supplementing with BCAAs before, during, or after exercise prevents muscle breakdown and enhances recovery. Whether from dietary sources or supplements, BCAAs support muscle health, exercise performance, and overall well-being for active individuals.
