Do you take them? Branched-Chain Amino Acids (BCAAs)—leucine, isoleucine, and valine—are essential nutrients that play a critical role in fitness and muscle recovery. Unlike other amino acids, BCAAs are metabolized directly in the muscles, making them a quick energy source during workouts. They help reduce muscle soreness, support muscle growth, and prevent muscle breakdown, especially during intense training or calorie deficits. Incorporating BCAAs into your routine can enhance endurance, promote faster recovery, and optimize your performance, making them a valuable tool for anyone pursuing fitness goals.
