L-Leucine
L-Leucine is an essential branched-chain amino acid (BCAA) crucial for muscle protein synthesis, muscle growth, and recovery. It plays a key role in stimulating mTOR, the pathway responsible for muscle building, making it one of the most important amino acids for athletes and fitness enthusiasts. L-Leucine also helps reduce muscle breakdown, supports energy production during exercise, and enhances endurance, allowing individuals to train harder and recover faster
