L-Leucine

L-Leucine is one of the three essential branched-chain amino acids (BCAAs) and is widely recognized for its key role in muscle growth, repair, and recovery. As a vital trigger for muscle protein synthesis, L-Leucine is highly valued in sports nutrition, bodybuilding, and performance supplements. Since the body cannot produce it naturally, it must be obtained through diet or supplementation to support optimal muscle health and athletic performance.
