10 Best amino acids for muscle growth (2025)

10 best amino acids for muscle growth include leucine, isoleucine, and valine, which are essential branched-chain amino acids (BCAAs) that promote protein synthesis and reduce muscle breakdown. Glutamine supports recovery and immune function, while arginine enhances blood flow and nutrient delivery to muscles. Lysine is crucial for collagen formation and muscle repair, and threonine aids in protein synthesis. Methionine contributes to muscle metabolism, while histidine plays a role in muscle recovery. Finally, phenylalanine supports neurotransmitter production, which can enhance workout performance. Incorporating these amino acids into your diet can significantly boost muscle growth and recovery.
