L-Valine is one of the three essential branched-chain amino acids (BCAAs), known for its role in muscle repair, endurance, and energy balance. It works alongside L-Leucine and L-Isoleucine to support muscle metabolism, reduce exercise-related fatigue, and aid in recovery. As the body cannot produce L-Valine naturally, it must be obtained through diet or supplementation, making it a key ingredient in sports nutrition and wellness products.
