Ingredients
L-Leucine
L-Leucine is one of the three essential branched-chain amino acids. It is sometimes referred to as the "main BCAA" for its robust role in stimulating the body's muscle protein synthesis processes by activating the mTOR signaling pathway.* It may help support the maintenance and retention of lean muscle tissue, particularly among aging adults.* Some studies also suggest leucine may support muscle endurance during exercise.*
