Trilogy BCAA Capsules features a combination of the essential amino acids leucine, isoleucine and valine. The combination of these three essential amino acids make up approximately one third of skeletal muscle in the human body and play an important role in protein synthesis and thus may assist in the support of muscle growth and repair. Our formulation also contains Alpha Lipoic acid. Lipoic acid is critical in glycolysis and in the Krebs cycle, two complex biochemical processes essential for the generation of cellular energy. Lysine is also an essential amino acid that is a necessary building block for all protein and assists in building muscle proteins.
