Main features: ESSENTIAL BCAAS & SELECTIVE AMINO ACIDS L-CARNITIN BIOPERINE SUGAR-FREE EXCELLENT INTER-WORKOUT AMINO MAGIC includes the essential branched-chain amino acids (BCAA), glutamine, nitric oxide (NO) precursor arginine, lysine, ornithine, taurine with the amino acid derivative L-carnitine. Branched-chain amino acids (BCAA) are a significant group of proteinogenic amino acids that account for 35% of the essential amino acids in muscle proteins. Approximately 60% of the free amino acids in the body are composed of glutamine, which can become conditionally essential under intense sports training. Arginine is the direct precursor of nitric oxide (NO) and is essential for the synthesis of creatine. This formula is designed to contribute to the metabolic demands of intensely trained muscle tissue.
