BRANCHED CHAIN AMINO ACIDS (BCAA) – The Stress Amino Acids Branched chain amino acids (BCAA) are essential amino acids whose carbon structure is marked by a branch point. The BCAA are valine, isoleucine and leucine. These three amino acids are critical to human life and are particularly involved in stress, energy and muscle metabolism. BCAA supplementation … Continue reading BRANCHED CHAIN AMINO ACIDS (BCCA): Valine; Leucine; Isoleucine
