Branched-chain amino acids are essential nutrients that the body obtains from proteins found in food, especially meat, dairy products, and legumes. They include leucine, isoleucine, and valine. “Branched-chain” refers to the chemical structure of these amino acids. People use branched-chain amino acids for medicine. Some people use branched-chain amino acids to prevent fatigue and improve concentration. Athletes use branched-chain amino acids to improve exercise performance and reduce protein and muscle breakdown during intense exercise. Amino acids not only build proteins but some are critical to metabolic functions and others act as precursors to neurotransmitters – the chemicals that convey messages from one nerve to another. Amino acids also act as cofactors to vitamins and minerals – not for absorption but to allow them to perform their duties correctly once they have been assimilated in you.
