BCAAs, with the full name of Branched-chain amino acids, are the general term for three common amino acids in proteins, namely leucine, valine and isoleucine. So BCAA is also called compound branched chain amino acid. BCAAs composed of three protein amino acids is one of the nine essential amino acids in humans. But the body can’t synthesize it itself, it can only be obtained from food. BCAAs fill a variety of metabolic and physiological roles. Furthermore, BCAAs share the same transporter as aromatic amino acids to enter the brain. Once in the brain, branched-chain amino acids may play a role in protein synthesis, neurotransmitter synthesis, and energy production.

  • Anti-fatigue effect. BCAA branched chain amino acids have anti-central fatigue and anti-muscle fatigue effects. This is the most important role of BCAAs. First, the supplementation of branched-chain amino acids can delay and relieve central fatigue. Second, the supplementation of branched-chain amino acids is mainly to accelerate the recovery and removal of a series of substances in the body after exercise, thereby reducing and delaying delayed onset muscle soreness.
  • Provide energy to the body. In addition to being an important component of protein in the body, BCAA supplement can also help our muscles synthesize.
  • Promote muscle synthesis. Long-term endurance exercise is particularly likely to cause muscle loss. The supplementation of BCAA supplements can promote protein synthesis, help muscle recovery, and reduce muscle damage.

    The BCAA ration refers to the ration of leucine/isoleucine/valine. Leucine plays the most important role in muscle growth. Research has shown that those who add extra leucine to their post-workout protein and carbohydrate supplements have more pronounced muscle protein synthesis. Although leucine is very good, the main effect of branched-chain amino acids is anti-fatigue. So the recommended ratio is leucine: isoleucine: valine = 2:1:1. This ratio can better play the role of BCAA amino acid.

    Why BCAAs Are Important for Bodybuilding

    BCAA act as nitrogen carrier to assist in the synthesis of other amino acids required for muscle synthesis. Simply put, it is a process by which simple amino acids synthesize complex intact muscle tissue. Therefore, BCAAs can stimulate insulin production. The main role of insulin is to allow peripheral blood glucose to be absorbed by muscles and used as a source of energy. The production of insulin also promotes the absorption of amino acids by the muscles. BCAAs are both anabolic and anticatabolic, as they can significantly increase protein synthesis, promote the release of related hormones such as growth hormone, IGF-1 and insulin. It can also help maintain a reasonable testosterone/cortisol ratio.

    Metabolically, branched-chain amino acids promote protein synthesis and turnover, signaling pathways, and glucose metabolism. Oxidation of BCAA may increase fatty acid oxidation and play a role in obesity.

    It promotes anabolism in two specific ways: promote the release of insulin and promote the release of growth hormone. 

    Simply put, anyone who wants to relieve fatigue can take BCAA supplement, especially athletes and fitness enthusiasts. General healthy people can easily get enough branched-chain amino acids in their daily food, while some high-consumption people need additional supplements.
