BCAA stands for Branched Chain Amino Acids, which are essential amino acids that are metabolized by the body and used as sources of muscle energy. The three amino acids that make up BCAA are valine, leucine, and isoleucine. BCAA supplements have been shown to have several benefits, including building muscle, decreasing muscle fatigue, and alleviating muscle soreness. They have also been used to prevent muscle breakdown during exercise and support liver health. BCAA is found in protein-rich foods such as meat, eggs, and dairy products. While BCAA supplements are generally safe when taken for up to 6 months, they may interfere with blood glucose levels during and after surgery, and should be avoided by pregnant or breastfeeding women.
