BCAA stands for Branched-Chain Amino Acids, which are a group of three essential amino acids: leucine, isoleucine, and valine. These amino acids are essential because the body cannot produce them on its own and must obtain them through the diet.

BCAAs are often used as a dietary supplement by athletes and fitness enthusiasts to help support muscle growth, reduce muscle breakdown, and improve exercise performance. They are commonly found in powder or pill form and can be consumed before, during, or after exercise.

BCAAs are thought to work by increasing protein synthesis in the body, which can help support muscle growth and repair. They may also help reduce muscle breakdown during exercise, which can lead to faster recovery times and improved exercise performance.

BCAAs are often found in foods such as meat, eggs, and dairy products, but supplementing with BCAAs can be useful for individuals who have difficulty consuming enough protein through their diet alone, such as vegetarians or vegans.
