Branched-chain amino acids, or BCAAs, are a special group of amino acids. They are some of the most proven athletic supplements you can take. The benefits of BCAAs include less muscle fatigue, faster recovery, higher levels of other amino acids, and better protein absorption.[1] Not getting enough of them can cause muscle loss.
Do BCAAs actually do anything?
What does BCAA actually do? Research suggests that taking BCAA supplements may improve muscle mass and performance and may reduce muscle damage from exercise. BCAAs may also benefit people with liver disease. However, some research links increased BCAA levels to conditions such as diabetes, cancer, liver disease, and heart disease.

What are BCAAs and what do they do?
What Are BCAAs and How Do They Work? BCAAs are a group of three essential amino acids namely leucine, isoleucine, and valine. They play a very important part in muscle synthesis, the process by which the body repairs the damaged muscle tissue and replaces it with new (1, 2, 3).They are unique because unlike other amino acids, they are not metabolized in the liver but in the skeletal muscles ().
