What are Branched Chain Amino Acids?

There are 20 amino acids that make up muscle protein (or muscle tissue). Of those, nine are essential (the body cannot make them, we need to get them from our diet) and 11 are non-essential (the body can make them). Out of the nine essential amino acids, three are known as branched chain amino acids: leucine, isoleucine, and valine. These three amino acids are thought to have a special role in increasing performance. Read More
