Branched Chained Amino Acids (BCAA's) are a group of amino acids. The amino acids in the group are leucine, isoleucine and valine. BCAA's are three of the nine essential amino acids that humans need. They are also almost half of the amino acids needed by mammals.


BCAA's are great for anyone who is interested in gaining muscle mass. This is because the amino acids found in BCAA's make up one third of the amino acids necessary to build muscle. Anyone who is interested in gaining muscle mass should consider using BCAA supplements to aid in that endeavor. BCAA's can also be used for those who are trying to lose fat by cutting calories, while still preserving muscle mass. This is because BCAA's help preserve lean muscle when cutting calories.


BCAA's work by setting the foundation for muscle growth. This is because they have one third of the amino acids necessary to increase muscle mass. These amino acids also help prevent catabolism (muscle mass being used for energy) while dieting. This is why many in the fitness industry use BCAA's when preparing for any type of fitness competition.
