What is BCAA?
BCAA stands for branched-chain amino acids, consisting of 3 types of BCAA branched amino acids: leucine, isoleucine, and valine.
These 3 amino acids are closely linked together in the formation of protein molecules. Not only that, but BCAAs also play an important role when building muscle mass for the body.
In the human body, there are up to 20 different amino acids to make up different protein molecules. Among them, the body can synthesize up to 11 amino acids, the remaining 9 amino acids cannot synthesize but need a reasonable diet. Among those 9 essential amino acids, 3 are BCAA branched-chain amino acids (leucine, isoleucine, and valine).
