BCAA stands for Branched-Chain Amino Acids.
Explanation:
Branched-Chain Amino Acids (BCAAs): These are a group of three essential amino acids: leucine, isoleucine, and valine. They are considered "essential" because the human body cannot produce them, meaning they must be obtained through diet or supplementation.
Role in Fitness: BCAAs are popular in the fitness community, particularly among athletes and bodybuilders, as they are thought to play a role in muscle protein synthesis, muscle recovery, and reducing muscle fatigue. The "2:1:1" ratio often seen on BCAA supplements, like the one in the image, typically refers to the ratio of leucine to isoleucine to valine.
