Instantized BCAA 4:1:1 200 Grams (7 Ounces)

What are Branched-Chain Amino Acids? Branched-chain amino acids (BCAA) is the name given to three of the eight essential amino acids needed to make protein: leucine, isoleucine and valine. They are called branched-chain because their structure has a 'branch' off the main trunk of the molecule. The combination of these three essential amino acids makes up approximately one-third of skeletal muscle in the human body. In order to get energy, the body can actually break down muscle to get these BCAAs. Therefore, by supplying them during or after a workout, muscles and other tissues are spared from breakdown, which occurs as a natural part of metabolism.
