Isoleucine is one of nine essential amino acids in humans (present in dietary proteins), also essential for the production and formation of hemoglobin and the production of red blood cells. It is, therefore, an important amino acid in the process of recovery from blood loss or anemia.
Also, it is one of the branched-chain amino acid (BCAA)
Leucine, isoleucine, and valine (another amino acid) are grouped together as branched chain amino acids or BCAAs. All BCAAs are essential to human life. They are needed for the physiological response to stress, in energy production, and particularly for the normal metabolism and health of muscle.These branched-chain amino acids also tend to be popular in bodybuilders and other people who focus on building physical strength, because the intake of BCAAs can reduce muscle loss and provide faster muscle recovery.
