Valine is a member of the branched-chain amino acid family, along with leucine and isoleucine. The three branched-chain amino acids constitute approximately 70 percent of the amino acids in the body proteins. As such, their value in the formation and maintenance of structural and functional integrity in humans is unmeasured.


What it is

Valine is an amino acid obtained by hydrolysis of proteins and was first isolated by the German chemist Emil Fischer in 1901 from casein and is not only an essential amino acid but is also a branched-chain amino acid (the others are isoleucine and leucine) found in high concentration in the muscles.


What it does

Valine is needed for muscle metabolism and coordination, tissue repair, and for the maintenance of proper nitrogen balance in the body. It is used as an energy source by muscle tissue. It has been used to treat liver and gallbladder disease. It promotes mental vigor and can calm emotions.
