Scientist Emil Fischer isolated Valine from Casein in 1901 by protein hydrolysis. Today, Valine is recognized as an essential branched-chain amino acid that plays a role in stimulating growth. Valine, along with Leucine and Isoleucine, is a trio of branched-chain amino acids that make up more than 2/3 of the total amino acids in the body, playing an invaluable role for humans.

Leucine, Isoleucine, and Valine are branched-chain amino acids (BCAAs). They form an important group of amino acids. Of these, Leucine is the most well-studied because its oxidation rate is higher than that of Isoleucine or Valine.

Amino acids are the building blocks of protein. Supplementing essential amino acids daily can help improve physical health, muscle strength, and mood. There are 9 different essential amino acids, but all provide many benefits to the body.
