L-valine is one of the 20 amino acids used to synthesize proteins in the human body, which are chemically known as proteinogenic amino acids. It is named for the valerian plant, from which valine was first derived. The DNA codons for L-valine are GUA, GUC, GUG and GUU. L-valine is non-polar and is one of three proteinogenic amino acids that have a branched chain, along with isoleucine and leucine.

L-valine is an essential amino acid, meaning that it is not able to be biosynthesized in the human body. It must therefore be obtained through dietary sources, primarily meat. Dairy products are also high in L-valine, especially cottage cheese. Vegetable sources of L-valine include cereal grains, mushrooms, peanuts and soybeans. 

The most common uses of L-valine in health supplements relates to its role in muscle synthesis and maintenance. 

Additional uses of L-valine include stress management, growth in children and support of the immune system.
