Medically reviewed by Melissa Nieves, LND Valine is one of three branched-chain amino acids (BCAA), compounds the body requires to create and maintain proteins, brain chemicals, and hormones.

WebMD explains the uses and risks of the supplement branched-chain amino acids, sometimes used by athletes to prevent muscle breakdown during workouts.

The nine essential amino acids are critical for many functions in your body, and some people take them in supplement form.

Some products, however, zero in on just the three branched-chain amino acids (BCAAs)—leucine, isoleucine, and valine—because of their potential role in muscle building and recovery.

Nine essential amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—are available only through foods or supplements.

Dissolvable glass made from amino acids can be used to create 3D-printed components that aren’t harmful to organisms – they could one day be used to make medical devices that dissolve in the ...

BCAAs are essential amino acids. The three BCAAs are leucine, isoleucine, and valine. The body uses amino acids to make proteins, which are the building blocks of every cell, tissue, and organ.

How Do I Choose an Amino Acid Supplement? Select a product with all nine essential amino acids: leucine, isoleucine, valine, histidine, lysine, methionine, phenylalanine, threonine, and tryptophan.

Of 20 plasma amino acids measured, valine, leucine, isoleucine, tyrosine and phenylalanine were increased, and glycine decreased, in obese subjects compared with age- and sex-matched controls. The ...
