L-Glutamine is a non-essential amino acid. It is very abundant (it makes up almost 2/3 of the amino acids that make up muscle protein) and is widely used by muscles, but is produced in limited quantities by the human body. It is therefore important to ensure an adequate intake of food and, if necessary, food supplements. Athletes who train particularly hard should consider supplementing their diet with L-Glutamine 6000 for best results.
