Calm and Cool, though specially formulated for calves or horses, respectively, each contain a special blend of herbs and the amino acid "L-Tryptophan."  L-Tryptophan is an "essential" amino acid, meaning that it is essential to life and cannot be synthesized by the body.  L-Tryptophan, of all the essential amino acids, is the least abundant in typical animal feeds.  Therefore, it is often lacking in the diet and must be supplemented.  L-Tryptophan is essential to the proper functioning of the nervous system.
