Tryptophan is an amino acid that is made from plant or animal sources.
It is known as an "essential" amino acid because the body does not produce it. Tryptophan is important to the functions of many organs in the body.

When you consume tryptophan, your body absorbs it and changes it to eventually become a hormone called serotonin. Serotonin transmits signals between your nerve cells and also narrows (constricts) blood vessels. The amount of serotonin in the brain can affect mood.
