L-tryptophan is an amino acid. Amino acids are protein building blocks. L-tryptophan is called an "essential" amino acid because the body can't make it. It must be acquired from food.
People use L-tryptophan for some mental health disorders, to help quit smoking, for athletic performance, and for emotional symptoms in people with premenstrual dysphoric disorder (PMDD), but there is no good scientific evidence to support many of these uses.
