Table of contents:

Tryptan (generically known as Tryptophan) is an essential amino acid used to treat bipolar affective disorder. It works by affecting the levels of certain chemicals in the brain called neurotransmitters.

Tryptophan can be used for insomnia, sleep apnea, anxiety, facial pain, a severe form of premenstrual syndrome called premenstrual dysphoric disorder (PMDD), smoking cessation, grinding teeth during sleep (bruxism), attention deficit-hyperactivity disorder (ADHD), Tourette's syndrome, and to improve athletic performance.

Low levels of tryptophan can lead to decreased serotonin, which may cause problems like insomnia, depression, and anxiety. Tryptophan is an antidepressant indicated to produce melatonin and serotonin, Melatonin helps regulate the sleep-wake cycle, and serotonin is thought to help regulate appetite, sleep, mood, and pain.
