Introduction
l-tryptophan is an amino acid, a protein building block that can be found in many plant and animal proteins. l-tryptophan is called an “essential” amino acid because the body can’t make it. It must be acquired from food.
L-tryptophan is used for insomnia, sleep apnea , depression , 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.

Usage
1.Treating premenstrual dysphoric disorder (PMDD). Taking 6 grams of L-tryptophan per day seems to decrease mood swings, tension, and irritability in women with PMDD.
2.Smoking cessation (helping people quit smoking). Taking L-tryptophan seems to improve the effectiveness of conventional treatment for smoking cessation.
How does it work?
L-tryptophan is naturally found in animal and plant proteins. L-tryptophan is considered an essential amino acid because our bodies can't make it. It is important for the development and functioning of many organs in the body. After absorbing L-tryptophan from food, our bodies convert it to 5-HTP (5-hyrdoxytryptophan), and then to serotonin. Serotonin is a hormone that transmits signals between nerve cells. It also causes blood vessels to narrow. Changes in the level of serotonin in the brain can alter mood.
