Tryptan (Tryptophan) Dosage and Side Effects

L-tryptophan is an herbal supplement used for depression. Chemically it is a natural occurring amino acid obtained from plants and animals. L-tryptophan is an "essential" amino acid because humans cannot make it and must obtain L-tryptophan from food. It is converted in the body to serotonin. People with depression have an imbalance of serotonin and other brain chemicals. Increased serotonin levels in the brain improve symptoms of depression.
