From the manufacturer's website:

L-Tryptophan, provided by Douglas Laboratories®, supplies 1000 mg of pure L-Tryptophan plus other synergistic cofactors in two vegetarian capsules.

Serotonin, an important brain neurotransmitter, is key in the regulation of appetite, mood, and melatonin production. The presence of serotonin in the brain is associated with a balanced emotional state. This is achieved in part by decreasing the activity of certain excitatory hormones, including dopamine and noradrenaline. Serotonin also acts as a satiety signal in the brain, thereby naturally regulating food intake. Additionally, as a precursor of melatonin, serotonin is involved in regulating sleep patterns. Serotonin is unable to cross the blood-brain barrier and is therefore synthesized in the brain. Tryptophan, an essential amino acid, is a precursor for the synthesis of serotonin. Tryptophan crosses the blood-brain barrier and is converted to L-5-Hydroxytryptophan (5-HTP), which in turn is converted into serotonin. Vitamins B2 and B6, niacinamide and Vitamin C are necessary cofactors to ensure the proper synthesis of serotonin. Studies indicate that supplementation with L-tryptophan may support healthy mood and restful sleep.† Other studies indicate L-tryptophan may support women’s emotional well being before menstruation.† Additional research indicates L-tryptophan may be helpful in supporting healthy relaxation and occasional food cravings.
