L-Tryptophan, supplies 1000 mg of pure L-Tryptophan plus other synergistic cofactors in two vegetarian capsules.

FUNCTIONS: 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.

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.ニ Other studies indicate L-tryptophan may support women's emotional well being before menstruation.ニ

Additional research indicates L-tryptophan may be helpful in supporting healthy relaxation and occasional food cravings.ニ

L-Tryptophan is a natural relaxant, helps alleviate insomnia by inducing normal sleep; reduces anxiety and depression and stabilizes mood; helps in the treatment of migraine headaches helps the immune system function properly; aids in weight control by reducing appetite; enhances the release of growth hormones; helps control hyperactivity in children.
