L-Tryptophan is a large neutral amino acid essential to human metabolism because it is the metabolic precursor of serotonin (a neurotransmitter), melatonin (a neurohormone), and niacin (vitamin B3) which assist in the regulation of sleep, positive mood and immune function. L-Tryptophan is not synthesized by the body and must be obtained from the diet.
Each capsule contains:
L-Tryptophan 220 mg
Non-Medicinal Ingredients: Veg Capsule (hypromellose, water), Cellulose, Stearic Acid, Hydroxypropyl Methylcellulose.
Adult Dosage: Take 1 capsule daily with meals.
Consult a health care practitioner prior to use if you are pregnant or breastfeeding. Tryptophan supplementation should be avoided in depression with reversed diurnal variation. Patients with liver cirrhosis should avoid tryptophan supplementation.
