L-Tryptophan 1,000 mg with Bioperine and B vitaminsL-Tryptophan is an essential amino acid and 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. Serotonin is an important neurotransmitter necessary for the regulation of appetite, mood, and melatonin production.*Dietary ConsiderationsWheat FreeDairy/ Milk FreeGluten FreeSoy FreeYeast FreeSugar FreeStarch FreePreservative FreeHydrogenated Oil FreeCorn FreeFree of Artificial Colors/FlavorsSodium Free Serving Size:2 Vegetable Capsule Servings Per Container:30 Amount Per ServingVitamin C (as ascorbyl palmitate)10 mgRiboflavin (as riboflavihn-5 phosphate)10 mgNiacin (as niacinamide)10 mgVitamin B6 (as pyridoxal-5- phosphate)10 mgL-Tryptophan (as TryptoPure)1000 mgBioperine (black pepper extract, fruit)5 mg Other Ingredients:Cellulose, silica Suggested Usage:As a dietary supplement, adults take 2 capsules daily or as directed by your healthcare professionalWarning:If you are taking medications for neurological conditions including Selective Serotonin Reuptake Inhibitors (SSRIs) or Monoamine Oxidase Inhibitors (MAOI), or are pregnant or nursing, do not use this productThis product contains NO yeast, wheat, gluten, soy protein, milk/dairy, corn, sodium, sugar, starch, artificial coloring, preservatives, or flavoringKeep out of reach of childrenFor optimal storage conditions, store in a cool, dry place (59-77F/15-25C)(35-65% relative humidity)Tamper resistant package, do not use if outer seal is missing.
