  • TryptoPure
  • Suitable for Vegetarians/Vegans

L-Tryptophan is an essential amino acid and hence cannot be synthesized by the body, but must be obtained from food or supplements. Because L-tryptophan is converted to serotonin (5-hydroxytryptamine) and melatonin in the body, it plays an important role in promoting relaxation, restful sleep and positive mood.

L-tryptophan may also help in reducing carbohydrate cravings.

Jarrow Formulas L-Tryptophan TryptoPure is manufactured at a GMP facility via fermentation from vegetable materials.

Suggested Use

Take 1 capsule on an empty stomach 30 minutes before sleep with water or fruit juice or as directed by your qualified healthcare professional.

Other Ingredients

Magnesium stearate (vegetable source), cellulose and silicon dioxide. Capsule consists of hydroxypropylmethylcellulose.

No wheat, no gluten, no soybeans, no dairy, no egg, no fish/shellfish, no peanuts/tree nuts, no corn.
