Source Naturals L-Tryptophan 500 mg capsules
  • The essential amino acid L tryptophan helps support relaxation, restful sleep, and positive mood.
  • It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response and sleep or wake cycles.
  • L tryptophan also supports immune functions because it is the bodys precursor to the kynurenines that regulate immunity.
  • If needed, L tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system.
  • Source Naturals L tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality.
