Check the listing for details. Tryptophan (Stress, Mood, Sleep) 60 caps by Davina. Condition: New. Listed at 19.99 USD. DescriptionL-Tryptophan is soothing and comforting, great for those with anxiety and sleep disturbances. It achieves these calming effects because it acts as a precursor to serotonin and melatonin. First, it gets converted into 5-hydroxytryptophan (5-HTP), then it’s transformed into serotonin, which is then changed into melatonin. Melatonin is a very popular supplement often taken to aid sleep and to help restore natural sleep/wake cycles. Serotonin (one of the main feel-good hormones) can relieve anxiety, help with depression and sleep, and can act as a natural mood stabilizer.Tryptophan may be beneficial for a variety of conditions. Researchers are looking into a possible connection between lower Tryptophan levels and Chronic Fatigue Syndrome and Fibromyalgia. Studies suggest that supplementing with Tryptophan may increase serotonin levels, which may help ease symptoms. Migraine sufferers may also benefit from supplementing with Tryptophan. Tryptophan depletion was found to increase nausea, light sensitivity and pain in migraine sufferers.L-Tryptophan usually starts working within 20-30 minutes after ingestion.Health BenefitsAnxietyMoodHelp Reduce InsomniaEase Migraines & HeadachesMay Aid Chronic Fatigue Syndrome & FibromyalgiaSuggested Use: Take 1 capsule 1-3 times daily for mood and stress.
