The essential amino acid l-tryptophan is a serotonin precursor. It promotes serotonin synthesis to support emotional health and restful sleep.
Positive mood: Research indicates that l-tryptophan supplementation may support emotional well-being. In a double blind placebo-controlled study, l-tryptophan supported healthy emotional processing and promoted positive outlook in women. In a separate study, it supported healthy mood and lessened irritability during the menstrual cycle. Niacinamide and vitamin B6 provide enhanced support as important cofactors involved in the metabolism of l-tryptophan.
Restful sleep and relaxation: Research indicates that l-tryptophan supports healthy sleep quality, onset and duration. Additionally, studies suggest that tryptophan may promote relaxation and help control occasional cravings.
Pure Encapsulations recommends 2-6 capsules daily, in divided doses, between meals.
Not to be taken by pregnant or lactating women. l-Tryptophan can cause gastrointestinal (GI) side effects, including heartburn, belching and flatulence, nausea, vomiting or diarrhea. It has also been related to headache, dry mouth, visual blurring, ataxia, drowsiness and anorexia. Consult your physician for more information.
Tryptophan is contra-indicated with serotonergic medications, including SSRI and MAO inhibitor medications. It is also contra-indicated with sedative and antipsychotic medications. Consult your physician for more information.
