Research indicates that l-tryptophan supplementation may support emotional well-being and restful sleep.1 In a double-blind, placebo-controlled study, l-tryptophan supported healthy emotional processing and promoted positive outlook in women.2 In a separate study, it supported healthy mood and lessened occasional irritability during the menstrual cycle.3 l-Tryptophan also supports healthy sleep quality, onset and duration.4 Additional research suggests that tryptophan may promote relaxation and help control occasional cravings.5 Vitamin B~6~ provides enhanced support as an important cofactor involved in the metabolism of l-tryptophan.6\u003c\/p\u003e\n\u003cp\u003eReferences:\u003c\/p\u003e\n\u003cp\u003e1.
