Pure Encapsulations L-Tryptophan | Amino Acid Supplement for Relaxation, Serotonin Support, PMS, and Sleep* | 180 Capsules

The essential amino acid l-tryptophan is a serotonin precursor. Research indicates that l-tryptophan supplementation may support restful sleep. In a double-blind, placebo-controlled study, l-tryptophan supported healthy processing and promoted positive outlook in women. In a separate study, it lessened occasional irritability during the menstrual cycle. l-Tryptophan also supports healthy sleep quality, onset and duration. Additional research suggests that tryptophan may promote relaxation and help control occasional cravings. Vitamin B6 provides enhanced support as an important cofactor involved in the metabolism of l-tryptophan. WHO TO USE: As a dietary supplement, take 2 capsules 1–3 times daily, between meals.
