What Is It?
The essential amino acid l-tryptophan is a serotonin precursor. It promotes serotonin synthesis to support emotional health and restful sleep.*
Uses For l-Tryptophan
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.*
