L-Tryptophan 180

The essential amino acid l-tryptophan is a serotonin precursor. Research indicates that l- tryptophan supplementation may support emotional well-being and restful sleep. 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 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. Niacinamide and vitamin B₆ provide enhanced support as important cofactors involved in the metabolism of l-tryptophan.
