L-Tryptophan 1,000 mg with Bioperine® and B vitamins

L-Tryptophan is a key amino acid and a foundation for serotonin production. Its transference through the blood-brain barrier is the initial step to creating L-5-Hydroxytryptophan (5-HTP), and then serotonin. This powerful neurotransmitter is vital for maintaining appetite, mood levels, and the production of melatonin!*
