5-Hydroxytryptophan (5-HTP) is a precursor to serotonin, a brain neurotransmitter associated with the feeling of well-being. The precursor to serotonin, our 5-hydroxytryptophan is extracted naturally from the seed of Griffonia simplicifolia. 5-HTP has been shown to support patients with mild, occasional mood changes; occasional restless sleep; and periodic, mild anxiety.
