This product provides a unique spray delivery of 5-Hydroxytryptophan (5-HTP) and Tryptophan. Both amino acids are precursors for serotonin production. Tryptophan is the initial carried form of the amino acid into the blood-brain barrier for serotonin production. 5-HTP is the form of Tryptophan that is further metabolized into serotonin synthesis.
