5-HTP Plus Formula capsules, provided by Douglas Laboratories, contain 75 mg of natural L-5- hydroxytryptophan (5-HTP) extracted from seeds of the Griffonia plant, together with 7.5 mg of pyridoxal-5-phosphate and 50 mg of a proprietary blend of the neurotransmitters L-tyrosine and Lglutamine. This product has been certified to be free of a contaminant, peak "x", implicated in a past incidence of dietary tryptophan-associated eosinophilia myalgia syndrome (EMS).
One to two capsules per day, between meals or as directed by a physician. Vitamin B6 is necessary for the conversion of 5-HTP to serotonin. Thus, an adequate intake of vitamin B6 is necessary to derive optimal benefits of 5-HTP.
Store in a cool, dry place, away from direct light. Keep out of reach of children.
