5-HTP Synergy™ is a synergistic formula of 5-hydroxytryptophan (50 mg) and vitamin B6 (10 mg) per serving for supporting overall neurotransmitter metabolism by providing precursors of serotonin. 5-HTP readily enters the blood–brain barrier; however, conversion into serotonin requires the cofactor vitamin B6, which is included in this formula. 5-HTP Synergy™ may be used during the day to support a healthy mood and normal appetite, or it may be used at bedtime to support sleep.*
