5 HTP Supreme from Designs For Health is a synergistic formula of 5-hydroxytryptophan (100 mg) and vitamin B6 (20 mg) 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. 5HTP Supreme may be used during the day to support healthy mood or appetite, or at bedtime to support sleep.
