For restful sleep and increased mood stability, this unique formula regulates innate circadian rhythm balance and helps to maintain control of homeostasis. A synergistic mix of Melatonin (250 mcg per cap), 5-HTP (50 mg), St. John's Wort (120 mg) and vitamin B6 (15 mg) works to help the body synthesize indolamines -- serotonin & melatonin -- for deep, restful sleep. By regulating circadian sleep rhythms, you'll wake feeling renewed, refreshed, and energetic. Recommended intake is one to three capsules a day, at bedtime or late in the afternoon on an empty stomach.
