Metabolic Maintenance Melatonin 2mg supports healthy blood pressure, promotes restorative sleep, and aids in protecting nerve health. Melatonin is intimately involved in synchronizing the body's hormone secretions, setting the brain's internal clock and generating circadian rhythms. Melatonin is a hormone we produce naturally. Preliminary findings suggest it may help support normal nerve function and healthy blood pressure. Recommended Use: Take 1 capsule at bedtime, or as directed by a healthcare professional.
