Natural Factors Melatonin 3mg 90tabs
Health Canada #:
Taking a melatonin supplement restores melatonin levels and improves sleep in at least two ways. First, melatonin produces a sedative effect by inhibiting the activity of the brain’s reticular activating system, which controls the wakeful state. Second, it temporarily resets the sleep phase of the biological clock, entraining it to a desired sleep time.
