Having trouble fitting sleep into your schedule? Reset your internal clock and re-establish healthy sleep patterns safely and naturally with Triple Strength Melatonin. A hormone secreted by the pineal gland, melatonin helps regulate the circadian rhythm, the "internal clock" that controls the body's sleep/wake cycle. It also acts as an antioxidant, combating the free-radical damage associated with aging. Our high-potency Triple Strength Melatonin capsules deliver 10 mg of pure melatonin.
