Melatonin—1 mg [Glandular]. Nature’s Sunshine offers melatonin in two varieties to meet varying body types and personal preferences. Melatonin is a hormone produced by the pineal gland. Melatonin helps the body establish healthy sleep patterns and influences energy and general health. It is also a powerful antioxidant. Melatonin—1 mg offers a smaller amount of melatonin per capsule than NSP’s Melatonin Extra, which offers 3 mg per capsule in an herbal base. A smaller amount of melatonin per capsule allows consumers to customize the amount of melatonin to take to ensure a restful night’s sleep and other benefits. Melatonin—1 mg includes 30 IU of vitamin E as a protective antioxidant for the melatonin.
