Melatonin supplements may help improve sleep quality in adults whose melatonin levels naturally decline with age.

Jet lag occurs when your body's internal clock becomes out of sync with the new time zone. Melatonin can counteract jet lag, a temporary sleep disorder.

Melatonin supplements can help offset the effects of low melatonin levels and normalize your body clock. Your body may know it's nighttime so you can relax and fall asleep more easily.

Each bottle contains 120 quick-dissolving capsules, each containing 20 mg of melatonin. Take 1 capsule 30 minutes before bed.
