Why it's a smart traveller's pick: Melatonin is a safe, natural and effective solution for coping with long haul flights (it helps you sleep) and therefore jet lag. Taking melatonin to reduce jet lag is probably the safest and best-tested use of the hormone to date. Melatonin is a hormone produced by your brain and serves to trigger the body's sleep response. It helps your body know when it's time to go to sleep and when it's time to wake up.
