How effective is Circadin for jet lag treatment?
Currently within the UK, Circadin (melatonin) is not licensed for the treatment of jet lag. However, clinical evidence shows that melatonin can help with the symptoms of jet lag and it is therefore widely used. Melatonin is a hormone that is produced by a small gland under your brain. It's released in the evening and tells your brain it's time to sleep - this is part of your body clock.
There have been a number of studies to see if taking melatonin supplements can prevent jet lag, but results have been mixed. Available evidence points to a greater benefit the larger the time difference between the two countries visited.
