Melatonin – Natural Support for Sleep Disorders

Melatonin is a natural hormone produced in the pineal gland at the base of the brain. It plays a key role in the regulation of sleep and is believed to be important in maintaining the body’s normal circadian rhythm. Melatonin has been used for two primary reasons: sleep-related problems and jet lag.

Studies Show Effectiveness as a Sleep Aid

A 1995 Gallup Poll revealed that approximately one-half of all Americans suffer occasional or chronic sleep problems. Melatonin became popular as a sleep aid in the 1990’s. This usage has been supported repeatedly by scientific studies. As a sleep aid it appears most effective in those suffering mild and occasional insomnia or trouble falling asleep.

The second most common usage for melatonin is as a counter agent for jet lag. In one study, passengers taking melatonin before, during or after an eastward flight found relief for jet lag although the effect was less pronounced for those flying westward. A review of nine clinical trials in 2002 revealed that taking 5 mg of melatonin between 10 p.m. and midnight at the destination helped travelers fall asleep faster and sleep better.

One lesser-known effect of Melatonin is its role in controlling the timing and release of female reproductive hormones. Melatonin helps determine when menstruation begins, the frequency and duration of menstrual cycles and when menstruation ends (menopause).
