Is melatonin any use for insomnia?
We asked Professor Russell Foster:
Melatonin is a hormone produce in the pineal gland. Itís highly regulated by light. Itís produced at night. Thereís two bits of evidence to suggest it might be useful. 1, if you take melatonin about 70% of people will fall asleep; 2, it may help you shift your body clock. The evidence emerging is that yes, it may help you sleep.
Chris - Is it harmful?
Russell - We donít have any evidence that itís harmful. I certainly wouldnít recommend using it without discussing with your GP first.
