Melatonin: Is It Safe?

Ask the Doctors

Q: I have heard that melatonin is good for sleep disorders. Is it safe to take, and is it effective?

A: Melatonin is produced by a part of the brain known as the pineal gland. It appears that its function is to keep the body’s internal events synchronized with the changes between light and dark (night and day) in the environment.
