Does taking a melatonin supplement eventually lead to the body not producing it naturally anymore?

Melatonin: Melatonin is produced in the pineal gland. Seratonin - a neurotransmitter is converted to melatonin. Any hormone taken in excess can lead to the bodies reduction of its own production. Taking normal doses should not affect the bodies normal production. Things like stress and lower seratonin production can lead to lower melatonin levels.
