Prolonged-release melatonin or synthetic agonists are required for replacement therapy aimed at maintaining sleep throughout the night, as immediate-release formulations are insufficient for sleep maintenance.
If you fall asleep easily but wake up frequently or early, immediate-release melatonin may not be enough. You may benefit from prolonged-release formulations or synthetic agonists designed to sustain melatonin signaling throughout the night.
GoodQualifiesHIGH confidence
For purposes of a replacement therapy based on longer-lasting melatonergic actions, melatonin prolonged release and synthetic agonists have been developed.
Why this rating
The paper states these formulations were developed for this purpose, implying clinical validation.
