The 21st Century Melatonin 12 mg Quick Release supplement is designed as a max strength sleep aid that helps users fall asleep faster and enjoy more restful sleep, particularly for individuals experiencing occasional sleeplessness. 
Key benefits and features include:
Rapid Absorption: The "quick dissolve" tablets are designed to dissolve in the mouth within 30 seconds, allowing the melatonin to be absorbed swiftly into the system for fast action.
Sleep Cycle Regulation: Melatonin is a natural hormone that helps maintain the body's sleep/wake cycles (circadian rhythm). The supplement supports this process to promote relaxation and sleep.
Relief from Sleeplessness: It is marketed to help with occasional trouble sleeping, which can be caused by temporary stress, aging, travel (jet lag), or changes in seasonal time.
