Melo-Matrix™ is a high-quality, fast acting liquid melatonin. The light blueberry flavoured liquid is easy to administer in incremental volumes, making it suitable for many adult sub-populations. Melo-Matrix™ helps increase the total sleep time (aspect of sleep quality) in people suffering from sleep restriction or altered sleep schedule, e.g. shift-work and jet lag. Melo-Matrix™ also helps to reduce the time it takes to fall asleep (sleep onset latency aspect of sleep quality) in people with delayed sleep phase disorder and re-set the body's sleep-wake cycle.
