Why can’t I just take melatonin to help me get to sleep?

You can, but if you have frequent occurrences of waking up at 2 or 3 AM or if you often feel tired, stressed, and sluggish during the day, taking a product that not only helps you fall asleep but helps you reach deep sleep is important. Deep sleep is a state of sleep that has restorative and resilient/healing properties and accounts for good-quality, refreshing sleep.
