Most people think of melatonin as a sleep aid, but it’s also been shown to improve quality of life by improving mood, reducing anxiety and stress levels, and improving sleep habits. There is some limited evidence that taking melatonin before bed can help you fall asleep more quickly and stay asleep longer, but the jury is still out on how long before bed is the ideal time to take it. Some experts say you should take it as early as 30 minutes before bed, while others suggest waiting until closer to 10pm. The bottom line: experiment a little and see what works best for you!
