Exhale PM is a premium, sleep supplement containing 8 carefully-selected nutrients in amounts that research studies show can dramatically improve the body's ability to fall asleep and stay asleep, which can help you wake up feeling rested, energized, and ready to take on the day. Here at Health & Happiness Labs, we believe in only creating products that meet our exceedingly high standards and that we would take ourselves. Which is why Exhale PM does not contain melatonin or heavy sleep medication which may knock you out for the night but can be habit forming or even inhibit restorative sleep.
