A product review from Business Insider looks at Sleep Well’s melatonin sleep aid Hello Bello.

Sleep Well gummies are formulated with four main ingredients: melatonin, chamomile, lemon balm, and passionflower, all of which are considered natural sleep aids. When taken properly, they may help you fall asleep and rest better through the night.

The star ingredient here is melatonin, which is a hormone produced by our bodies that helps sync our internal clocks with the beginning and end of the day. Research has shown that taking melatonin supplements may help promote sleep. Ideally, our bodies will produce enough of it to help us drift off at night and stay asleep, but sometimes sleep disorders, stress, jet lag, you name it, can get in the way of achieving the recommended seven to nine hours of sleep.

While the other three main ingredients (chamomile, lemon balm, and passionflower) aren’t clinically proven to treat insomnia, they’re the same ingredients found in popular nighttime sleep teas. Many doctors recommend them as natural sleep remedies as well.
