Review (1/5): Terrible and waste of money
Absolutely no effect and poorly designed container. Label color/print color difficult to read unless held under extremely bright light, which you do NOT want to do while getting ready to sleep. Cap does not stay on, so you would never be able to travel with it. Of course, there is no reason to include it in your travel bag as the tiny amount of melatonin in this is useless. I wasted my money on this.
