The Bottom Line: If lack of Melatonin is the only reason you are not able to fall asleep and stay asleep, then I suppose this product may work for you. It did absolutely nothing for me. I have not slept well in the last two years and I have tried Melatonin, Valerian root, and other sleep aids, and Melatonin is by far the one product that has failed the most miserably in helping me fall asleep and stay asleep. I do appreciate the fact that it is a completely natural product (thumbs up there) but the simple fact is that sometimes, natural does not work. This has been the case for me, unfortunately. I suppose it cannot hurt to take this Nature's Bounty Melatonin, but if you have really problems falling asleep, turning off your thoughts before bed time, and most importantly, staying asleep throughout the night, I do not believe this product will help you. I have gone a different route and after trying just about every over the counter sleep aid on the market, I am now using diphenhydramine and that is the only thing that has helped me so far.
