Great sleep/relaxation aid

Posted by iHerb Customer on Jun 27, 2017 | Verified Purchase

If you have trouble sleeping, Knock-Out is worth a try. The combination of melatonin, vitamins and herbs works better than many other sleep supplements I've tried. I've had the mid-night waking variety of insomnia since my daughter was born 20 years ago. (Very light sleeper.) I have taken increasing doses of melatonin for at least 10 years. But my sleep problem has worsened with peri-menopause. Knock-Out has cut down my sleep-troubled nights from 25-30 per month to just 2-3. I take it about an hour before bedtime and usually have trouble keeping my eyes open within the hour. It doesn't make me feel "hung over " in the morning like over-the-counter sleep aids. The tablets are smooth and about the size of a typical vitamin capsule. I have no trouble swallowing them with juice or milk. They do smell strongly of Valerian (evidence that there is sufficient Valerian to help) but the odor does not make me stink.

Thanks for your feedback!

Good ingredients, mixed review.

Did not sedate, but in the long term I feel has improved my sleep-wake cycle. Appreciate the good ingredients, but the product does not warrant the title at these lower dosages.

Thanks for your feedback!

Have used them for about 4 nights. So far so good really help me sleep. This is a great discovery for me. As I used to have to take strong prescription only sleeping tablets! I have already told my fellow insomniacs.

Thanks for your feedback!
