My partner has suffered from sleep problems for a long time and we've tried a few different products but this is the one that's helped him most. He's finding it easier to fall asleep and doesn't get up as frequently at night. Am so thankful we found Deep Sleep!

Amazing product Review by
  • star

Can't believe the difference I feel since taking 'Deep Sleep' no longer do I wake up every couple of hours through the night and I seem to go off to sleep easier. No more lying there for hours waiting to full asleep.

It's Good! Review by
  • star

Bought my first bottle end of last month.

When I first try it, with 1 pill, I can feel tiredness about 40mins later. As I continue and keep the intake constant, it doesn't have the same impact as the first time I take it. I started having dreams and still wake up in the night. Previously, waking up in the night is a torturous experience because I will take 2 hours to sleep again. Since I took this, even if I wake up in the middle of the night, the next few seconds, I'm asleep again.

I was diagnosed with Fibromyalgia in 2013, and the pain has been demoralising and depressing, especially when I have difficulty with sleep. After trying this for close to 2 weeks now, my fibromyalgia hardly flare up. Even if I experience pain, it is minor.

Now..I just bought my 2nd bottle.

Very effective. Review by

Works! Review by

My husband was experiencing insomnia as a result of stress. He constantly woke up at about 2 am and couldn't get back to sleep to the point of sobbing with frustration. After a few nights of taking this supplement, he was finally able to achieve a good nights sleep. Long may it continue!
