Feel great in the morning, after getting quickly to sleep and staying asleep for hours
I’ve tried many natural approaches to sleeping, and this has been consistently the best over an extended period (weeks) of assessment. This is my new go-to night-time supplement, best taken 30 mins before bed. retiring for the night. I’m a big fan of glycine sticks (3mg) to get to sleep quickly, but they don’t keep me under as well as Quantum Sleep capsules do. No knock-out feeling either, so if my 2-yo wakes up, I’m able to get up quickly and get back to sleep, no problem.

I Believe It Truly Works!
Since I started taking Quantum Sleep, my ability to sleep thru the night & also get normal amounts of REM sleep has improved dramatically. Both of those were severe problems but nothing was working & I no longer wanted to compromise my body with OTC or Rx medications. I’d never even heard of this stuff but figured, “Why not?”I’m so glad I did!

I’ve been on it for three weeks and have been sleeping great. My energy level is high all day
This stuff works. I’ve been on it for three weeks and have been sleeping great. My energy level is high all day. Right up to bed time. I have recommended this to two others, and they both experienced great results. A bit of a warning to you, you will be dreaming. And I’ve had some interesting dreams.
