DEEP + REM SLEEP SUPPORT

The Rest Difference
No melatonin. No sedatives. Just better sleep quality.
No melatonin. No sedatives. Just better sleep quality.
Most sleep supplements follow a common formula - a combination of melatonin and/or sedatives (i.e. valerian). Unfortunately, both have been shown to negatively impact Deep and REM sleep quality (explaining why you’ll often wake up groggy and unrefreshed).
Rest takes a different approach by focusing on minerals and amino acids that work with our biology to support the brain’s natural sleep rhythms, helping you transition into Deep and REM sleep stages faster and stay in them longer.

The Benefits
Get the kind of sleep you’ve been dreaming about
Get the kind of sleep you’ve been dreaming about
The quality of your sleep impacts every part of your life. Mental, emotional and physiological wellbeing are all inextricably tied to how much time you spend in Deep and REM sleep each night.
Rest uses targeted forms of magnesium, amino acids and botanical extracts - all shown to relax the nervous system and increase time spent in restorative Deep and REM sleep phases.

A great sleep aid product! A great sleep aid product! Sleep came quickly and easily, and no restless moments waiting and staring into darkness. I consistently slept through the night and awoke feeling well rested; no morning yawns. The powder dissolves easily and completely in small amount of water which is beneficial since drinking before bedtime. Noticeably provided a deeper relaxing sleep

I honestly wasn’t expecting much but I have to say this definitely gets you into a deeper more satisfying sleep. I like it so much I’m actually packing it in my suitcase to go on a work meeting. Hopefully it will help me get a good nights sleep while I’m out in Salt Lake City!
