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

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.

Now that my GI issues have resolved I can take magnesium again. I tried twice before but it just made things worse. This time I'm getting more deep sleep with the Rest and the dreams, OMG, I love them. I'm going to make sure this comes in every month with my other supplements from you
