Defined Sleep is the first CBD-based sleep solution to be clinically tested for its effects on human Restorative Sleep.

Each capsule contains a generous 150mg of CBD, plus eight additional plant-derived molecules that further enhance CBD’s sleep promoting properties. In short, it’ll give you a deeper sleep than just CBD alone.


We’re focused on Restorative Sleep, not just sedation.

Defined Sleep is designed differently than prescription sleep medications, the majority of which are potent sedatives/hypnotics that actually decrease Restorative Sleep. Instead of ‘knocking you out’, our product promotes a more natural, gradual drowsiness – then increases Restorative Sleep by extending the time you spend in deep and REM sleep stages. The result is a deeper sleep that leaves you feeling refreshed and relaxed when you awake–not groggy and hungover.


You’re unique. So is your dosage.

The optimal dosage of Defined Sleep, like all medications, is dependent on a variety of factors including your height, weight, diet, body chemistry and lifestyle. As a baseline, we recommended taking two soft gels (300 mg total) about an hour before bedtime. If more effect is desired, it’s OK to take an additional capsule or two.

Note: It’s best to refrain from taking caffeine and alcohol at least three hours prior to bedtime as they may interfere with Defined Sleep’s efficacy.
