The Defined Difference

300 mg CBD + 8 Sleep Enhancing Terpenes

Defined Sleep contains a generous 300 mg of pure CBD per dose. It's the optimal foundation for deep sleep and up to 7x more CBD than other brands.


But our proprietary formula goes beyond just CBD. We've also integrated 8 naturally occuring, plant-based molecules called terpenes. Studies indicate these specific terpenes can amplify CBD's inherent sleep-promoting effects.

Restorative Sleep

Why Restorative Sleep?

It's All About Wellness

Science shows our brains go through a four-stage cycle when we sleep. Restorative sleep refers to the two latter stages – Deep Sleep and REM Sleep. Combined, they play a key role in recharging our physical and mental systems.

When we get enough restorative sleep, major benefits include boosting our immune systems, regenerating cells, increasing memory and, of course, feeling fully rested.  

Shift Work Sleep Disorder

Our groundbreaking clinical sleep trial showed that shift workers had the best response to Defined Sleep’s formula, enjoying longer periods of time in deeper, higher quality sleep.

Why Do Shift Workers Struggle with Sleep?

A condition called shift work sleep disorder, a type of insomnia, was diagnosed in a high percentage of first responders, medical professionals, airline crews, commercial drivers, factory workers and others whose schedules don’t sync with our natural, internal clocks.

Not only does a lack of sleep impact energy and mood, shift workers are at higher risk for a variety of health conditions according to the National Institute for Occupational Safety and Health. 

These include:

  • Cardiovascular disease

  • Gastrointestinal disorders

  • Psychological disorders including anxiety depression and PTSD

  • Type 2 diabetes

  • Cancer

  • Adverse reproductive outcomes

Only a good night’s sleep can combat what’s known as “sleep debt”, a deficit in the Deep and REM sleep phases which are crucial for human well-being.

Clinical Trial Efficacy

Defined Sleep increased restorative sleep in a pioneering, comprehensive human clinical trial. It is the only CBD sleep-aid that can make this claim. Details of our groundbreaking study are available in the Our Science section of our website.

Purity & Potency

Defined Sleep is made from >99.9% pure CBD isolate. It delivers a more consistent sleep experience compared to products made with impure plant extracts. Our formula also contains 300 mg of CBD per dose, optimal for human sleep. 

0.0% THC, Melatonin, & Sugar

Studies show THC actually interferes with restorative sleep, and melatonin's effect on sleep is minimal, at best. We've excluded these ingredients from our formula, well as sugars, gluten, hormones and any other components that may conflict with the sleep process. 

Created by Scientists

Every product claim we make is backed by clinical studies. Defined Sleep was founded by a team of PhD research scientists and medical professionals on the belief that healthcare therapies should live up to their claims.
