Why Defined Sleep
Up to 2× More Deep and REM Sleep, Clinically Proven
Proven Efficacy
Defined Sleep was shown to increase deep & REM sleep (restorative sleep) in a landmark human clinical trial.
Non-Sedating
Defined Sleep does not make you drowsy. It works by increasing deep & REM sleep. It contains no sedatives that ‘knock you out’.
Safe to Take Every Night
Defined Sleep is non-intoxicating, has no fall risk, and is non-addictive/not habit forming.
Optimal for Shift Workers
Study participants who slept during the day (e.g. shift-workers), were highly responsive to the treatment with Defined Sleep.
No Side-Effects
Defined Sleep displayed an excellent safety profile in our clinical trial, had no effect on heart rate or heart rate variability, and no adverse events were observed by study participants.
Drug-Test Safe
Our plant-based formula contains no THC or other ingredients screened for in workplace drug tests.

“Insomnia is a common symptom associated with many psychiatric conditions, including anxiety. I recommend Defined Sleep to my psychiatry patients because it is a safe and effective alternative to stronger sleep medicines.”
