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.
