About Defined Sleep

Defined Sleep was developed by Paul Muchowski, Ph.D., a neuroscientist and former UCSF professor. It was tested in an FDA-registered, double-blind, placebo-controlled, randomized crossover trial, with sleep stages measured every night by a validated wearable (actigraphy). Participants with the lowest starting levels got up to 2x more deep and REM sleep.

KNOCK55 applies to one full bottle, one-time purchase, once per customer. It cannot be combined with other offers and does not apply to subscriptions, which are already $55 per delivery.

These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. “Up to 2x” deep and REM sleep describes the low-baseline responder subgroup in our clinical trial, measured nightly with a validated wearable (actigraphy).
