Defined Sleep bottle and softgels

Keep your sleep on track

The clock moves an hour. Your body takes a while to follow, and darker mornings and evenings make it harder. A steady routine helps.

  1. Shift a little at a time. In the four nights before the change, move your bedtime and wake-up 15 minutes later each night. That's your hour.
  2. Let your phone remember. Set a nightly bedtime reminder and move your alarm as you go.
  3. Keep it steady after. Same bedtime and wake-up every day, weekends included. Get daylight early in the day.
  4. Keep the basics. A cool, dark room. Screens off 30 minutes before bed. No caffeine within 3 hours of bed, no alcohol within 2.
  5. Add more deep and REM sleep. Two Defined Sleep softgels with water an hour before bed.

Sleep, not sedation

Defined Sleep has no sedatives and won't knock you out. It was developed by Paul Muchowski, Ph.D., a neuroscientist and former UCSF professor, and 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.

FALLBACK10 takes $9 off the 5-Night Trial, once per customer, for customers who have not had a trial before. Ends December 10, 2026. It cannot be combined with other offers and does not apply to subscriptions, which are already $55 per delivery. Free or discounted trial purchases are ineligible for the money-back guarantee.

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).
