Steady sleep for the season
Shorter days and darker evenings can throw off a sleep routine. Keep the habits that help: the same bedtime and wake-up every day, daylight early, lights low in the last hour before bed. Defined Sleep is there for the rest: more time in deep and REM sleep, the stages that leave you rested.

Finding your pattern: some people take it every night, others as needed. Take 2 softgels with water about an hour before bed. If you use a wearable, keep comparing your deep and REM sleep.
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.
