Improve sleep quality

What this outcome means

Sleep quality is how restful and restorative your nights actually feel, from how soundly you stay asleep to how refreshed you wake. On DoseRank it maps to a defined health outcome built from human studies on sleep efficiency, nighttime awakenings, and next-day restfulness ratings – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Restless nightsTossing and turning that leaves sleep feeling shallow and broken.

Light sleepersEasily roused by noise, light, or a restless partner.

Unrefreshed morningsWaking groggy and drained despite spending enough hours in bed.

Stack buildersAlready taking supplements such as Melatonin or Magnesium Glycinate and want the dose right.
