Ashwagandha for Nighttime Waking

Completed · Not applicable · Has a placebo group

Conditions studied: Disturbed Sleep

In brief

The purpose of this research is to evaluate the effect of a sustained-release, lower-dosage (150mg) Ashwagandha supplement to reduce disturbed sleep. 54 participants, after randomization, will take either an Ashwagandha supplement or a placebo daily for 28 days (week 4) and wear an Oura ring. The Oura ring will measure waking after sleep onset (WASO). Questionnaires to evaluate quality of life and sleep will be administered at baseline and week 4.
