Ashwagandha extract improves sleep quality in adults with stress-related sleep complaints

Clinical trials with standardized ashwagandha extracts have shown reductions in stress-related biomarkers along with improvements in sleep quality. The review highlights that ashwagandha's effects on sleep are mediated through modulation of the HPA axis and GABAergic signaling.

Frequently Asked Questions

What is the primary mechanism by which ashwagandha improves sleep?โ–ผ

Ashwagandha modulates the HPA axis and affects GABAergic signaling, which collectively contribute to its anxiolytic and sleep-regulating actions.

Are there any known side effects of ashwagandha for sleep?โ–ผ

The abstract does not report specific side effects, but it notes methodological shortcomings in the reviewed studies, so safety data may be limited.

How long does it take for ashwagandha to improve sleep?โ–ผ

The abstract does not specify a time frame; clinical trials varied in duration, but improvements in sleep quality were observed alongside reductions in stress biomarkers.

Is ashwagandha effective for people without stress?โ–ผ

The reviewed evidence focuses on stress-related sleep improvements; efficacy in non-stressed populations is not addressed in this abstract.
