Withania somnifera preparations may influence stress-related and sleep-related outcomes
This narrative review of literature from 2015 to 2026 suggests that Withania somnifera (Ashwagandha) preparations may affect stress and sleep outcomes, based on preclinical and human studies. However, heterogeneity in extract composition and study design limits firm conclusions, and the overall strength of evidence varies across indications and products.

Frequently Asked Questions
What is Withania somnifera?▼
Withania somnifera, commonly known as Ashwagandha, is an herb used in Ayurvedic medicine and is included in nutraceuticals and dietary supplements.
Does Ashwagandha improve sleep?▼
The review suggests that Ashwagandha preparations may influence sleep-related outcomes, but evidence is limited by study heterogeneity and varying product compositions.
What are the main limitations of the research on Ashwagandha for sleep?▼
Key limitations include differences in extract composition across studies, inconsistent study designs, and varying strength of evidence for different indications.
Is Ashwagandha safe for long-term use?▼
The abstract notes that further well-designed trials are needed to clarify long-term safety, so current evidence is insufficient for definitive conclusions.
