Withania somnifera preparations may influence sleep-related outcomes in humans
The review summarizes evidence from preclinical and human studies suggesting that Withania somnifera (Ashwagandha) preparations may affect stress-related and sleep-related outcomes. However, heterogeneity in extract composition and study design limits firm conclusions, and the overall strength of evidence varies across indications and products.

This conclusion is most relevant to: Humans (general, including those with stress-related complaints) and preclinical models.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Nutraceutical Applications of Withania somnifera: The Scientific Knowledge for Rational Modern Use of the "Ayurvedic Adaptogen". (Foods (Basel, Switzerland), 2026) —
How It Works
The proposed biological pathway:
- ▸Modulation of stress response pathways (e.g., HPA axis)
- ▸Reduction of cortisol levels
- ▸Neuroprotective effects via antioxidant and anti-inflammatory pathways
- ▸Result: Improved sleep quality and reduced sleep disturbances
Who Might Benefit
Evidence fit by population:
- ▸Humans (general, including those with stress-related complaints) and preclinical models
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Heterogeneity in extract composition and study design across reviewed studies
- ▸Overall strength of evidence varies across indications and products, limiting generalizability
Frequently Asked Questions
What is Withania somnifera?▼
Withania somnifera, commonly known as Ashwagandha, is an adaptogenic herb used in Ayurvedic medicine, often included in nutraceuticals and dietary supplements for stress and sleep support.
Does Ashwagandha improve sleep?▼
Some evidence from human studies suggests Ashwagandha preparations may improve sleep-related outcomes, but results vary due to differences in extract composition and study quality.
What is the recommended dose of Ashwagandha for sleep?▼
The review does not specify a recommended dose due to heterogeneity in studies; standardized preparations are needed for clearer dosing guidelines.
Is Ashwagandha safe for long-term use?▼
The review notes that long-term safety data are limited, and further well-designed trials are needed to assess safety and efficacy.
