Ashwagandha root extract combined with melatonin improves sleep quality in adults with sleep disturbances.
In an 8-week RCT, 200 adults aged 18-50 with sleep disturbances received ARE (300 mg twice daily), MLT (3 mg/day), their combination, or placebo. The combination group showed the greatest reduction in sleep onset latency (p < 0.0001) and significant improvements in total sleep time, wake after sleep onset, and sleep efficiency (all p < 0.0001).

The Claim
Ashwagandha root extract combined with melatonin improves sleep quality in adults with sleep disturbances.
This conclusion is most relevant to: Men and women aged 18-50 years with sleep disturbances.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Comparative Evaluation of Ashwagandha (Withania somnifera) Root Extract and Melatonin for Improving Sleep Quality in Adults: A Prospective, Randomized, Double-Blind, Placebo-Controlled Study. (Clocks & sleep, 2026) —
How It Works
The proposed biological pathway:
- ▸Ashwagandha root extract modulates stress and anxiety pathways via cortisol reduction
- ▸Melatonin regulates circadian rhythm and promotes sleep onset
- ▸Combination synergistically reduces sleep onset latency and improves sleep continuity
- ▸Result: Enhanced sleep quality with greater improvements in objective and subjective measures
Who Might Benefit
Evidence fit by population:
- ▸Men and women aged 18-50 years with sleep disturbances
Recommended Dose
ARE 600 mg/day (300 mg twice daily) or MLT 3 mg/day, or combination
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Abstract does not report effect sizes or confidence intervals for primary outcomes
- ▸Mild adverse events occurred across all groups, but details on specific events and dropout rates are not provided
- ▸Study duration limited to 8 weeks; long-term efficacy and safety unknown
Frequently Asked Questions
What is the recommended dose of Ashwagandha for sleep improvement?▼
In this study, Ashwagandha root extract was given at 300 mg twice daily (600 mg/day) for 8 weeks, showing moderate benefits alone and greater effects when combined with melatonin.
Is Ashwagandha more effective than melatonin for sleep?▼
Both Ashwagandha and melatonin monotherapy produced moderate and comparable benefits, but the combination therapy showed the most consistent and pronounced improvements in sleep quality.
What sleep parameters were measured in this study?▼
Objective measures included sleep onset latency, total sleep time, wake after sleep onset, and sleep efficiency via actigraphy. Subjective measures included the Pittsburgh Sleep Quality Index and Hamilton Anxiety Scale.
Were there any side effects of Ashwagandha or melatonin?▼
Mild adverse events occurred across all groups, including placebo, with no clinically significant differences between groups, indicating both treatments were well-tolerated.
