Ashwagandha for Mood Stabilization
Ashwagandha has some of the strongest herbal evidence for mood stabilization, with multiple meta-analyses showing clinically meaningful reductions in anxiety and perceived stress.
Overview
Verdict
Multiple randomised trials show reduced perceived stress and cortisol with standardised root extract; sample sizes are small and long-term data are absent.
How It Works
Proposed pathways
Dosing & Protocol
Doses used in trials
| Preparation | Dose | Schedule | Notes |
|---|---|---|---|
| KSM-66 root extract | 300 mg twice daily | With food, morning and evening | The most commonly studied regimen for stress and anxiety |
| Sensoril root and leaf extract | 125-250 mg daily | Usually once daily | Higher withanolide concentration; lower milligram dose |
| General range | 250-600 mg daily | Divided or single dose | Standardised to 1.5-5 percent withanolides |
| Trial duration | 6-8 weeks | Continuous | Effects build over weeks; benefit beyond 3 months is unstudied |
Doses refer to standardised extracts, not raw root powder, which is far less concentrated.
Give it six weeks, then reassess
Most trials measured their primary outcome at 60 days. If perceived stress and sleep have not shifted by then, further dose escalation is unlikely to help.

Interactions & Conflicts
Clinically relevant interactions
| Interacts with | Severity | Mechanism | Action |
|---|---|---|---|
| Thyroid hormone (levothyroxine) | high | Ashwagandha raises T3 and T4 and can cause thyrotoxicosis on top of replacement | Avoid or monitor thyroid function closely |
| Immunosuppressants | high | Immunostimulant activity may oppose the drug | Avoid in transplant recipients and active autoimmune treatment |
| Sedatives, benzodiazepines, alcohol | moderate | Additive central nervous system depression | Expect increased drowsiness; do not combine before driving |
| Antihypertensives and diabetes medication | moderate | May add to blood pressure and glucose lowering | Monitor readings when starting or stopping |
| Hepatotoxic drugs or alcohol | moderate | Compounding risk of drug-induced liver injury | Avoid the combination; do not use with existing liver disease |
| Pregnancy and breastfeeding | high | Traditional abortifacient use; no safety data in lactation | Contraindicated |
