#Ashwagandha
Evidence-based guide to ashwagandha (Withania somnifera) — stress, sleep, recovery, contraindications and interactions.
Ashwagandha (Withania somnifera) is the most-studied adaptogenic herb in modern supplement science. Roots have been used in Ayurveda for over 3,000 years; today's products use standardised extracts (typically KSM-66 or Sensoril).
Evidence. Small but consistent RCTs suggest ashwagandha may help modulate the stress response (lowering cortisol modestly), support sleep quality, and aid resistance-training recovery. Quality of evidence is moderate — most trials are small, short and industry-funded.
Doses. Studied protocols use 250-600 mg/day of a standardised root extract for 6-12 weeks. Higher doses (>1 g/day) raise the risk of GI side effects and have been associated with rare liver-injury case reports.
Who should avoid. People with thyroid disorders (ashwagandha may elevate T4), autoimmune conditions, hormone-sensitive cancers, and those who are pregnant or nursing. It may also interact with sedatives, immunosuppressants and thyroid medication.
Forms. KSM-66 (standardised to 5% withanolides, water-soluble) is the most-cited form for recovery and sleep. Sensoril (10% withanolides, water-and-alcohol-extracted) is more studied for anxiety and cortisol modulation.
On HealthyHerbology we cover ashwagandha across women's adaptogen and hormonal-support angles, men's testosterone-adjacent and recovery angles, and sleep-supportive supplementation.
