Key Benefits of Ashwagandha for Anxiety
Scientific Evidence & Research
A landmark 2012 double-blind, placebo-controlled study in the Indian Journal of Psychological Medicine (Chandrasekhar et al., PMID: 23439798) found that 300 mg of ashwagandha root extract twice daily reduced perceived stress scores by 44% and serum cortisol by 27.9% compared to placebo over 60 days. A 2019 RCT in Cureus (Salve et al., PMID: 32021735) confirmed that 240 mg/day significantly reduced anxiety, depression, and cortisol after 60 days. A 2021 systematic review of seven RCTs in Current Neuropharmacology (Speers et al., PMID: 33820868) concluded ashwagandha consistently reduces stress and anxiety across diverse populations.
