Clinical research on Ashwagandha (KSM-66 / Shoden)
MODERATE for cortisol reduction; modest/inconsistent for testosterone in men — mostly industry-funded · 240–600 mg/day standardized root extract
- •RCT in chronically stressed adults: 600 mg/day for 60 days sharply lowered Perceived Stress Scale (p<0.0001) and serum cortisol (p=0.0006) vs placebo — the most-cited stress trial. PubMed
- •Industry-funded RCT (Shoden): 240 mg/day for 60 days reduced morning cortisol and Hamilton Anxiety, and raised DHEA-S vs placebo — attributed to HPA-axis modulation. PubMed
- •Industry-funded RCT in resistance-training novices: 600 mg/day for 8 weeks raised testosterone +96 ng/dL vs +18 ng/dL placebo (p=0.004) — effect unproven in trained men. PubMed
- •RCT in subclinical hypothyroidism: 600 mg/day for 8 weeks normalized TSH (p<0.001) and raised free T3 and T4 — the same thyroid-stimulating effect is a risk in hyperthyroid or medicated patients. PubMed
