Published in Journal of Functional Morphology and Kinesiology
Methodology
Systematic review with Bayesian meta-analysis of randomised controlled trials assessing ashwagandha supplementation and physical performance variables including maximal oxygen consumption and strength.
Key Findings
Pooled analysis found ashwagandha supplementation improved maximal oxygen consumption and strength outcomes versus placebo in both healthy and athletic populations, though the credible intervals were wide and the underlying trials were small.
Conclusions
Ashwagandha supplementation appears to improve physical performance variables, but larger and better-controlled trials are needed before firm dosing recommendations can be made.
Limitations
Included trials were small, heterogeneous in extract, dose and population, and many were conducted at a small number of centres with industry involvement.
Supplements Studied
Pooled Bayesian analysis found ashwagandha improved maximal oxygen consumption and strength outcomes versus placebo, with wide credible intervals.
Outcomes Measured
Pooled Bayesian analysis found ashwagandha improved maximal oxygen consumption and strength outcomes versus placebo.
