Key result
Ashwagandha supplementation significantly enhanced VO2max in healthy adults and athletes (mean difference 3.00; 95% CI 0.18 to 5.82; p=0.04).
Why the study?
To systematically review the scientific literature on the effects of Ashwagandha supplementation on maximum oxygen consumption and provide directions for clinical practice.

May support Ashwagandha use to enhance VO2max in athletes; extends prior trial evidence on ergogenic supplements.
Meta-Analysis (n=162)
Does Ashwagandha supplementation improve VO2max in healthy adults and athletes?
Mean Difference: 3 (95% CI 0.18–5.82)
p-value: p=0.04
Ashwagandha supplementation may provide a modest improvement in VO2max for healthy adults and athletes, though current evidence is limited by a small number of studies and high heterogeneity.
Pérez‐Gómez et al. (2020) conducted a meta-analysis in Healthy adults and athletes (n=162). Ashwagandha (Withania somnifera) vs. Control was evaluated on Maximum oxygen consumption (VO2max) (MD 3.00, 95% CI 0.18 to 5.82, p=0.04). Ashwagandha supplementation significantly enhanced VO2max in healthy adults and athletes (mean difference 3.00; 95% CI 0.18 to 5.82; p=0.04).
