Effects of Ashwagandha ( Withania somnifera) standardized root extract on physical endurance and VO 2max in healthy adults performing resistance training: An eight-week, prospective, randomized, double-blind, placebo-controlled study

Randomized Controlled Trial

Human

2023

This study used exactly the same ashwagandha dose (600mg/day), same training duration (8 weeks), same population (healthy adults 18-45), and measured the same outcome (bench press strength) as the claim describes. The results showed significant improvements in bench press strength for both males and females, matching the p-values in the claim.
