Summary

This study tested whether taking ashwagandha (KSM-66) daily for 42 days helps athletes recover from training and improve muscle strength. 56 rugby and water polo players took either 600 mg of ashwagandha or a placebo. Researchers measured stress hormones, muscle soreness, and performance tests like grip strength and jumps.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
ashwagandha (KSM-66) root extract
What this could lead to
If it works, this could point toward a natural supplement to help athletes recover faster and improve muscle strength.
What could go wrong
This is a small, completed trial in healthy athletes, so results may not apply to the general public. Supplements can have side effects, and benefits may be modest.
