Summary

This study tested whether taking a cistanche supplement for 8 weeks, along with a supervised training program, improves anaerobic exercise performance and recovery in young men. 56 men aged 18-25, either elite or amateur athletes, were randomly assigned to receive cistanche extract or a placebo. Researchers measured jump height, cycling power, and recovery markers like blood lactate and muscle damage indicators.

What this could mean

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

Active substance
Cistanche deserticola extract (a dietary supplement)
What this could lead to
If it works, this could point toward a natural supplement that helps athletes improve explosive power and recover faster after intense exercise.
What could go wrong
This is a small, completed trial with only 56 men, so results may not apply to women or other groups. The supplement may show no benefit over training alone.
