Herbal edge? tiny study tests ironwort for exercise gains
NCT ID NCT07555288
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will test whether taking a sideritis (ironwort) supplement before exercise can improve performance and recovery in healthy adults aged 18 to 40. Researchers will measure things like oxygen use, heart rate, blood lactate, and time to exhaustion. The trial is very small with only 12 participants, so results will be preliminary.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Sideritis Scardica (ironwort) extract
- What this could lead to
- If it works, this could point toward a natural supplement that helps athletes perform better and recover faster.
- What could go wrong
- This is a very small, early-stage trial with only 12 participants, so results may not apply to everyone. The supplement may show no benefit over placebo.
