Could a berry blunt exercise fatigue? a trial puts black elderberry to the test
NCT ID NCT07777510
First seen Aug 20, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This trial tests whether taking black elderberry extract can reduce blood lactate and oxidative stress after exercise in young men who work out regularly. Participants take either elderberry capsules or a placebo, then complete exercise tests to measure recovery markers. The goal is to see if this natural supplement could support exercise recovery and reduce cellular stress.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- black elderberry (Sambucus nigra L.) extract capsules
- What this could lead to
- If effective, black elderberry could become a natural supplement to help active young men recover faster from exercise by reducing oxidative stress and fatigue markers.
- What could go wrong
- This is a small early-stage trial with only 19 participants, so results may not apply broadly. Supplements can also cause allergic reactions in some people.
