Can a common supplement tame Drug-Resistant epilepsy?
NCT ID NCT07537283
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether taking coenzyme Q10, a natural supplement, can help reduce seizures in adults with drug-resistant epilepsy. Thirty-nine participants took either coenzyme Q10 or a placebo daily for 12 weeks alongside their usual seizure medications. Researchers tracked seizure frequency and cognitive function to see if the supplement made a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- coenzyme Q10
- What this could lead to
- If it works, this could point toward a safe, natural supplement to help control seizures in people whose epilepsy doesn't respond to standard drugs.
- What could go wrong
- This is a small, completed trial with only 39 participants, so results may not apply to everyone. Coenzyme Q10 is generally safe, but it may not reduce seizures for all patients.
