Is Coenzyme Q10 Exercise Performance Randomized Trial safe?

Updated May 2026

Quick Answer

Coenzyme Q10 Exercise Performance Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: The results demonstrated that oral coenzyme Q10 elevated blood coenzyme Q10 concentration (standardized mean difference: 2.710, 95% confidence interval: 1.57-3.85, p < 0.00001) and reduced blood malondialdehyde concentration (standardized mean difference: -0.289, 95% confidence interval: -0.541 to -0.038, p = 0.024).

  • 02Additionally, oral coenzyme Q10 was found to reduce blood creatine kinase values (standardized mean difference: -1.532, 95% confidence interval: -2.856 to -0.209, p = 0.023), suggesting a potential protective effect on skeletal muscle. [Zhang Y (2026)]

[Bagheri Navid (2025); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
