topicUbiquinol Exercise Performance Randomized Trial
claimThe 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).

claimAdditionally, 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.
