Does Ubiquinol Exercise Performance Randomized Trial work?

The current Migaku evidence database contains 2 reusable source documents for Ubiquinol Exercise Performance Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove. - 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). [Zhang Y (2026); evidence level 1] - Additionally, 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); evidence level 1] - Quantitative and qualitative analyses were performed.ResultsThe study screened 14 randomized controlled trials that included a total of 433 subjects. [Zhang Y (2026); evidence level 1] - The reduced form of CoQ 10 , ubiquinol (UQH 2 ), has greater bioavailability than ubiquinone, but the effects of UQH 2 supplementation on mitochondrial respiratory function and exercise capacity are unclear. [Acton JP (2026); evidence level 4] - Compared to pre-supplementation and PLA, UQH 2 supplementation increased plasma [CoQ 10 ] (P 2 : 0.073 ± 0.039 vs. [Acton JP (2026); 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.
