Does Coenzyme Q10 Supplementation Exercise Performance Randomized Trial work?

Updated October 2026

Quick Answer

Coenzyme Q10 Supplementation Exercise Performance Randomized Trial has evidence relevant to strength of evidence and what the studies can or cannot prove, but conclusions should stay close to the cited sources. One representative finding is: NT-proBNP increased post-Ex1 (19.66%, p = 0.001), post-Ex2 (12.09%, p = 0.001) but decreased in 24 h-Ex1 (- 20.28%, p = 0.001), 24 h-Ex2 (-20.83%, p = 0.001) compared to post-Ex1&Ex2, respectively.

Key Takeaways

  • 01NT-proBNP increased post-Ex1 (19.66%, p = 0.001), post-Ex2 (12.09%, p = 0.001) but decreased in 24 h-Ex1 (- 20.28%, p = 0.001), 24 h-Ex2 (-20.83%, p = 0.001) compared to post-Ex1&Ex2, respectively. [Rahimi MR (2025)]
  • 02Time to fatigue (TTF) improved post-supplementation (- 0.5%, p = 0.002), whereas the placebo showed no change (- 0.08%, p = 0.793). [Rahimi MR (2025)]
  • 03Conclusions CoQ10 supplementation significantly reduced post-exercise cardiac stress markers (GDF-15, NT-proBNP, hs-TnT) and improved TTF in athletes. [Rahimi MR (2025)]
  • 04Background Coenzyme Q10 (CoQ10), a vital mitochondrial antioxidant, may enhance cardiovascular recovery and delay fatigue in athletes. [Rahimi MR (2025)]

This answer focuses on strength of evidence and what the studies can or cannot prove. - NT-proBNP increased post-Ex1 (19.66%, p = 0.001), post-Ex2 (12.09%, p = 0.001) but decreased in 24 h-Ex1 (- 20.28%, p = 0.001), 24 h-Ex2 (-20.83%, p = 0.001) compared to post-Ex1&Ex2, respectively.

[Rahimi MR (2025); evidence level 2] - Background Coenzyme Q10 (CoQ10), a vital mitochondrial antioxidant, may enhance cardiovascular recovery and delay fatigue in athletes. [Rahimi MR (2025); evidence level 2] - 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] 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.
