Coenzyme Q10 and Fenofibrate: what the published research says

PubMed indexes 5 records that name Coenzyme Q10 and Fenofibrate together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Coenzyme Q10 and Fenofibrate. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

5 studies naming Coenzyme Q10 and Fenofibrate.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Hemodynamic effects of fenofibrate and coenzyme Q10 in type 2 diabetic subjects with left ventricular diastolic dysfunction.

Diabetes care · 2008 · PMID 18487480

Randomized Controlled Trial

“In type 2 diabetic subjects with LVDD, neither fenofibrate nor CoQ, alone or in combination, improved diastolic function significantly. However, fenofibrate and CoQ independently and interactively lowered 24-h blood pressure, and fenofibrate alone reduced 24-h HR.”

Chew et al. · Authors' conclusion

Names both Coenzyme Q10 and Fenofibrate in its title.

Effects of fenofibrate therapy on plasma ubiquinol-10 and ubiquinone-10 levels in Japanese patients with hyperlipidemia and type 2 diabetes mellitus.

Pharmacotherapy · 2006 · PMID 16553501

Clinical Trial

“Our findings suggest that fenofibrate may help produce energy or prevent oxidation by increasing plasma ubiquinol-10 concentration; this effect may protect against the development and progression of atherosclerosis. In addition, treatment with fenofibrate demonstrated a favorable effect on serum lipid parameters.”

Asano et al. · Authors' conclusion

Names both Coenzyme Q10 and Fenofibrate in its title.

Combined effect of coenzyme Q10 and fenofibrate on forearm microcirculatory function in type 2 diabetes.

Atherosclerosis · 2003 · PMID 12732401

Clinical TrialComparative StudyRandomized Controlled Trial

“In conclusion, in this factorial trial we found that only the combination of fenofibrate and CoQ markedly improved endothelial and non-endothelial forearm vasodilator function in dyslipidemic type 2 diabetic patients. The favourable vascular effect of this therapeutic combination could be due to increase in the bioactivity of and/or responses to endothelium-derived relaxing factors, including nitric oxide, and this may entail synergistic stimulation of peroxisome…”

Playford et al. · From the abstract

Names both Coenzyme Q10 and Fenofibrate in its title.

Effect of a long-term treatment with lovastatin or fenofibrate on hepatic and cardiac ubiquinone levels in cardiomyopathic hamster.

Biochimica et biophysica acta · 1993 · PMID 8334156

Comparative StudyAnimal study

“These results suggest that 3-hydroxymethylglutaryl-coenzyme A reductase inhibition (HMG-CoARI) associated with lovastatin treatment in cardiomyopathic hamsters is more marked in the liver than in the heart, while ubiquinone concentrations are more decreased in cardiac than in hepatic tissues. Our data also showed that fenofibrate had no effect on ubiquinone levels.”

Bélichard et al. · From the abstract

Names both Coenzyme Q10 and Fenofibrate in its title.

Can coenzyme Q10 alleviate the toxic effect of fenofibrate on skeletal muscle?

Histochemistry and cell biology · 2023 · PMID 37270716

Human subjects

“Treatment with CoQ10 could markedly ameliorate these FEN-induced structural changes and mostly regain the normal architecture of muscle fibers due to its antifibrotic and antiapoptotic effects. In conclusion, treatment with CoQ10 improved muscular structure by suppressing oxidative stress, attenuating inflammation, and inhibiting apoptosis.”

El-Bassouny et al. · From the abstract

Names both Coenzyme Q10 and Fenofibrate in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Coenzyme Q10, Fenofibrate, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
