Coenzyme Q10 and Gemfibrozil: what the published research says

PubMed indexes 2 records that name Coenzyme Q10 and Gemfibrozil 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.

Read this first

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 Gemfibrozil. 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

2 studies naming Coenzyme Q10 and Gemfibrozil.

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

Gemfibrozil-induced decrease in serum ubiquinone and alpha- and gamma-tocopherol levels in men with combined hyperlipidaemia.

European journal of clinical investigation · 1998 · PMID 9568470

Clinical TrialRandomized Controlled Trial21 participants

“Gemfibrozil treatment of men with combined hyperlipidaemia reduces serum antioxidant levels to the levels seen in healthy normolipidaemic men. The mechanisms and the relevance of this finding remain unclear and need to be addressed in further studies.”

Aberg et al. · Authors' conclusion

Names both Coenzyme Q10 and Gemfibrozil in its title.

Protective effect of coenzyme Q10 in simvastatin and gemfibrozil induced rhabdomyolysis in rats.

Indian journal of experimental biology · 2005 · PMID 16235714

Human subjects

“This suggested involvement of oxidative stress in rhabdomyolysis. Increase in the level of reduced glutathione, superoxide dismutase, catalase and decrease in the level of lipid peroxidation and serum parameters after administration of antioxidant CoQ10 (10 mg/kg.ip) proved the protective effect of CoQ10 in rhabdomyolysis.”

Farswan et al. · From the abstract

Names both Coenzyme Q10 and Gemfibrozil 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, Gemfibrozil, 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.
