Coenzyme Q10 Ubiquinol and Simvastatin: what the published research says

PubMed indexes 4 records that name Coenzyme Q10 Ubiquinol and Simvastatin 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 Ubiquinol and Simvastatin. 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

4 studies naming Coenzyme Q10 Ubiquinol and Simvastatin.

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

MicroRNAs as biomarkers of hepatotoxicity in a randomized placebo-controlled study of simvastatin and ubiquinol supplementation.

Experimental biology and medicine (Maywood, N.J.) · 2016 · PMID 26429200

Randomized Controlled Trial

“Ubiquinol supplementation additionally regulated miRNAs that inhibit apoptotic and inflammatory pathways, suggesting potential hepatoprotective effects. Our results suggest that 20 mg/day of simvastatin does not have significant risk of hepatotoxicity and ubiquinol supplementation may, at the miRNA level, provide potential beneficial changes to reduce the effects of coenzyme Q10 deficiency in the liver.”

Pek et al. · From the abstract

Names both Coenzyme Q10 Ubiquinol and Simvastatin in its title.

Ubiquinol rescues simvastatin-suppression of mitochondrial content, function and metabolism: implications for statin-induced rhabdomyolysis.

European journal of pharmacology · 2013 · PMID 23624330

Human subjects

“Treatment with simvastatin significantly reduced mitochondrial content as well as cell viability which were both rescued by simultaneous treatment with ubiquinol. This work demonstrates that the addition of ubiquinol to current statin treatment regimens may protect muscle cells from myopathies.”

Vaughan et al. · From the abstract

Names both Coenzyme Q10 Ubiquinol and Simvastatin in its title.

Effects of simvastatin on liver and plasma levels of cholesterol, dolichol and ubiquinol in hypercholesterolemic rats.

The Italian journal of biochemistry · 1995 · PMID 7797420

Animal study

“Simvastatin, a drug which blocks hydroxymethylglutaryl coenzyme A reductase (HMGCoAR), reduces plasma cholesterol and increases HDL-cholesterol in rats fed a hypercholesterolemic diet. Moreover, simvastatin produces a significant decrease of ubiquinol and dolichol in plasma and in liver.”

Marinari et al. · From the abstract

Names both Coenzyme Q10 Ubiquinol and Simvastatin in its title.

Effects of diet and simvastatin on serum lipids, insulin, and antioxidants in hypercholesterolemic men: a randomized controlled trial.

JAMA · 2002 · PMID 11829698

Clinical TrialRandomized Controlled Trial

“A modified Mediterranean-type diet rich in omega-3 fatty acids efficiently potentiated the cholesterol-lowering effect of simvastatin, counteracted the fasting insulin-elevating effect of simvastatin, and, unlike simvastatin, did not decrease serum levels of beta-carotene and ubiquinol-10.”

Jula et al. · Authors' conclusion

Names Coenzyme Q10 Ubiquinol and Simvastatin together in an interaction, co-administration, or pharmacokinetic context.

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 Ubiquinol, Simvastatin, 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.
