Coenzyme Q10 Ubiquinol and Selenium: what the published research says

PubMed indexes 3 records that name Coenzyme Q10 Ubiquinol and Selenium 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 Ubiquinol and Selenium. 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

3 studies naming Coenzyme Q10 Ubiquinol and Selenium.

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

Sex-Dependent Protective Effect of Combined Application of Solubilized Ubiquinol and Selenium on Monocrotaline-Induced Pulmonary Hypertension in Wistar Rats.

Antioxidants (Basel, Switzerland) · 2022 · PMID 35326199

“Ubiquinol + selenium administration resulted in a less severe increase in the right ventricle systolic pressure in male rats but not in females 3 weeks after the start of the experiment. This sex-dependent effect was not observed in the influence of ubiquinol alone.”

Kuropatkina et al. · From the abstract

Names both Coenzyme Q10 Ubiquinol and Selenium in its title.

The regular supplementation with an antioxidant mixture decreases oxidative stress in healthy humans. Gender effect.

Clinica chimica acta; international journal of clinical chemistry · 2004 · PMID 15469861

Clinical Trial

“The observed modifications in variables associated with oxidative stress are indicative of an effective antioxidant action of the used mixture of lipid soluble compounds, and gender differences suggest that men should optimize their antioxidants defenses earlier in life than women.”

Actis-Goretta et al. · Authors' conclusion

Names Coenzyme Q10 Ubiquinol and Selenium 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, Selenium, 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.
