Coenzyme Q10 and systemic inflammation: a review

A 2017 meta-analysis of aggregated data from 17 clinical studies shows that Coenzyme Q10 supplementation is associated with reduced levels of bio-markers for systemic inflammation.  Attribution: Austin, V., Crack, P.

Coenzyme Q10 supplementation has a significant lowering-effect on bio-markers of low-grade systemic inflammation. This is the conclusion of a 2017 meta-analysis of 17 randomized controlled studies enrolling 811 study participants [Fan].

Inflammation is an immune system response to harmful stimuli. However, whenever the inflammation persists and becomes a chronic condition, and whenever the circulating levels of cytokines (= substances secreted by immune system cells) are elevated by a factor of two or more, then the inflammation itself can be harmful to the body in the long term.

Coenzyme Q10 and chronic low-grade inflammation

Researcher
Long-term adjunctive treatment of chronic heart failure patients with Coenzyme Q10 supplements is safe and has improved the patients’ symptoms and has reduced the patients’ risk of major adverse cardiovascular events.  Now, researchers have begun to investigate whether adjunctive treatment with Coenzyme Q10 reduces chronic low-grade inflammation.

Chronic, low-grade, systemic inflammation is common in many diseases: cardiovascular disease, metabolic syndrome, non-alcoholic fatty liver disease, obesity, type-2 diabetes [Zhai 2017].  Anti-inflammatory drugs give modest improvement at best and are associated with long-term adverse effects [Esser 2015].  Some researchers have begun to investigate whether Coenzyme Q10 as an adjunctive treatment has anti-inflammatory health benefits.

The results of the KiSel-10 study have shown that daily supplementation with 200 milligrams of Coenzyme Q10 and 200 micrograms of SelenoPrecise® selenium significantly reduced the levels of sP-selectin and hs-CRP, both markers for inflammation, as compared to placebo supplementation.
