Two independent meta-analyses of the available research literature have shown that Coenzyme Q10 supplementation is associated with healthy levels of bio-markers for chronic systemic inflammation [Zhai 2017; Fan 2017].
- Chronic inflammation – a persistent low-grade inflammation – can have deleterious effects throughout the body. Over time, it can result in tissue damage.
- Chronic inflammation is something different from acute inflammation, which is the immune system’s short-term response to an injury or an infection.
- Chronic low-grade inflammation has been linked to increased risk of heart disease, stroke, diabetes, and metabolic disorders [Zhai 2017].
- The extent of chronic low-grade inflammation can be measured by testing for the blood levels of known bio-markers for inflammation [Zhai 2017].
Coenzyme Q10 Effect on Tumor Necrosis Factor-Alpha
Zhai et al analyzed nine randomized controlled trials enrolling 428 study participants. The results of their analysis showed that CoQ10 supplementation significantly improved the serum concentration of Coenzyme Q10 by 1.17 micrograms per milliliter on average compared to placebo treatment [Zhai].
Note: The cardiologist Dr. Peter H. Langsjoen has stated that it is important to raise plasma/serum CoQ10 levels above 2.5 micrograms per milliliter to have a therapeutic effect on the cardiovascular system [Langsjoen 2014].
In the Zhai meta-analysis, the increased serum CoQ10 concentrations were associated with a significant decrease in the inflammation bio-marker tumor necrosis factor-alpha (TNF-α) by 0.45 picograms per milliliter.
Note: Increased blood concentrations of TNF-a are common in both acute and chronic inflammation. Reducing TNF-a levels is a potential therapeutic goal for reducing the risk of atherosclerosis and diabetes and metabolic disorders [Zhai 2017].
Coenzyme Q10 and Bio-Markers of Chronic Inflammation
Fan et al examined the data from 17 randomized controlled trials enrolling 811 patients (412 assigned to the CoQ10 treatment group and 399 assigned to the placebo control group).
The researchers found that the CoQ10 supplementation was associated with a significant reduction of the blood levels of C-Reactive Protein (C-RP) and TNF-a compared to the placebo treatment. They were able to show that the reduction in C-RP levels was independent of the baseline CR-P levels, the treatment duration, the treatment dosage, and patient characteristics [Fan 2017].
Note: C-Reactive Protein is a protein produced in the liver. During times of elevated inflammation in the body, the concentrations of C-RP increase in the blood, making it a good bio-marker for detecting chronic inflammation.
Note: The immune system produces interleukin 6 (IL-6) at the site of the inflammation. At healthy levels, IL-6 acts as a defense mechanism; however, at elevated levels, it can have a pro-inflammatory effect [Gabay 2006].
Decrease in Inflammatory Bio-Markers with Selenium and Coenzyme Q10 Combination
Neither the Zhai study nor the Fan study included data from the KiSel-10 study conducted by Professor Urban Alehagen and a team of university researchers. Zhai and Fan concentrated on studies using a single supplement: Coenzyme Q10.
The four-year KiSel-10 study was a study of the effect of combined daily supplementation (200 milligrams of Coenzyme Q10 and 200 micrograms of high-selenium yeast) on senior citizens. The KiSel-10 study results showed the following statistically significant outcomes:
- reduced risk of death from heart disease
- improved heart function as seen on echocardiograms
- improved health-related quality of life
In follow-up analyses, Professor Alehagen and his team confirmed that the combined supplementation regimen was significantly associated with reductions in the levels of a number of inflammatory bio-marker concentrations [Alehagen 2015; Alehagen 2019].
Summing up: CoQ10 Supplementation and Chronic Inflammation
- Our bodies produce less and less Coenzyme Q10 as we get older [Kalen 1989].
- Coenzyme Q10 has a number of clinically important functions in the body [Littarru 2010].
- Coenzyme Q10 is safe, well-tolerated, effective, and affordable.
Important to Keep in Mind When Buying a Coenzyme Q10 Supplement
- Not all CoQ10 supplements are absorbed equally well. To get the anti-inflammatory effect and the beneficial heart health effects, it is important to buy a CoQ10 supplement that is well-documented.
- The formulation of the CoQ10 supplement is more important than the form of the CoQ10 supplement [Lopez-Lluch 2019]. The ubiquinone form of Coenzyme Q10 is the more stable, better documented (in terms of absorption and health effects), and more affordable CoQ10 supplement.
- Adequate intakes of Coenzyme Q10 are important for energy, for immune defense, and healthy ageing.
