Coenzyme Q10 supplementation has a The outcome of a clinical trial is thought to have statistical significance, or to be statistically significant, if the outcome is likely not caused by chance at a given statistical significance level, typically at the 0.05 level. Statistically significant outcomes may or may not be clinically significant. ... Read more about this term 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.
In particular, chronic inflammation has been associated with increased risk of several degenerative diseases [Fan]:
- chronic kidney disease
- heart disease
- type-2 diabetes
Coenzyme Q10 supplementation and bio-markers of inflammation
What are the bio-markers of inflammation that were investigated in the studies analyzed by Dr. Fan and his colleagues?
- C-reactive protein (CRP): Elevated levels indicate low-grade inflammation and increased risk of heart disease.
- interleukin-6 (IL-6): Elevated levels indicate infection or tissue damage and increased risk of heart disease and autoimmune diseases.
- tumor necrosis factor-α (TNF-α): Elevated levels indicate infection or injury and risk of increased insulin resistance and heart disease.
Daily dosages of Coenzyme Q10
Coenzyme Q10 supplementation in doses ranging from 150 to 500 milligrams per day was associated with The outcome of a clinical trial is thought to have statistical significance, or to be statistically significant, if the outcome is likely not caused by chance at a given statistical significance level, typically at the 0.05 level. Statistically significant outcomes may or may not be clinically significant.... Read more about this term reductions in the circulating levels of CRP, Il-6, and TNF-α [Fan].
In the aggregated meta-analysis data, there is a trend towards greater lowering of inflammation levels with greater daily dosages of Coenzyme Q10 [Fan].
Treatment duration was not associated with any statistically significant differences in inflammation lowering effect [Fan].
Coenzyme Q10 supplementation and lipoprotein (a) levels
A 2016 meta-analysis of seven randomized controlled trials enrolling a total of 409 study participants has shown that daily Coenzyme Q10 supplementation significantly lowers plasma lipoprotein (a) concentrations [Sahebkar].
Research results have associated elevated blood levels of lipoprotein (a) with an increased risk of developing coronary heart disease or stroke [Sahebkar].
Moreover, lipoprotein (a) has been identified as a carrier of the oxidized phospholipids that serve to up-regulate the inflammatory process.
It is possible that Coenzyme Q10 supplementation reduces the level of systemic inflammation and reduces the risk of heart disease and stroke by reducing plasma lipoprotein (a) concentrations [Fan].
Effect of formulation of Coenzyme Q10 supplement
Dr. Fan and colleagues were not able to do a sub-analysis of the research data by the formulation of the Coenzyme Q10 supplements. It would be interesting to know which Coenzyme Q10 supplement formulations produced the greatest inflammation lowering effects.
In the context of Coenzyme Q10 absorption and clinical efficacy, formulation is undoubtedly mega-important.
If we want to work backwards from clinical study results to absorption to formulation, then we can look at the randomized, A double-blind study is a study in which neither the investigators nor the study participants know which participants are receiving the active treatment and which participants are receiving the control treatment until the study has been completed and the seal on the code has been broken....

- Dr. Svend Aage Mortensen’s 2014 Q-Symbio study: 300 milligrams of Coenzyme Q10 per day, taken as 100 milligrams three times a day, resulted in improved symptoms and survival for The Mayo Clinic defines heart failure, also known as congestive heart failure and/or chronic heart failure, as the failure of the heart muscle to pump blood to the body adequately. In other words, heart failure is not a heart attack, and it is not death from heart disease, which its name might seem to imply. Heart failure is a condition... Read more about this term patients.
- Professor Urban Alehagen’s 2013 KiSel-10 study: 200 milligrams of Coenzyme Q10 in combination with 200 micrograms of high-selenium yeast daily significantly reduced the risk of death from heart disease in healthy elderly citizens in Sweden. Moreover, the combination supplementation significantly reduced the blood levels of C-reactive protein – a known bio-marker for elevated inflammation and for increased risk of heart disease.
- Professor Beatrice Golomb’s 2013 Gulf War Illness study: 100 milligrams of Coenzyme Q10 per day improved the physical function of veterans diagnosed with Gulf War Illness – quite possibly caused by exposure to the pesticides used around the US military camps in Iraq – and alleviated such symptoms as headaches, fatigue after exercise, muscle pain, irritability, and memory problems. Patients taking Coenzyme Q10 supplements showed improvement in 19 of the 20 symptoms studied.
Coenzyme Q10 is an essential bio-nutrient. Supplementation with Coenzyme Q10 is increasingly necessary as we get up in years. Our bodies synthesize less Coenzyme Q10 as we age. We cannot make up the difference in the foods we eat.
Coenzyme Q10 plays several vital roles in human health:
- cellular energy production
- Antioxidants are substances that protect the cells and lipoproteins against the harmful effects of free radicals. They are substances that prevent the oxidation of other molecules and compounds. There are two broad categories of antioxidants: enzymatic and non-enzymatic. Non-enzymatic antioxidants are substances like Coenzyme Q10, vitamin C, vitamin E, glutathione, and various carotenoids. Prominent enzymatic antioxidants include catalase, glutathione peroxidase,... Read more about this term protection of cells, lipids, proteins, and DNA
