A meta-analysis of five randomized controlled clinical studies (n=449 infertile women) has shown that CoQ10 supplementation increases clinical pregnancy rates compared with placebo treatment or no treatment. The CoQ10 supplementation significantly increases clinical pregnancy rates both overall and in infertility subgroups such as the poor ovarian response subgroup (n=286) and the polycystic ovarian syndrome subgroup (n=163) [Florou 2020].
All study participants were women of reproductive age (mean age 33 years) diagnosed with either poor ovarian response or polycystic ovary syndrome. All were attending an assisted reproductive technology clinic [Florou 2020].
The CoQ10 Association has announced plans to test every Coenzyme Q10Coenzyme Q10 molecules are fat-soluble molecules that are both bsynthesized in the body and ingested in the diet and in supplements. Coenzyme Q10 is synthesized in the body in the same biological pathway as cholesterol. Bio-synthesis of Coenzyme Q10 begins to decline once humans reach their adult years. The reduced production of Coenzyme Q10 cannot be compensated in any practical... Read more about this term product on the market in the US for potency and purity [Schultz 2020, August 13]. If all goes according to plan, the project will be completed by the end of 2020. We look forward to seeing the results of the testing.
Potency of CoQ10 Products
Testing for potency means ensuring that the capsule contains the quantity of Coenzyme Q10 specified on the label.
Earlier this year, in May, 2020, the NOW nutritional supplements company headquartered in Illinois, revealed that its in-house laboratory had tested 10 CoQ10 products purchased on amazon.com.
Coenzyme Q10 pre-treatment of young low-prognosis patients with diminished ovarian reserve or poor ovarian response increased the patients’ ovarian response to stimulation and improved oocyte and embryo quality.
After one completed assisted reproductive technique treatment cycle, the women treated with Coenzyme Q10 had a 32% pregnancy rate and a 29% live birth rate. The women in the control group had a pregnancy rate of 17% and a 16% live birth rate.

Adjunctive treatment of chronic heart failureThe 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...

Statistically significant outcomes may or may not be clinically significant. ... Read more about this term results compared with placebo treatment [Mortensen 2014]:

improved NYHAThe New York Heart Association Functional Classification distinguishes four categories of heart failure according to how much the patients are limited in their physical activity. Category I: No limitation of physical activity. No undue fatigue, palpitation, or shortness of breath. Category II: Slight limitation of physical activity. Comfortable at rest. Fatigue, palpitation, or shortness of breath at ordinary physical activity.... Read more about this term class
Absorption and Bioavailability of the CoQ10 Supplement
CoQ10 supplements are very different from one another. The CoQ10 supplement that gave the beneficial heart health outcomes listed above is a specially formulated CoQ10 preparation, specially formulated with respect to the carrier oils in which the Coenzyme Q10 raw material is dispersed and with respect to the heating and cooling process used in the manufacture of the supplement. It has documented absorption and bioavailability.
Coenzyme Q10 is an essential bio-nutrient that has vitamin-like properties.
It is a vital co-factor in the cellular process of ATPATP (adenosine triphosphate) molecules are the high-energy molecules with easily broken phosphate bonds that release energy to the energy-requiring processes in the cells. Coenzyme Q10 is essential to the process of ATP production.... Read more about this term energy generation.
It is an important lipid-soluble antioxidantAntioxidants 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,...

Coenzyme Q10 is a redox moleculeRedox is the abbreviated term for reduction-oxidation. Coenzyme Q10 molecules are redox molecules. Redox refers to the oxidation state of the molecule. Oxidized Coenzyme Q10 molecules, called ubiquinone (CoQ10), are Coenzyme Q10 molecules that can accept (take on) two electrons and thus become reduced Coenzyme Q10 molecules called ubiquinol. Reduced Coenzyme Q10 molecules, called ubiquinol (CoQH2), are Coenzyme Q10 molecules...

Coenzyme Q10 and Heart Failure
In the Q-Symbio StudyQ-Symbio is the abbreviated name for the two-year multi-center, randomized, double-blind, placebo-controlled study of Coenzyme Q10 supplements as an adjunct treatment of chronic heart failure patients. The name reflects the focus of the study on the SYMptoms, BIomarker status (BNP), and long-term Outcomes (hospitalizations and mortality) of the supplementation. The data from the Q-Symbio study show that long-term supplementation with...

A sub-analysis of the European segment of the international multi-center Q-Symbio Study showed that the CoQ10 intervention also significantly improved the patients’ ejection fractionEjection fraction, sometimes called left ventricular ejection fraction, measures the percentage of blood that the heart pumps out of the left ventricle with each heart contraction. According to the Mayo Clinic guidelines, an ejection fraction above 55% is regarded as normal. An ejection fraction under 50% is regarded as reduced. An ejection fraction below 40% is indicative of heart failure... Read more about this term [Mortensen 2019].
Coenzyme Q10 and High Blood Pressure
Older meta-analyses of the effect of Coenzyme Q10 on hypertensionHypertension is abnormally high blood pressure, usually defined as adult systolic blood pressure above 140 mm Hg or adult diastolic blood pressure above 90 mm Hg. Systolic blood pressure is blood pressure measured during the contracting (pumping) of the left ventricle of the heart. Diastolic blood pressure is blood pressure measured during the relaxation of the left ventricle. A meta-analysis...

A more recent meta-analysis has shown that CoQ10 supplementation is associated with a significant reduction in systolic blood pressure but not in diastolic blood pressure in patients with metabolic syndromeMetabolic syndrome is the medical term for a cluster of conditions such as excess body fat around the waist, high blood sugar, high blood pressure, high cholesterol or triglyceride levels. Metabolic syndrome is associated with increased risk of diabetes, heart disease, and stroke. Individuals with metabolic syndrome are at higher risk of heart disease, diabetes, and stroke and have, therefore,... Read more about this term [Tabrizi 2018].
There are numerous enzyme systems at work in the body to convert ubiquinone, the oxidized form of Coenzyme Q10, to ubiquinol, the reduced form of Coenzyme Q10. Despite marketing claims to the contrary, it is not necessary to take a ubiquinol supplement to get sufficient ubiquinol in the body [Mantle & Dybring 2020]. No worries there.
Fact: Without decent absorption and bio-availability of our CoQ10 supplement, we cannot hope to get good heart health effects.
Fact: There is much variability from one CoQ10 supplement to another. It is important to choose a CoQ10 supplement for which there is documented evidence of absorption and bio-availability as well as published evidence of improvement of heart health signs and symptoms.
Sadly, the claims for the absorption of many CoQ10 supplements have been greatly exaggerated in many cases.
