Myxomatous mitral valve disease is the most common heart disease in dogs. It often leads to congestive 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... Read more about this term. The Cavalier King Charles Spaniel is especially at risk of developing mitral valve disease at an early age. From the onset of congestive 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.

Increasingly, people are feeding their dogs CoQ10 supplements. The CoQ10 supplementation is used provide dogs and cats the following health benefits [Gollakner 2020; Puotinen CJ 2019]:

improved cellular energy production
enhanced 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,...

reduced endothelial dysfunctionEndothelial dysfunction may be thought of as the failure of the cells lining the inside of arteries and veins to regulate properly blood vessel relaxation and contraction, blood clotting, immune function, and platelet adhesion. Endothelial dysfunction prevents the blood vessels from dilating sufficiently and can lead to increased risk of atherosclerosis, heart attack, and stroke. Coenzyme Q10 supplementation is associated... Read more about this term

Typically, the CoQ10 supplement is given by mouth as a capsule or as a liquid. It is possible, of course, to squeeze the CoQ10 filling out of a capsule onto the dog food.

First off, a few definitions:

Coenzyme Q10 is an essential bio-nutrient with vitamin-like properties. It is not considered a vitamin because our cells do synthesize Coenzyme Q10. However, once we reach adulthood, our bio-synthesis of Coenzyme Q10 begins to decline with increasing age [Kalén 1989]. Furthermore, statin medications are known to inhibit the bio-synthesis of Coenzyme Q10 [Okuyama 2015]. Supplementation is a must.

Oxidative stress is the result of an imbalance between the body’s production of harmful free radicalsFree radicals are unstable and highly reactive molecules that are produced in the body during normal oxygen metabolism. Free radicals derived from oxygen are known as reactive oxygen species. Free radicals play both helpful and harmful roles in the body. Free radicals steal electrons from other substances in order to become stable. In so doing, the free radicals oxidize those... Read more about this term as a by-product of metabolic processes and the body’s supply of antioxidants to neutralize the free radicals. Oxidative stress, unchecked, results in damage to cell membranesThe cell membranes, sometimes called plasma membranes, are the physical barrier that protects the contents of the cells from everything that is outside the cells. The cell membranes also regulate what can move in and out of the cells. Coenzyme Q10 is present in all cell membranes in the body except in the red blood cells. It helps to prevent...

Data from a two-year observational study indicate that maintaining high levels of Coenzyme Q10 in plasma during the hardest part of the soccer season helps professional players [Sanchez-Cuesta 2020]:

prevent muscle damage (lower creatine kinase levels)
prevent kidney damage (lower uric acid levels)
reduce stress (lower cortisol levels)
achieve higher physical capacity (video analysis of distance run and running speed)

Based on the results of the observational study, the researchers speculated that CoQ10 can be safely used as a supplement for the prevention of accumulated muscle and kidney damage in elite athletes, possibly even for improving recovery time after intense competition [Sanchez-Cuesta 2020].

Coenzyme Q10 in Plasma is Predominantly in the Ubiquinol State

Coenzyme Q10 molecules are redox molecules with an oxidized state (ubiquinone) and a reduced state (ubiquinol). The Coenzyme Q10 in the plasma is predominantly in the reduced CoQ10 state, i.e. in the state that serves as an electron donor, making it the ideal state for antioxidant neutralization of harmful free radicalsFree radicals are unstable and highly reactive molecules that are produced in the body during normal oxygen metabolism. Free radicals derived from oxygen are known as reactive oxygen species. Free radicals play both helpful and harmful roles in the body. Free radicals steal electrons from other substances in order to become stable. In so doing, the free radicals oxidize those... Read more about this term [Judy 2018].

Statistically significant outcomes may or may not be clinically significant. ... Read more about this term effect on clinical pregnancy rates.

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].
