Coenzyme Q10 and Longevity

Metaphorically speaking, CoQ10 supplementation is our umbrella protecting against the risk of chronic degenerative diseases. Studies indicate that 100-300 milligrams of daily Coenzyme Q10 supplementation can reduce the risk of cardiovascular disease, type-2 diabetes, kidney disease, and liver disease.

We all want to live longer, with good health and good energy in our senior years.  One factor that enhances our chances of living longer and better is our ability to avoid chronic degenerative diseases such as cardiovascular disease, diabetes, kidney disease, and liver disease.  Coenzyme Q10 supplements can help.

The rationale for using CoQ10 supplements to enhance our chances for a long and healthy life is based on the role of Coenzyme Q10 in the production of cellular energy.  In addition, Coenzyme Q10 has known antioxidant and anti-inflammatory effects [Mantle & Hargreaves].

Therapeutic Value of Coenzyme Q10 Treatment for Chronic Heart Failure Patients

Dr. Anne Louise Mortensen, lead author of the European sub-group analysis of the Q-Symbio Study of CoQ10 adjunctive treatment of chronic heart failure patients, pictured together with Dr. and Mrs. William Judy. Dr. Mortensen suggests that one reason for the enhanced effectiveness of the CoQ10 treatment in the European sub-group might be better compliance on the part of the patients. CoQ10 supplements can work only if they are taken as they should be: daily, with meals containing some fat, and in divided doses.

The therapeutic efficacy of Coenzyme Q10 adjunctive treatment of chronic heart failure patients – 3 times 100 milligrams daily for two years – was demonstrated in the original Q-Symbio Study (n = 420) published in the JACC specialty journal Heart Failure [Mortensen 2014].

Now, an analysis of just the European portion of the Q-Symbio Study participants (n = 231) has shown that the benefits of Coenzyme Q10 supplementation were enhanced in the more rigorously guidelines-treated European patients [Mortensen 2019].

Coenzyme Q10 and the Heart Muscle

Coenzyme Q10 supplementation is associated with improved left ventricular ejection fraction in more than a dozen randomized controlled studies.

What does Coenzyme Q10 do for the heart?  Quite a lot, it turns out.

Coenzyme Q10 supplementation has been shown in clinical trials to have the following effects with benefit for the heart:

  • improves left ventricular ejection fraction
  • improves endothelial function
  • improves NYHA class
  • improves contractility
  • inhibits platelet aggregation
  • compensates for statin medication

Let’s look more closely at these effects of CoQ10 supplementation.

CoQ10 Supplementation Improves Left Ventricular Ejection Fraction

Ejection fraction is the percentage of the blood that the heart muscle is able to pump out with each heart beat [Cleveland Clinic].

  • In the healthy heart, the ejection fraction should be in the range from 55% to 70%.
  • An ejection fraction of 35% to 40% is indicative of mild heart failure.
  • An ejection fraction below 35% indicates moderate to severe heart failure.

A 2013 meta-analysis of 11 heart failure clinical trials showed that CoQ10 supplementation resulted in a pooled mean net increase in the patients’ ejection fraction [Fotino].

Coenzyme Q10 and Metabolic Syndrome

Metabolic syndrome, also known as syndrome X, is the name for a cluster of conditions – high blood pressure, high blood sugar, insulin resistance, increased risk of blood clots, abnormal cholesterol – that are dangerous themselves and can lead to heart disease and type 2 diabetes.  Coenzyme Q10 supplementation can improve the associated mitochondrial dysfunction and reduce oxidative stress.

Coenzyme Q10, the essential bio-nutrient, has properties that are germane to the treatment of several of the risk factors associated with the umbrella term “metabolic syndrome” [Casagrande].

These properties include the following:

  • a bio-energetics role in the cellular production of ATP energy [Casagrande]
  • a role as a fat-soluble antioxidant protecting against oxidative damage by harmful free radicals to cells and lipids [Casagrande]
  • an anti-inflammatory effect [Zhai]
  • a role in the protection and improvement of endothelial function [Gao]

What Factors Reduce Plasma Coenzyme Q10 Levels?

Typically, we expect to find plasma Coenzyme Q10 concentrations ranging from 0.6 to 1.0 micrograms per milliliter in unsupplemented healthy individuals.  With daily supplementation, it is possible to raise the plasma Coenzyme Q10 levels above the 2.5 micrograms per milliliter level needed for a therapeutic effect in heart disease and above the 3.5 micrograms per milliliter level needed for a therapeutic effect in neurodegenerative disease [Langsjoen].

Dr. Richard Passwater’s interviews with Dr. William Judy (pictured here) in the WholeFoods Magazine are fascinating reading about the absorption and clinical effects of Coenzyme Q10.

In the February and March 2019 issues of WholeFoods Magazine, Dr. Richard Passwater has published part 1 and part 2 of his interview with Dr. William Judy. These interviews are must reading [Passwater 2019].

The Main Coenzyme Q10 Points in the Dr. Passwater – Dr. Judy Interviews

Dr. Passwater’s interviews with Dr. Judy focus on current issues in CoQ10 research. These issues are of interest to all of us who want to maintain good heart health.

Coenzyme Q10 Molecules are Redox Molecules With Oxidized and Reduced Forms

Coenzyme Q10 molecules are redox molecules with an oxidized form of Coenzyme Q10 called ubiquinone, an intermediate partially reduced form called ubisemiquinone, and a reduced form called ubiquinol. The ubiquinone and ubiquinol forms are both used in Coenzyme Q10 supplements. Both forms are active and important forms.

Coenzyme Q10: An Insider’s Guide by Dr. William V. Judy

Dr. William V. Judy, the founder and president of the SIBR Research Institute, was one of the first researchers to raise questions about misleading marketing claims for Coenzyme Q10 products. Now he has written a book to share his knowledge of the relevant clinical research into the absorption, bio-availability, efficacy, and safety of CoQ10 supplements.

Coenzyme Q10 is, literally, the substance that powers life.  It is an essential bio-nutrient required for the cellular process of ATP energy production.  It is also an important fat-soluble antioxidant.  Oral CoQ10 supplementation is positively associated with the reduction of blood bio-markers for oxidative stress and inflammation.

Now available from amazon.com is Dr. William Judy’s new book entitled Coenzyme Q10: An Insider’s Guide. 

A simple search for the words Judy and Q10 will find the book on Amazon.

Coenzyme Q10 Supplements for Patients with Type 2 Diabetes

Diabetes is a major health problem world-wide. More than 90% of patients with diabetes have type 2 diabetes in which case the pancreas does not make enough insulin or the insulin that the pancreas makes is not effective. Patients with type 2 diabetes are at higher risk of developing heart disease, hypertension, and stroke. Oxidative stress is a known factor in the development and progression of type 2 diabetes. Coenzyme Q10 is an important fat-soluble antioxidant that can scavenge harmful free radicals and protect the cells from oxidative damage.

Individuals with type 2 diabetes are known to have considerably lower plasma/serum Coenzyme Q10 concentrations than do individuals who do not have diabetes [Zhang].

A 2018 meta-analysis and systematic review of the research literature indicates that Coenzyme Q10 supplementation improves glycemic control and increases HDL-cholesterol in individuals with type 2 diabetes [Zhang].

CoQ10 Supplementation and Glycemic Control

The results of the meta-analysis, drawn from an aggregated 13 clinical trials enrolling 795 patients with type 2 diabetes, show that the CoQ10 supplementation significantly decreased HbA1c (p=0.03) and fasting glucose (p=0.005).

Coenzyme Q10 and Male Infertility

Data from randomized controlled trials show that Coenzyme Q10 supplementation is positively associated with improved sperm density and motility and, to a certain extent, with improved pregnancy rates.

Coenzyme Q10 supplementation results in significant improvement in various sperm parameters: sperm density, sperm motility, and sperm morphology and, quite possibly, in pregnancy rates [Safarinejad].

Actually, we have known about the benefits of Coenzyme Q10 for treating men with significant abnormalities in sperm morphology and motility for 10 – 15 years now.  Let’s have a look at the clinical research results reported in journal articles indexed by Medline.

CoQ10 and Male Infertility Associated with Abnormal Sperm Parameters

Safarinejad, M. R. (2009). Efficacy of Coenzyme Q10 on semen parameters, sperm function and reproductive hormones in infertile men. The Journal Of Urology, 182(1), 237–248.

Researchers enrolled 212 infertile men with various sperm abnormalities. Half of the patients were randomly assigned to receive 300 milligrams of Coenzyme Q10 daily, and half took matching placebos for 26 weeks.  The researchers then continued to follow the patients’ progress for a 30-week treatment-free phase.

Coenzyme Q10 supplementation and coronary artery disease

Elevated total cholesterol levels and/or elevated low-density lipoprotein (LDL) cholesterol levels are associated with increased risk of coronary artery disease, which is the most common form of heart disease. Now, a meta-analysis shows that CoQ10 supplementation significantly improves total cholesterol and HDL-cholesterol in coronary artery disease patients.

Coenzyme Q10 adjuvant treatment of heart failure patients significantly improves the symptoms and survival of chronic heart failure patients [Mortensen; Morisco; Munkholm].

How does it look with Coenzyme Q10 supplementation and coronary artery disease?

Coronary artery disease is caused by hardening and narrowing of the coronary arteries that bring blood to the heart muscle? Coronary artery disease is also known as ischemic heart disease, which is heart disease characterized by reduced flow of blood containing oxygen to the heart muscle.

Coenzyme Q10 adjuvant therapy for chronic heart failure

Dr. Svend Aage Mortensen (right), pictured here with Dr. Karl Folkers, was the lead researcher on the Q-Symbio study of the effects of Coenzyme Q10 adjuvant therapy for chronic heart failure patients. Now, Dr. Anne Louise Mortensen has focused in on the European patients in the international Q-Symbio study.

There are positive outcomes from an analysis of the European sub-group of chronic heart failure patients (n = 231 out of a total of 420 patients) in the international multi-center Q-Symbio study.  Two years of adjuvant treatment with 3 times 100 milligrams of ubiquinone Coenzyme Q10 daily in addition to conventional heart failure treatment reveals [Mortensen 2019]:

  • significantly fewer patients suffering major adverse cardiovascular events (= death due to heart attack or heart failure or hospitalization due to acute heart failure or pulmonary embolism) compared to placebo
  • significantly fewer heart disease deaths and all-cause deaths compared to placebo
  • significantly more improvements of the patients’ NYHA classifications compared to placebo
  • significantly improved ejection fraction compared to placebo

What was the Q-Symbio study of CoQ10 and heart failure?

The Q-Symbio study was an international multi-center randomized, double-blind, placebo-controlled study that demonstrated that daily treatment with 3 times 100 milligrams of a pharmaceutical-grade ubiquinone Coenzyme Q10 preparation for two years in addition to conventional treatment significantly improved the symptoms and survival of chronic heart failure patients [Mortensen 2014].
