I want to share important new research on the popular supplement CoQ10 and its role in supporting cellular energy production. Emerging evidence shows that CoQ10 plays a critical role in muscle energy metabolism, including in the heart—the most vital muscle in the body.
A recent study from the Journal of the American College of Cardiology: Heart Failure found that supplementing with CoQ10 can safely and effectively improve heart function. This is not only great news for those who already have heart function issues, but also for those who want to take preventative steps to ensure protection from cardiovascular concerns in the future.
When the heart pumps, it delivers oxygen- and nutrient-rich blood to the body's cells. When the heart lacks the energy needed to pump at full strength, cells struggle to receive adequate blood flow. This reduced pumping ability is fairly common, and many people who experience it don’t realize anything is wrong. Symptoms may include chronic tiredness, swollen legs, rapid heartbeat, shortness of breath, and coughing. Mild cases may feel symptom‑less but still require attention for long‑term health.
Depending on how severely the heart struggles to pump blood, the New York Heart Association ranks cases from class one through four. The study in Journal of the American College of Cardiology: Heart Failure examined individuals with class three or four difficulties—the most severe—and found that those supplementing with CoQ10 had a significantly lower risk of heart complications than those taking a placebo. Despite beginning the study with major heart function issues, participants taking CoQ10 also saw a significant reduction in cardiovascular mortality risk.
The researchers note that treating a heart that doesn’t pump strongly enough is challenging because there are many potential causes. Standard treatments often block cellular activities rather than enhance them. This is problematic because impaired cellular energy production is a major contributor to reduced heart function. CoQ10 appears effective because it plays a key role in synthesizing adenosine triphosphate (ATP), the molecule responsible for cellular energy. By supporting ATP production, CoQ10 enhances cellular activity rather than suppressing it, giving the heart the energy it needs to function more effectively.
The patients in the study took 100 mg of CoQ10 three times daily for two years. Ubiquinol‑QH by Pure Encapsulations is a high‑quality CoQ10 supplement available in 50 mg and 100 mg strengths, making it easy to replicate the study’s dosing. Ubiquinol‑QH is also desirable because it uses ubiquinol—the most bioavailable, readily absorbed form of CoQ10.
Many CoQ10 products use the ubiquinone form, but the body must convert ubiquinone into ubiquinol before it can be used. This extra step reduces absorption. Click here to learn more about the differences.
