CoQ10 (Coenzyme Q10) is a naturally occurring antioxidant in the human body that plays a vital role in cellular energy production and cardiovascular protection. In this article, we’ll explore what CoQ10 is, how it works, and why supplementing with CoQ10 may be essential for maintaining long-term heart health.
What Is CoQ10? An Overview of Coenzyme Q10
CoQ10, also known as Coenzyme Q10 or ubiquinone, is a vitamin-like compound found naturally in nearly every cell of the human body. It was first discovered in 1957 by Professor Frederick Crane and named “ubiquinone” due to its widespread presence (ubiquitous) in nature.
CoQ10 exists in two primary forms:
- Ubiquinone – the oxidized form
- Ubiquinol – the reduced, biologically active form with higher antioxidant potency
The body can synthesize CoQ10 from amino acids and B-group vitamins. However, natural production declines with age. CoQ10 can also be obtained from dietary sources such as red meat, fatty fish (salmon, tuna), organ meats, nuts, seeds, and vegetables like broccoli and spinach.
Scientific research shows that CoQ10 concentrations are highest in organs with high energy demands, including the heart, liver, kidneys, and skeletal muscles. The heart—an organ that never rests—contains particularly high levels of CoQ10 to support continuous energy production and contraction.
Beyond its antioxidant capacity, CoQ10 is directly involved in cellular energy generation. A deficiency may lead to fatigue, impaired cardiovascular function, and an increased risk of chronic diseases. This is why CoQ10 has become increasingly popular in preventive healthcare, especially among middle-aged and older adults.

How CoQ10 Works in the Body
CoQ10 primarily functions inside the mitochondria—the “power plants” of our cells. It acts as a key electron carrier in the mitochondrial electron transport chain, helping convert nutrients from food into ATP (adenosine triphosphate), the body’s main energy currency.
Specifically, CoQ10 transfers electrons from Complex I and II to Complex III, contributing to the proton gradient required for ATP synthesis through oxidative phosphorylation. According to Crane (2001), CoQ10 is indispensable for converting energy from carbohydrates and fatty acids into usable cellular energy.
In addition to energy production, CoQ10 is a powerful lipid-soluble antioxidant. It protects cell membranes from free radical damage, prevents LDL (“bad cholesterol”) oxidation—a major contributor to atherosclerosis—and helps regenerate other antioxidants such as vitamin E, strengthening the body’s overall defense system.
In its ubiquinol form, CoQ10 is particularly effective at neutralizing free radicals, especially in the heart, where oxidative stress and energy demand are at their highest.

The Essential Role of CoQ10 in Cardiovascular Health
1. Supports Energy Production in Heart Muscle
CoQ10 is a critical electron carrier in mitochondria, enabling the production of ATP—the fuel required for heart contractions. A CoQ10 deficiency reduces ATP output, leading to weakened cardiac function and persistent fatigue, particularly in people with heart failure.
2. Powerful Antioxidant Protection for Blood Vessels
As a lipid-soluble antioxidant, CoQ10 neutralizes reactive oxygen species (ROS), prevents LDL oxidation, and reduces plaque formation in arteries. This helps maintain vascular elasticity, reduce endothelial inflammation, and promote smoother blood flow.
3. Improves Symptoms and Reduces Cardiovascular Events
Supplementation with CoQ10 has been shown to improve heart failure symptoms (NYHA classification), enhance exercise capacity, and reduce serious outcomes such as hospitalization and cardiovascular mortality. It is especially beneficial for people taking statins, which can deplete CoQ10 levels and cause muscle pain.
4. Supports Heart Health as You Age
Natural CoQ10 levels decline by approximately 50% between the ages of 20 and 80, increasing cardiovascular risk in older adults. Maintaining adequate CoQ10 levels helps reduce cardiac workload, boost overall energy, and prevent age-related heart conditions.
