Mitochondria and Healthy Aging: How Ubiquinol Helps Patients Live Better, Longer

Thanks to major advances in healthcare and medicine, Americans are living longer than ever. Average life expectancy in the United States rose to 78.4 years in 2023, and recent projections suggest more than 20 percent of the population will be over 65 by 2030. But longer life spans are accompanied by a rise in chronic conditions, including metabolic disturbances, fatigue, muscle loss and heightened risk of serious disease. As research increasingly points to mitochondrial dysfunction as a key driver of age-related decline, mitochondrial support is now considered a powerful strategy for promoting vital aging—and ubiquinol, the active form of CoQ10, is emerging as a prominent player in protecting mitochondria from the ravages of time. Here’s what the science shows.^{1, 2, 3}

The Role of Mitochondria in Healthy Aging.

The complex process of aging impacts human physiology at multiple levels, eliciting changes associated with a variety of age-related conditions and chronic diseases. Over the years, numerous concepts of aging have been put forth, ranging from programmed longevity to free radicals and oxidative stress. The mitochondrial theory—a variant of the free radical postulation—proposes that damage to mitochondria plays a significant role. Since its introduction, a growing body of research has focused on how mitochondria affect aging and longevity.^{4, 5, 6, 7, 8}

While earlier studies focused primarily on cellular respiration and ATP production, mitochondria are currently recognized as far more than the powerhouses of the cells. Emerging evidence confirms the profound influence of mitochondria on human health and the pathogenesis of disease, and mitochondrial dysfunction is now implicated in neurodegenerative disorders, cardiovascular diseases, metabolic syndrome, macular degeneration, autoimmune problems, liver diseases and the development and progression of cancer.^{9, 10, 11, 12, 13}

Various factors, including genetic mutations, environmental toxins, infections and certain medications, can trigger or exacerbate mitochondrial dysfunction. Additionally, the process of aging impacts both the structure and activity of mitochondria, prompting changes marked by DNA mutations, higher levels of reactive oxygen species (ROS), lower ATP production and compromised mitophagy.^{14, 15, 16}

Mitochondrial DNA is especially vulnerable to damage, and mtDNA mutations and deletions accumulate with age the heart, brain, colon, skeletal muscles and other tissues and organs. Age-related reductions in oxidative phosphorylation efficiency and lower ATP production lead to inadequate cellular energy supply, contributing to diminished muscle strength, cognitive impairment and overall declines characteristic of aging. Mitochondrial disruptions and decreased ATP production are associated with increased ROS and additional damage to mitochondria and other cellular components. Mitophagy also slows with age, resulting in the accumulation of dysfunctional mitochondria that further compromises cellular health.^{17, 18, 19, 20, 21, 22, 23, 24}

These aspects of mitochondrial breakdown are thought to accelerate aging and promote the onset of disease: in animal models, mtDNA mutations are linked with various phenotypes of aging, including hair loss, kyphosis, reduced mobility and shortened lifespan. Intracellular levels of ROS are considered a key determinant of lifespan, and mitophagy is known to have a prominent influence on the development and progression of diseases. In humans, mitochondrial dysfunction has been implicated in a wide array of age-related conditions, including neurodegenerative disorders, cardiovascular diseases, metabolic syndrome, diabetes and the initiation and progression of cancer.^{25, 26, 27, 28, 29, 30, 31, 32}

Maintaining Mitochondria: Evidence-Based Strategies.

Because mitochondria are pivotal in the process of aging, maintaining their health is critical for delaying cellular senescence and enhancing longevity. A growing body of research is focusing on mitochondria as a central target for vital aging, and studies suggest diet, lifestyle and supplement strategies aimed at improving mitochondrial function may slow age-related decline, protect against the development and progression of disease and promote a longer, healthier life.^{33, 34, 35, 36, 37, 38, 39}

• The Mito Food Plan—designed for mitochondrial support—avoids high-glycemic foods and emphasizes protein, phytonutrient-rich plant foods and high-quality fats. Caloric restriction, ketogenic diets, intermittent fasting and low-carb regimens appear to reduce oxidative stress, improve ATP production efficiency, encourage mitochondrial biogenesis and potentially increase lifespan.^{40, 41, 42, 43, 44}
• In addition to tailored eating plans, specific nutrients and dietary components have also been shown to support mitochondria. Polyphenols, vitamins C and E, zinc and other antioxidants shield mitochondria from oxidative stress, and several B vitamins are essential cofactors in enzymatic reactions required for producing ATP. Omega-3 fatty acids are known to preserve the fluidity and integrity of mitochondrial membranes, and in studies, magnesium improved mitochondrial function and reduced oxidative stress.^{45, 46, 47, 48, 49, 50}
• Lifestyle influences like physical activity, stress and sleep are equally important. Research links exercise and physical activity with reduced ROS and mtDNA damage, enhanced mitophagy and biogenesis, and increased energy production efficiency. In studies, moderate aerobic exercise improved age-related mitochondrial decline, while endurance training and high-intensity interval training appear to have more pronounced results, especially in older patients.^{51, 52, 53, 54}
• Sleep disturbances likewise impair mitochondrial biogenesis and interrupt their proper function, and long-term sleep deprivation is associated with mitochondrial disruptions, increased ROS production and accumulated mtDNA damage. Other research shows optimizing sleep decreases ROS and may promote mitophagy.^{55, 56, 57, 58}
• Numerous studies also demonstrate the significant adverse effects of psychological stress on mitochondria. Chronic stress impairs mitochondrial function, dysregulates mitophagy and drives ROS production, and over time, ongoing stress is linked with higher incidence of disease and accelerated aging. Stress-management techniques like yoga, meditation and deep breathing practices show promise for maintaining mitochondrial integrity, delaying cellular aging and reducing the risk of disease.^{59, 60, 61, 62}

Along with diet and lifestyle modifications, a targeted supplement protocol can support mitochondria and ensure healthy aging. Research suggests alpha-lipoic acid, NAC+, N-acetyl cysteine, L-carnitine and several other compounds promote mitochondrial function, encourage ATP production, lessen oxidative stress and impede age-related decline. CoQ10 in particular is gaining attention for diseases characterized by mitochondrial dysfunction, including cardiovascular disease, metabolic syndrome and neurodegenerative disorders, as well as skin damage and other markers of aging.^{63, 64, 65, 66, 67, 68, 69}

While CoQ10 is essential for mitochondrial health, levels drop significantly during aging—in some cases, by as much as 50 percent. Commonly used medications like statins and bisphosphonates further deplete CoQ10, underscoring the importance of supplementing. The problem: most CoQ10 supplements occur as ubiquinone, which must be converted by the body to ubiquinol, the active form. But ubiquinone absorption and conversion are slow and limited, and aging hampers the body’s efficiency in absorbing and converting CoQ10, and certain health conditions and diseases also interfere with its bioavailability. Ubiquinol, the reduced, active form of CoQ10, does not require conversion and is more readily absorbed and bioavailable than ubiquinone—critical for older patients. Consequently, a higher percentage is available for cellular use, and in research, ubiquinol supplementation led to significantly greater absorption from the gastrointestinal tract and measurable plasma increases in CoQ10.^{70, 71, 72, 73, 74, 75, 76, 77}

Emerging evidence hints at ubiquinol’s ability to optimize mitochondrial function and support healthy aging. In clinical trials, ubiquinol was shown to decrease ROS, shielding mtDNA, lipids and proteins from oxidative damage. Research suggests ubiquinol activates regulatory proteins like SIRT1 and PGC-1α to stimulates mitochondrial biogenesis and other studies demonstrate its positive effects on cellular energy production, muscle strength, metabolic efficiency and vitality in older adults.^{78, 79, 80, 81, 82, 83, 84, 85}

Ubiquinol also has powerful benefits for heart health, with research highlighting its role in maintaining endothelial function, normalizing blood pressure and improving markers of cardiovascular wellness. Its ability to protect neurons and preserve mitochondrial integrity in the brain suggest its promise as a therapeutic strategy for age-related cognitive decline. Other studies point to ubiquinol’s potential for slowing biological aging, reducing the risk of chronic disease and increasing health span.^{86, 87, 88, 89,90, 91, 92, 93, 94}
