Why Mitochondrial Function Is Foundational to Cellular Health

As the CEO of the cell, the mitochondria handle cellular “facility maintenance” — or the repair, clean-up, and management activities for your body and cells¹ healthy functioning and long-term wellness.^1,2 This maintenance involves two layers:

• Cellular homeostasis: The ongoing quality control mechanisms your cells perform to support healthy growth and development.
• Mitochondrial homeostasis: A subset of cellular homeostasis, just on the mitochondrial level.

While research is ongoing, existing research is clear: healthy mitochondrial function is essential for your long-term cellular health and whole body wellness. The more you understand about mitochondria, the better equipped you are to advance your wellness goals for years to come.

The Relationship Between Ubiquinol and the Mitochondria

Ubiquinol and mitochondria work together to support cellular and whole-body wellness. Before you understand the relationship between the two, you should first understand some of the differences between ubiquinol and CoQ10 and how they interact.

You may have heard of CoQ10 but did you know it comes in two forms? CoQ10, also called “ubiquinone,” and its other form, “ubiquinol,” the active antioxidant form of CoQ10.^3,4 Both are naturally produced in your body, and the efficient conversion of ubiquinone into ubiquinol is a key factor in maintaining healthy mitochondrial and cellular function.

Ubiquinol is especially key to helping your mitochondria maintain cellular homeostasis. It protects against an excess of free radicals, molecules seeking electrons that can damage cells over time and cause premature aging.⁵ Ubiquinol also supports vital cellular energy production, which ensures your organs, like your heart and lungs, maintain proper function.⁶ Learn more about how ubiquinol supports your body’s cellular energy production, thanks to its antioxidant properties.

As we age, especially beginning around age 40, our bodies become less efficient at converting ubiquinone into ubiquinol. Without enough ubiquinol, our cells cannot regenerate and repair as efficiently. Think of your cells like a car headlight: over time, they get foggy with wear and tear, and while they might still work, they need a little extra help to clean them and help them function properly over the years. Ubiquinol plays a foundational role, supporting your cells as they age and encounter daily stressors.

Your body’s naturally occurring ubiquinol is vital for maintaining healthy cellular function, and a daily Kaneka Ubiquinol^® supplement can help you maintain healthy blood levels of ubiquinol, supporting these crucial processes for healthy aging.

Mitochondrial Maintenance: How an Antioxidant Like Ubiquinol Helps

Mitochondria are one of the major sources of free radicals in the body. That’s why ubiquinol’s antioxidant qualities make it the ideal partner for your mitochondria, helping them function normally and protecting against natural wear and tear, like the buildup of excess free radicals.

When you’re prioritizing your cellular health, you should know what these terms mean:

• Free radicals: Molecules that are missing electrons and seek to take them from other molecules, which can cause damage and premature aging.⁷
• Antioxidant: Molecules (like ubiquinol) that give away electrons to free radicals, neutralizing them without being harmed themselves.
• Reactive oxygen species (ROS): A type of free radical containing oxygen; when too many build up in the mitochondria, they can damage the cell.⁸

Understanding these basics helps you appreciate how your lifestyle — eating a balanced diet, staying active, managing stress, and taking the right supplements like Kaneka Ubiquinol^® — can support healthy mitochondrial maintenance.

The Basics of Oxidative Stress

Understanding oxidative stress and free radicals is key to understanding how an antioxidant, like ubiquinol, supports your cellular health. When free radical levels outnumber antioxidant levels, oxidative stress occurs.⁹ This is a normal part of life and aging — free radicals are produced naturally during cellular energy production in the mitochondria. However, external factors like a poor diet, cigarette smoke, car exhaust, and pollution can worsen oxidative stress to unhealthy levels.¹⁰

While some oxidation is necessary for your body’s processes, unmanaged oxidative stress can accelerate aging and impact your overall well-being. The good news? Ubiquinol’s antioxidant properties make it a powerful ally in keeping oxidative stress in check. Learn more about what oxidative stress is and how to protect against it.

The Four Parts of Cellular and Mitochondrial Homeostasis

Cellular and mitochondrial homeostasis might sound complex, but think of it as your body’s version of regular maintenance to stay healthy. There are four main “facility maintenance” processes of cellular homeostasis to know, especially as they relate to ubiquinol and supplements that contain Kaneka Ubiquinol^®:

Fission and Fusion

• Fission: The intentional splitting of one mitochondrion into two, often to remove unusable or damaged parts¹¹
• Fusion: The merging of two mitochondria into one, allowing the recycling of mitochondrial parts and improving energy efficiency

Ubiquinol helps maintain the proper balance of mitochondrial fission and fusion, possibly through its antioxidant properties, though researchers are still exploring other mechanisms and the full extent of its benefits.

Apoptosis

Apoptosis is “programmed cell death”: this may sound concerning, but it’s a natural biological process that safely removes cells that are no longer needed or are functioning poorly. This process can be triggered by age, bacteria, viruses, UV light, or toxins that cause ROS or DNA damage. When apoptosis doesn’t work properly, it can contribute to various health problems.¹²

Mitophagy

Mitophagy is the process by which cells remove damaged mitochondria, safeguarding overall cellular health. If mitophagy doesn’t occur efficiently, damaged mitochondria can accumulate, potentially triggering inflammatory processes and impairing cell function.¹³

Cell Senescence

Cell senescence happens when cells stop growing and enter a dormant state to prevent continued damage, often as a protective measure against further damage.¹⁴ Many triggers can inspire this process, including oxidative stress, DNA damage, inflammation, and pathogens. While dormant, these cells remain active so they can signal to the body’s other systems. Eventually, the body’s immune system clears out these senescent cells, but this process slows with age.

Ubiquinol supports all of these “facility maintenance” processes. As you grow older, however, the body does not convert CoQ10 into ubiquinol as efficiently, and ubiquinol levels naturally decline. Taking a Kaneka Ubiquinol^® supplement can help your cells get the antioxidant support they need.

Supporting the Body’s CEO: Where to Start

Mitochondrial health is the foundation for how the body produces cellular energy, manages cellular function, and ages over time. Every lifestyle choice, from the food on the plate to the supplements in the cabinet, impacts these essential processes.

For those looking to take an active role in supporting their cellular and mitochondrial health, start with a few practical starting points, like:

• maintaining a heart-healthy diet rich in antioxidant nutrients
• staying physically active with regular exercise
• managing stress
• prioritizing quality sleep
• focusing on smart supplementation to support the body’s nutritional needs

Frequently Asked Questions About Mitochondria

What are mitochondria?

Mitochondria are small structures (organelles) found in nearly every cell of the body. They convert the energy from food into ATP, the molecule cells use to power their functions. Beyond cellular energy production, mitochondria also manage cellular repair, waste removal, and function — which is why researchers now call them the “CEO of the cell.”

Why are mitochondria important for heart health?

The heart is one of the most energy-demanding organs in the body and contains a very high concentration of mitochondria.¹⁵ Healthy mitochondrial function is essential for the heart to maintain its rhythm and pump blood effectively.

How does ubiquinol support mitochondrial health?

Ubiquinol is an essential component of the electron transport chain (where ATP is produced). It also acts as an antioxidant that protects mitochondria and DNA from free radical damage caused by oxidative stress. As the body ages, its ability to produce ubiquinol declines, which is one reason many adults over 40 consider a Kaneka Ubiquinol^® supplement.

What is the difference between ubiquinol and CoQ10?

CoQ10 exists in two forms: ubiquinone (the oxidized form) and ubiquinol (the active antioxidant form). The body must convert ubiquinone into ubiquinol before it can be used for energy production and antioxidant defense, but this conversion becomes less efficient with age.
