Coenzyme Q10 is tremendously important for the functioning of the entire body. It's a substance that operates at the cellular level, influencing proper cell development. Most importantly, it participates in energy production within cells, protects them from the negative effects of free radicals, and improves cellular oxygenation. While ubiquinone is the most commonly used form of CoQ10, ubiquinol is actually the superior and more effective form.
What Is Ubiquinol?
Coenzyme Q10 typically appears on the market in two forms: ubiquinone and ubiquinol. Most dietary supplements contain the less effective form—ubiquinone. This form is poorly absorbed by the body, meaning that even significant amounts in supplements don't guarantee your body will receive adequate levels of this coenzyme.
Furthermore, after ingestion, the body must convert ubiquinone into ubiquinol—the most biologically active form of CoQ10. Ubiquinol is therefore the reduced (electron-rich) form of coenzyme Q10, making it significantly easier to absorb. This offers not only health benefits but also economic advantages, as smaller quantities of tablets are needed for effective supplementation.
[tip:Research suggests that ubiquinol allows for approximately 8 times greater CoQ10 absorption compared to standard ubiquinone supplements. This makes it particularly valuable for those over 40, when the body's ability to convert ubiquinone to ubiquinol naturally declines.]
Ubiquinol typically comes in soft gel capsule form. Not only are these easy to swallow, but they also dissolve quickly, allowing the liquid CoQ10 to be rapidly and fully absorbed by the body.
Ubiquinone vs Ubiquinol: Understanding the Difference
To understand why ubiquinol is superior, it helps to know how these two forms relate:
- Ubiquinone – the oxidised form of CoQ10, must be converted by the body before use
- Ubiquinol – the reduced (active) form, ready for immediate use by cells
Young, healthy individuals typically convert ubiquinone to ubiquinol efficiently. However, this conversion ability decreases with age, stress, illness, and certain medications—particularly statins. For these individuals, supplementing directly with ubiquinol bypasses the conversion step entirely, ensuring the body receives the active form it needs.
[note:After approximately age 40, the body's natural CoQ10 production and conversion efficiency begin to decline. This is one reason why ubiquinol supplementation becomes increasingly valuable as we age.]
What Does Ubiquinol Affect?
Ubiquinol primarily works at the cellular level. It participates directly in the process of proton and electron transfer and serves as a fundamental element of the respiratory chain within mitochondria. It's present throughout the body, supporting metabolic processes that account for approximately 95% of our body's energy needs—energy required for proper nutrient absorption, cleansing, wound healing, and maintaining muscle strength.
Heart and Cardiovascular Health
Ubiquinol has the greatest significance for the heart and skeletal system. The heart, with its constant pumping action, has the highest energy demands of any organ—and therefore the highest CoQ10 requirements. Deficiency can lead to serious complications, including cardiovascular problems.
Muscle and Nervous System Function
Insufficient CoQ10 can significantly weaken limb muscle function, reduce nervous system efficiency, and disrupt the proper course of metabolic and tissue regeneration processes. In extreme cases, it may also affect immune system function.

How Does Ubiquinol Work?
Generally speaking, ubiquinol provides energy to cells—and thereby to the entire body. However, its influence on the human body is far greater than it might initially appear. Ubiquinol offers multiple benefits:
Powerful Antioxidant Protection
As a natural antioxidant, ubiquinol provides protection against oxidative stress and the harmful effects of free radicals. It also activates other substances with similar protective actions. An undeniable advantage is its ability to reduce visible signs of ageing by protecting cells from oxidative damage.
Cardiovascular Support
Ubiquinol improves blood circulation and heart efficiency, thereby supporting the maintenance of healthy blood pressure. The heart muscle contains more CoQ10 than any other tissue, reflecting its critical importance for cardiac function.
Nervous System Support
Ubiquinol supports proper nervous system function, particularly by counteracting the negative effects of cholesterol-lowering medications. Statins, while effective for cholesterol management, can deplete CoQ10 levels—including in the brain. Ubiquinol provides the brain and nervous system with the energy needed for proper function.
[warning:If you're taking statin medications for cholesterol, consult your healthcare provider about CoQ10 supplementation. Statins can significantly reduce the body's CoQ10 levels, and supplementation—particularly with ubiquinol—may help offset this effect.]
Male Fertility Support
Ubiquinol may improve fertility in men, as there's a clear relationship between CoQ10 levels and sperm concentration in semen. Ubiquinol thereby improves semen quality, potentially increasing chances of conception.
Athletic Performance
Ubiquinol supports athletes and physically active individuals. It not only helps achieve better sports performance but also improves overall mood and reduces fatigue. Many athletes report improved endurance and faster recovery when supplementing with ubiquinol.
Fatigue and Muscle Support
Ubiquinol protects against fatigue, weakness, and muscle pain—symptoms that can indicate CoQ10 deficiency. By supporting cellular energy production, it helps maintain vitality throughout the day.

Who Should Consider Ubiquinol?
Ubiquinol supplementation may be particularly beneficial for:
- Adults over 40 – when natural CoQ10 production and conversion efficiency decline
- Those taking statins – to counteract CoQ10 depletion caused by these medications
- People with cardiovascular concerns – to support heart health and energy
- Athletes and active individuals – for enhanced performance and recovery
- Anyone experiencing chronic fatigue – to support cellular energy production
- Men concerned about fertility – to support sperm quality and motility
- Those seeking anti-ageing support – for its powerful antioxidant properties
Dosage Considerations
Typical ubiquinol doses range from 50-200 mg daily, depending on individual needs and health goals. For general wellness support, 100 mg daily is common. Higher doses (200 mg or more) may be appropriate for those with specific cardiovascular concerns or taking statins—always under healthcare provider guidance.
Because ubiquinol is fat-soluble, it's best absorbed when taken with a meal containing healthy fats. The soft gel form, which contains the active ingredient suspended in oil, further enhances absorption.
Key Takeaway: Ubiquinol is the active, ready-to-use form of Coenzyme Q10 that offers significantly better absorption than standard ubiquinone—up to 8 times more effective. From cellular energy production to heart health, antioxidant protection to athletic performance, ubiquinol supports the body's most fundamental processes. For anyone over 40, taking statins, or seeking optimal CoQ10 benefits, ubiquinol represents the superior choice for supplementation.
