Urolithin A vs CoQ10: Two Different Ways to Support Mitochondria

Mitochondria 101: the power plants that age with you

Mitochondria are the tiny structures inside nearly every cell that turn food and oxygen into usable energy. When people talk about feeling energetic, resilient, or "running out of gas," mitochondrial function is often part of the underlying story. As we move through our 40s, 50s, and 60s, the number and quality of our mitochondria tend to shift, which is why so many health-conscious adults become curious about supporting them.

Two of the most talked-about compounds in this space are Urolithin A and CoQ10 (coenzyme Q10). They are frequently mentioned in the same breath, which leads a lot of people to assume they do the same thing. They do not. Understanding the difference helps you make a more informed decision and have a better conversation with your healthcare provider. For a broader primer, see our guide on how to improve mitochondrial function naturally.

What CoQ10 does: a component of the electron transport chain

To understand CoQ10, picture the electron transport chain, a series of protein complexes embedded in the inner membrane of each mitochondrion. Think of it as a bucket brigade: electrons are passed from one complex to the next, and that hand-off releases the energy your cells capture as ATP, the body's main energy currency.

CoQ10 is one of the carriers in that brigade. In its ubiquinone form it accepts electrons, and in its ubiquinol form it donates them, shuttling back and forth between complexes so the chain keeps moving. In other words, CoQ10 is not a stimulant or a repair crew; it is a working part of the machine that helps existing mitochondria produce energy. It also functions as a fat-soluble antioxidant, helping neutralize some of the reactive byproducts that energy production naturally generates.

CoQ10 levels are often reported to decline with age, and certain medications are discussed in connection with lower CoQ10. This is exactly the kind of nuance worth raising with your own doctor. It is not medical advice, and it is not a reason to change any prescription. If you take medication of any kind, talk to your provider before adding CoQ10 or any supplement.

What Urolithin A does: supporting mitophagy and renewal

Urolithin A works on a different problem. Rather than joining the energy assembly line, it is studied for supporting mitophagy, the cell's built-in process for identifying worn-out or damaged mitochondria and recycling them so fresh ones can take their place. If CoQ10 helps the engine run, mitophagy is closer to routine maintenance that clears out the parts that are no longer pulling their weight. You can read more in our explainer on what mitophagy is.

Urolithin A is a compound your gut bacteria can produce from ellagitannins, the polyphenols found in foods like pomegranates, walnuts, and certain berries. The catch is that not everyone's gut microbiome makes it efficiently, which is part of why it is studied as a direct supplement.

The human research is what makes it notable. A randomized, placebo-controlled study published in Nature Metabolism in 2019 found that Urolithin A was safe in healthy older adults and induced a molecular signature of improved mitochondrial and cellular health (Nature Metabolism, 2019). A 2022 randomized trial in Cell Reports Medicine reported effects on measures of muscle endurance in middle-aged adults (Cell Reports Medicine, 2022). More recently, work published in Nature Aging in 2025 has continued to examine Urolithin A in the context of muscle and mitochondrial health with aging (Nature Aging, 2025). To go deeper, see our overview of Urolithin A.

Side-by-side: Urolithin A vs CoQ10

Feature	Urolithin A	CoQ10 (ubiquinone / ubiquinol)
Role in the cell	Mitochondrial quality control; supports renewal	Working component of the energy-production machinery
Mechanism	Studied for supporting mitophagy, the clearing and recycling of damaged mitochondria	Carries electrons in the electron transport chain; acts as a fat-soluble antioxidant
Focus	Helps the body clear out mitochondria that no longer work well	Helps existing mitochondria keep producing energy
Human evidence	Randomized, placebo-controlled trials in healthy and middle-aged adults	Long-studied in mitochondrial biology, exercise, and medication-associated research
Studied dose	Commonly studied around 500 to 1,000 mg per day	Frequently studied in the ~100 to 200 mg per day range (varies widely by study)
Best-studied outcomes	Markers of mitochondrial health; muscle endurance measures	Cellular energy support; antioxidant activity

Doses above reflect ranges reported in research and are not a recommendation. Your appropriate intake, if any, is a conversation for you and your healthcare provider.

Do they compete, or complement each other?

Because they act on different stages of the mitochondrial life cycle, Urolithin A and CoQ10 are often framed as complementary rather than interchangeable. One supports the ongoing work of energy production and antioxidant defense; the other is studied for supporting the housekeeping that keeps the overall mitochondrial population healthier over time. Supporting both the "run it" side and the "renew it" side is an intuitive framework, and it mirrors how many people think about mitochondrial health more broadly, including its relationship to everyday energy (see mitochondria and fatigue).

That said, "complementary in theory" is not the same as "proven better together" in rigorous head-to-head trials. If you are considering either compound, or both, the responsible move is to speak with a healthcare provider first, especially if you take any medication, have a health condition, or are pregnant or nursing. This is particularly true when combining supplements, since interactions and individual needs vary.

If mitophagy support is your priority, our SOMA Urolithin A gummies deliver a studied-range dose in a simple daily format. As always, use them as part of an overall routine you have discussed with your provider.

Frequently asked questions

Is Urolithin A the same as CoQ10?

No. CoQ10 is a component of the electron transport chain that helps existing mitochondria produce energy and acts as an antioxidant. Urolithin A is studied for supporting mitophagy, the clearing and renewal of damaged mitochondria. They target different parts of mitochondrial health.

Can I take Urolithin A and CoQ10 together?

Because they work through different mechanisms, some people view them as complementary. However, combining supplements is exactly the situation where you should talk to your healthcare provider first, particularly if you take medication or have any health condition.

Why do people mention CoQ10 and certain medications?

CoQ10 is sometimes discussed in the context of certain medications and of natural age-related decline. That is a conversation to have with your own doctor. It is not medical advice, and nothing here is intended to diagnose, treat, or replace guidance from your provider.

Does my body already make Urolithin A?

Some people's gut bacteria produce Urolithin A from polyphenols in foods like pomegranates and walnuts, but many people convert it inefficiently. That variability is part of why it is studied as a direct supplement rather than relying on diet alone.

Which one should I choose?

It depends on your goals, your diet, your medications, and your provider's guidance. CoQ10 leans toward supporting energy production and antioxidant defense; Urolithin A leans toward supporting mitochondrial quality control and renewal. There is no one-size-fits-all answer, so make the decision with a qualified professional.
