Urolithin A with CoQ10
Urolithin A and coenzyme Q10 are both described as mitochondrial ingredients, and both show up in routines built around energy and healthy aging. But they support the mitochondria in genuinely different ways. This guide explains what each one does, what the human evidence actually shows for each, and how to think about using them together without overstating the case.
Two ingredients, two different jobs
It is tempting to lump urolithin A and CoQ10 together because they both touch mitochondria, the compartments inside your cells that turn food and oxygen into usable energy. In practice they work at different points in the life cycle of a mitochondrion. CoQ10 is a working part inside the machinery, while urolithin A is involved in maintaining and renewing the machinery itself. Understanding that distinction is the whole point of pairing them thoughtfully rather than assuming they are interchangeable.
What CoQ10 does
Coenzyme Q10, also called ubiquinone, is a fat-soluble compound your body makes on its own. It sits in the inner mitochondrial membrane and acts as an electron carrier in the electron transport chain, the series of steps that ultimately produces most of the cell's energy currency. It also functions as an antioxidant that helps protect cell membranes. Your body converts between two forms, ubiquinone and the reduced form ubiquinol, as it does this work.
Endogenous CoQ10 production tends to decline with age, and levels can also be lower in people taking statin medications, because the same biochemical pathway that makes cholesterol also contributes to CoQ10 synthesis. That is the practical reason many people consider supplementing it. As a structure/function ingredient, CoQ10 supports normal mitochondrial energy production and provides antioxidant support. It is a well-characterized nutrient, but supplementing it is not a treatment for any medical condition, and anyone on statins or other prescriptions should talk with their own clinician before adding it.
What urolithin A does, and what the human evidence shows
Urolithin A takes a different route. It is a gut postbiotic: your microbiome makes it from ellagitannins, the compounds found in pomegranate, walnuts and certain berries. Notably, only some people carry the gut bacteria needed to convert those precursors efficiently, which is a large part of why a standardized supplement exists at all. Its most-studied action is support for mitophagy, the cellular housekeeping process that identifies worn-out mitochondria and recycles them so newer, better-functioning ones can take their place. Where CoQ10 helps the existing machinery run, urolithin A is associated with keeping the pool of machinery in good repair.
Proven in humans
The human record for urolithin A is the strongest part of its story, and it is worth being precise about it. The first-in-human study (Andreux and colleagues, Nature Metabolism, 2019) reported that urolithin A was safe and well tolerated at doses up to 1,000 mg per day and produced a mitochondrial gene-expression signature in muscle. In middle-aged adults, a randomized trial (Singh and colleagues, Cell Reports Medicine, 2022) tested 500 mg and 1,000 mg arms over four months and reported improvements in measures of muscle strength and exercise performance. In older adults, a randomized study (Liu and D'Amico and colleagues, JAMA Network Open, 2022) reported improvements in muscle endurance over roughly four months. An eight-week randomized trial in resistance-trained men (Journal of the International Society of Sports Nutrition, 2024) added to the exercise picture.
Newer human research
More recent human work has looked beyond muscle. A 2025 randomized trial (Nature Aging) over about 28 days reported that urolithin A supported the mitochondrial health of immune cells in midlife adults, a line of research connected to the concept of inflammaging. A 2025 trial in distance runners has also been published. At the same time, a 2024 systematic review in Ageing Research Reviews on targeting aging with urolithin A in humans concluded that the overall evidence is still emerging, which is the honest framing to keep in mind.
Preclinical background
Much of the original mechanistic work is preclinical and should be labeled that way. The foundational study (Ryu and colleagues, Nature Medicine, 2016) demonstrated that urolithin A induced mitophagy and extended lifespan in the worm C. elegans and improved muscle measures in rodents. Preclinical models have also explored joint and cartilage endpoints (D'Amico and colleagues, Aging Cell, 2022). Areas like skin, gut, brain and heart remain early, preclinical exploration rather than established human outcomes.
Why people pair urolithin A and CoQ10
The logic behind combining them is complementary rather than redundant. CoQ10 supports the energy-producing machinery that is currently running; urolithin A supports the renewal of that machinery through mitophagy. In principle these are non-overlapping angles on mitochondrial support, which is why the two often appear in the same longevity-minded routine. To be clear about the limits, though: there is no large human trial that tested this exact combination and measured a combined benefit. The human evidence for urolithin A stands on urolithin A studies; the case for CoQ10 stands on CoQ10 research. Pairing them is a reasonable, evidence-informed choice, not a proven synergy.
How to take them together
If you decide to use both, a few practical points help. Urolithin A has been studied at 500 to 1,000 mg per day, with 1,000 mg representing the top of that range; see our urolithin A dosage guide for detail. CoQ10 is fat-soluble, so it is generally taken with a meal that contains some fat for better absorption; taking urolithin A with the same meal is convenient and reasonable. Consistency matters more than timing for both, because these are maintenance-style ingredients rather than acute stimulants. If you want the broader picture of how urolithin A fits into a routine, our urolithin A guide and our overview of mitochondrial health are good starting points, and if the mitophagy concept is new to you, see what is mitophagy.
Honest limitations
Neither ingredient is a shortcut, and neither treats disease. Urolithin A's human evidence is most developed for muscle strength, endurance and exercise performance, with newer work extending into immune-cell mitochondrial health; other applications remain preclinical. CoQ10 is well-studied as a nutrient, but supplement effects vary by individual and baseline status. Combining two supplements does not multiply benefits, and more is not automatically better. If you have a medical condition, take prescription medication such as a statin, or are pregnant or nursing, talk with a qualified healthcare provider before starting either.

Frequently asked questions
Do urolithin A and CoQ10 do the same thing?
No. CoQ10 is an electron carrier that supports the mitochondrial energy machinery that is currently running. Urolithin A is associated with mitophagy, the recycling of worn-out mitochondria. They support mitochondria from different angles, which is why some people use them together.
Can I take them at the same time?
There is no known reason they cannot be taken together, and taking both with the same meal is convenient. CoQ10 absorbs better with dietary fat. Consistency day to day matters more than exact timing for both.
Is there a human study proving the combination works?
No large human trial has tested this specific pairing and measured a combined benefit. The human evidence for urolithin A comes from urolithin A trials, and the case for CoQ10 comes from CoQ10 research. Pairing them is evidence-informed, not a proven synergy.
How much urolithin A is worth taking?
Human studies used 500 to 1,000 mg per day, with 1,000 mg at the top of that range. SOMA HEALTH Urolithin A Gummies provide 1,000 mg per 4-gummy daily serving.
Why do people on statins consider CoQ10?
The pathway that makes cholesterol also contributes to CoQ10 synthesis, so statin users can have lower CoQ10 levels. This is a common reason people ask about it, but anyone on statins should discuss supplements with their own clinician first.
Does everyone make urolithin A on their own?
No. Your gut bacteria make it from ellagitannins in foods like pomegranate and walnuts, but only some microbiomes convert it efficiently. That variability is a key reason a standardized supplement exists.
Which should I choose if I only want one?
That depends on your goals and what your healthcare provider advises. Urolithin A has the more developed human evidence base for muscle strength and endurance; CoQ10 is a long-established nutrient for energy-machinery support. There is no universal answer.
