Urolithin A for Energy and Mitochondrial Health
Share
Urolithin A (UA) is a natural compound produced by our gut microbiome when we consume foods rich in ellagitannins, a type of polyphenol found in pomegranates, berries, and nuts. In simple terms, when you eat a pomegranate, beneficial gut bacteria (if present) can convert its polyphenols into Urolithin A (Direct supplementation with Urolithin A overcomes limitations of dietary exposure and gut microbiome variability in healthy adults to achieve consistent levels across the population | European Journal of Clinical Nutrition).
Why all the excitement about this molecule? It turns out UA is a powerhouse for cellular health. It triggers a process called mitophagy, which is like a spring cleaning for your cells’ mitochondria. Mitochondria are the “energy factories” in cells, and mitophagy is the removal of old, dysfunctional mitochondria so that new, efficient ones can take their place (Urolithin A induces mitophagy and prolongs lifespan in C. elegans and increases muscle function in rodents | Nature Medicine). By promoting this renewal process, Urolithin A helps keep your mitochondria youthful and efficient at producing ATP (cellular energy).
In animal studies, UA’s effects have been dramatic, it extended lifespan in worms and improved muscle function in aging mice (Urolithin A induces mitophagy and prolongs lifespan in C. elegans and increases muscle function in rodents | Nature Medicine). Human research is now confirming benefits as well: short-term clinical trials showed that UA is safe and can induce a “molecular signature” of improved mitochondrial health (for example, enhancing the expression of genes that help mitochondria work better) (The mitophagy activator urolithin A is safe and induces a molecular signature of improved mitochondrial and cellular health in humans - PubMed). In essence, Urolithin A works by rejuvenating your cells’ energy generators, which can translate into better cellular energy production, endurance, and vitality.
The Problem with Relying on Pomegranates
It might sound like you could get Urolithin A simply by drinking pomegranate juice or eating walnuts. However, there’s a catch, not everyone’s gut bacteria can make this conversion. In fact, studies show only about 40% of people have the right microbiome composition to naturally convert ellagitannins from pomegranates into significant amounts of Urolithin A (Individual gut microbiome responses to pomegranate overcome by direct urolithin A supplementation). Even among those lucky 40%, the amount of UA produced can vary widely and is often quite low. Diet alone may not yield enough UA to realize its full benefits. One clinical study illustrated this clearly: drinking an 8-ounce glass of 100% pomegranate juice raised blood levels of Urolithin A, but taking a 500 mg UA supplement raised levels six times higher than the juice (Individual gut microbiome responses to pomegranate overcome by direct urolithin A supplementation). In other words, even if you eat pomegranate daily, you might not reach the effective dose of UA that supplementation can provide. Additionally, modern lifestyles and diets might not consistently include ellagitannin-rich foods every single day. This is where a supplement becomes valuable. By taking Urolithin A in a purified form, you bypass the dependency on gut bacteria and food sources, ensuring your body gets a reliable, clinically relevant dose of this beneficial molecule. (For example, EO Vita’s Urolithin A product offers a convenient daily dose of UA without any guesswork, though any high-quality UA supplement can serve the purpose.) The bottom line: pomegranates are healthy, but for reaping Urolithin A’s benefits, direct supplementation is often the most effective and practical approach.
(File:Pomegranate fruit - whole and piece with arils.jpg - Wikibooks, open books for an open world) Pomegranates contain ellagitannins that can convert to Urolithin A, but not everyone’s gut can make this conversion efficiently. Only around 40% of people have the necessary gut microbes to produce Urolithin A from dietary polyphenols (Individual gut microbiome responses to pomegranate overcome by direct urolithin A supplementation). Even those who do may get only modest levels, one study found a 500 mg Urolithin A supplement resulted in 6× higher UA levels in the bloodstream than an 8 oz serving of pomegranate juice (Individual gut microbiome responses to pomegranate overcome by direct urolithin A supplementation). This makes direct supplementation a more reliable way to obtain beneficial amounts of Urolithin A for most individuals.
Key Benefits of Urolithin A Supplementation
Thanks to emerging scientific research, we now have a clearer picture of what Urolithin A can do for our health. Here are the top evidence-backed benefits of Urolithin A supplementation:
-
Enhanced Mitochondrial Function and Energy: Urolithin A helps your cells produce energy more efficiently. By clearing out defective mitochondria and stimulating the growth of healthy ones, UA essentially “tunes up” your cellular engines (Urolithin A: The Promise and Reality of a Gut Metabolite). The result is often an increase in ATP production (the energy currency of cells) and better endurance. In fact, research has found UA promotes the formation of new mitochondrial respiratory chain proteins, boosting ATP synthesis in muscle cells ( Pharmacological Effects of Urolithin A and Its Role in Muscle Health and Performance: Current Knowledge and Prospects - PMC ). Many users report feeling less fatigue and more day-to-day energy after a few weeks of taking UA, likely because their cells are literally producing energy more effectively.
-
Improved Muscle Strength and Endurance: Whether you’re an athlete or just staying active, Urolithin A can benefit your muscles. In a 4-month randomized trial with middle-aged adults, those taking Urolithin A significantly increased their muscle strength (~12% higher than the placebo group) ( Urolithin A improves muscle strength, exercise performance, and biomarkers of mitochondrial health in a randomized trial in middle-aged adults ). They also showed improvements in aerobic endurance and physical performance tests compared to placebo ( Urolithin A improves muscle strength, exercise performance, and biomarkers of mitochondrial health in a randomized trial in middle-aged adults ). What’s remarkable is that these benefits occurred without any changes in exercise routine, suggesting UA was enhancing muscle cellular function directly. Other studies confirm that UA bolsters muscle endurance, for example, older adults supplementing with UA were able to sustain muscle contractions longer before fatigue ( Effect of Urolithin A Supplementation on Muscle Endurance and Mitochondrial Health in Older Adults: A Randomized Clinical Trial - PMC ). So, taking UA might help you squeeze out an extra rep in the gym or finish that long hike with a bit more ease, thanks to more resilient muscle mitochondria.

Supports Healthy Aging of Cells: Urolithin A is making waves in the longevity science community because of its potential anti-aging effects. By activating mitophagy (mitochondrial cleanup), UA addresses one of the root causes of cellular aging: the buildup of dysfunctional mitochondria. As we age, our natural mitophagy declines, leading to tired cells and organs. Urolithin A helps reverse this trend, keeping cells “biologically younger.” Lab studies have shown it can extend lifespan in organisms like worms by improving mitochondrial health (Urolithin A induces mitophagy and prolongs lifespan in C. elegans and increases muscle function in rodents | Nature Medicine). More tangibly for us, older adults who took Urolithin A have better muscle endurance and walk farther, indicating a slowing of age-related decline (Urolithin A: The Promise and Reality of a Gut Metabolite) ( Effect of Urolithin A Supplementation on Muscle Endurance and Mitochondrial Health in Older Adults: A Randomized Clinical Trial - PMC ). UA also seems to reduce markers of cellular aging, like inflammation (one trial noted lower C-reactive protein and other inflammatory molecules in UA users) ( Effect of Urolithin A Supplementation on Muscle Endurance and Mitochondrial Health in Older Adults: A Randomized Clinical Trial - PMC ). All of this has earned Urolithin A the label of a promising “geroprotective” compound, a fancy way to say it helps protect against the effects of aging at the cellular level (Urolithin A: A Novel Geroprotectant Capable of Stimulating Mitophagy).

Antioxidant and Anti-Inflammatory Effects: Another benefit of Urolithin A is its ability to lower oxidative stress and inflammation in the body. Excess free radicals and chronic inflammation contribute to fatigue, muscle soreness, and numerous health issues. Urolithin A has been shown to activate our internal antioxidant pathways (like the NRF2 pathway) and increase levels of glutathione and other antioxidants ( Pharmacological Effects of Urolithin A and Its Role in Muscle Health and Performance: Current Knowledge and Prospects - PMC ). It also can reduce the release of pro-inflammatory cytokines (immune signals) such as TNF-α and IL-1β, which are associated with “inflammaging” (the inflammation that comes with aging) (Urolithin A: The Promise and Reality of a Gut Metabolite). By doing so, UA helps create a more balanced, less inflamed environment in the body. Practically, this might mean faster recovery from exercise, less joint stiffness, and a lower long-term risk of chronic diseases associated with inflammation. While UA isn’t a replacement for eating antioxidant-rich fruits and veggies, it provides a targeted boost to the body’s defense system against oxidative stress.
Combining Urolithin A with Other Supplements
Urolithin A works at the mitochondrial level, and it can be complemented by other nutrients that support cellular energy and healthy aging. Many health enthusiasts are now pairing UA with supplements such as:
-
Coenzyme Q10 (CoQ10): CoQ10 is a crucial part of the mitochondrial energy production chain. It helps shuttle electrons within mitochondria to generate ATP. By taking CoQ10 alongside Urolithin A, you support mitochondrial function from two angles,UA improves the quality and turnover of mitochondria, and CoQ10 ensures those mitochondria have the cofactor they need to produce energy. This one-two punch can be especially helpful for energy levels and endurance.
-
NAD⁺ Boosters (e.g. NR or NMN): NAD⁺ is a molecule essential for metabolism and mitochondrial activity. Levels of NAD⁺ decline with age. Supplements like nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN) aim to raise NAD⁺ levels. Pairing them with Urolithin A could synergistically enhance mitochondrial health,UA improves mitochondrial quality while NAD boosters improve mitochondrial quantity and function. Some early research suggests combining NAD precursors with therapies that improve mitophagy might amplify benefits in terms of fatigue reduction and cell health.
-
Resveratrol or Polyphenols: Resveratrol is another compound famous for activating certain longevity pathways (like SIRT1) and supporting mitochondrial function. While resveratrol works differently from Urolithin A, taking them together could provide a broader spectrum of cellular protection. In fact, some advanced formulations combine UA with resveratrol and other polyphenols to maximize their collective antioxidant and anti-aging effects. Similarly, quercetin, PQQ, or sulforaphane are other bioactive compounds that could complement UA by promoting mitochondrial biogenesis or reducing oxidative stress.
-
Protein or Amino Acids (for muscle health): If your goal is muscle maintenance or growth (especially relevant for fitness enthusiasts), remember that Urolithin A helps improve muscle endurance and fatigue resistance, but it doesn’t directly build muscle mass on its own (Urolithin A: The Promise and Reality of a Gut Metabolite). So, it pairs well with adequate protein intake or branched-chain amino acid supplements to provide the building blocks for muscle repair. Think of UA as improving the engine of the muscle, while protein provides the bricks and mortar for the muscle structure. Together, they support overall muscle health and performance.
When combining supplements, it’s always wise to introduce one at a time and consult with a healthcare provider, especially if you have any medical conditions. Urolithin A on its own is generally well tolerated (studies up to 1000 mg daily for months report no significant side effects ( Effect of Urolithin A Supplementation on Muscle Endurance and Mitochondrial Health in Older Adults: A Randomized Clinical Trial - PMC )), and it doesn’t typically interfere with other common supplements. EO VITA’s Urolithin A can be seamlessly added to your daily regimen and may even come in formulations that include some of the complementary ingredients mentioned above. By stacking UA with the right partners, you can create a comprehensive strategy for better energy, healthy aging, and overall vitality.
Get Started with Urolithin A Supplementation
Urolithin A represents an exciting convergence of nutrition and cutting-edge science. For the general health enthusiast, it offers a tangible way to upgrade your cellular health,leading to improvements you can feel, like enhanced energy and endurance, and improvements you can’t see, like rejuvenated mitochondria and slower cellular aging. While eating ellagitannin-rich fruits (like pomegranates) is healthy for many reasons, relying on them alone won’t guarantee you significant Urolithin A due to individual differences in gut bacteria. Supplementation fills that gap by providing a consistent dose of this powerhouse molecule. Consider Urolithin A as a foundational supplement for mitochondrial health; it can stand on its own or act as the backbone of a broader supplement stack geared toward longevity and energy. And remember, a supplement is most effective when paired with a healthy lifestyle, balanced diet, regular exercise, and adequate sleep. Urolithin A is not a magic bullet, but as research is unveiling, it’s certainly a valuable tool in the wellness toolkit. By supporting your body at the cellular level, it helps you feel and function at your best, both now and in the years to come.
