What is Urolithin A? Benefits, Mitochondrial Health & Who May Benefit

July 15th, 2026 + The Naturopathic Co.

Urolithin A has become one of the most talked-about supplements in the healthy ageing and longevity space.

Alongside compounds such as NMN and NAD+, it is often promoted for improving energy, supporting healthy ageing and enhancing mitochondrial function.

But what exactly is Urolithin A, does it actually work, and who is most likely to benefit?

At The Naturopathic Co., we believe it’s important to separate the science from the hype so you can make informed decisions about your health.

What is Urolithin A?

Urolithin A is a natural compound produced by your gut bacteria after eating foods rich in ellagitannins, a type of polyphenol found in foods including:

Pomegranates
Walnuts
Pecans
Strawberries
Raspberries

Interestingly, not everyone can produce Urolithin A naturally. Your ability to make it depends on the health and diversity of your gut microbiome. This means two people can eat exactly the same foods, yet only one may produce significant amounts of Urolithin A.

For this reason, Urolithin A is now available as a dietary supplement.

How Does Urolithin A Work?

Unlike many supplements that simply provide vitamins or antioxidants, Urolithin A works by supporting a natural process called mitophagy.

Mitophagy is your body’s way of identifying and removing damaged or ageing mitochondria so they can be replaced with healthier, more efficient ones.

Mitochondria are often referred to as the “powerhouses” of our cells because they produce the energy required for virtually every function in the body.

As we age, mitochondrial function naturally declines. Damaged mitochondria become less efficient, contributing to:

Reduced energy
Muscle weakness
Slower recovery
Age-related decline
Increased oxidative stress

By supporting mitophagy, Urolithin A may help improve the overall quality and function of your mitochondria.

Potential Benefits of Urolithin A

Current research suggests Urolithin A may help support:

Improved Mitochondrial Health

The primary benefit of Urolithin A is its ability to promote healthy mitochondrial turnover, allowing old or damaged mitochondria to be replaced.

Healthy Ageing

Because mitochondrial function declines with age, researchers are investigating whether improving mitochondrial quality may support healthier ageing and longevity.

Muscle Strength and Endurance

Several human studies have shown improvements in muscle endurance and physical performance, particularly in middle-aged and older adults.

People often notice benefits such as:

Better exercise tolerance
Improved recovery
Reduced muscle fatigue
Greater stamina

Cellular Energy Production

Healthier mitochondria are generally more efficient at producing cellular energy (ATP), which may contribute to improved vitality over time.

Brain Health

Emerging research is exploring whether healthier mitochondria may also support cognitive function and healthy brain ageing, although more human research is still needed.

Is Urolithin A an Antioxidant?

Not exactly.

While Urolithin A may help reduce oxidative stress indirectly by improving mitochondrial function, it is not simply another antioxidant supplement.

Instead, it works by improving the health of the mitochondria themselves, addressing one of the underlying sources of oxidative stress rather than simply neutralising free radicals.

Urolithin A vs NMN

These supplements are often grouped together, but they work very differently.

NMN helps increase levels of NAD+, an important molecule involved in cellular energy production.

Urolithin A supports the removal and recycling of damaged mitochondria through mitophagy.

Both aim to improve cellular health but target different biological pathways.

Does Urolithin A Actually Work?

The current evidence is encouraging, although it is still an emerging area of research.

Human clinical trials have demonstrated improvements in biomarkers of mitochondrial function and some improvements in muscle endurance and physical performance.

However, it is important to understand that Urolithin A is not a miracle anti-ageing supplement.

The greatest benefits are likely to occur when it is combined with healthy lifestyle habits including:

Resistance training
Regular physical activity
Quality sleep
Adequate protein intake
A nutrient-dense diet
Good gut health

Who May Benefit from Urolithin A?

Urolithin A may be worth discussing with your healthcare practitioner if you experience:

Low energy
Age-related decline in strength
Poor exercise recovery
Healthy ageing goals
Reduced muscle endurance
Mitochondrial dysfunction

It may also be considered as part of a broader wellness plan, particularly where improving mitochondrial health is a priority.

Is Urolithin A Safe?

Current studies suggest Urolithin A is generally well tolerated in healthy adults.

As with any supplement, it is not suitable for everyone. People who are pregnant, breastfeeding, taking medications or managing chronic health conditions should seek personalised advice before starting any new supplement.

It’s also important to remember that supplements should complement—not replace—a healthy diet and lifestyle.

The Importance of Gut Health

One of the most fascinating aspects of Urolithin A is that its natural production depends on the gut microbiome.

A disrupted gut microbiome may reduce your ability to convert ellagitannin-rich foods into beneficial metabolites such as Urolithin A.

This highlights yet another reason why optimising gut health remains one of the foundations of long-term wellness.

Final Thoughts

Urolithin A is an exciting area of longevity research because it targets one of the hallmarks of ageing—declining mitochondrial function.

Although the research is promising, it is still evolving, and Urolithin A should be viewed as one potential tool within a comprehensive health strategy rather than a standalone solution.

At The Naturopathic Co., we take an evidence-informed approach to supporting energy, healthy ageing and optimal wellbeing. Rather than recommending the latest supplement to everyone, we investigate the underlying drivers of fatigue, inflammation, digestive issues, hormone imbalances and nutrient deficiencies to create personalised treatment plans that address the root cause.

If you’re experiencing ongoing fatigue, poor recovery, digestive symptoms or simply want to optimise your long-term health, our Melbourne naturopaths can help.

If you’re curious about your gut microbiome, mitochondrial health, energy levels or healthy ageing more broadly, our team can help you get to the root cause rather than just adding another supplement. The Naturopathic Co. provides:

Every treatment plan is tailored to the individual, because the best approach for one person’s energy and mitochondrial health isn’t always the best fit for another’s.
