Want to Keep Up With Younger Colleagues? Support Energy

Reviewed by SOMA HEALTH's Medical Research Team

If you have caught yourself watching a colleague fifteen years younger power through a late afternoon while you are quietly flagging, you are not imagining it. Everyday energy tends to shift with age, and while a supplement is not a shortcut past that, understanding why it happens, and where urolithin A fits, can help you support your vitality intelligently.

Let us be clear about the goal of this page. It is not to sell you a fear about aging or promise that a gummy will turn back the clock. It is to look calmly at what changes in the body's energy machinery over time, what urolithin A has and has not been shown to support in humans, and how to think about it as one piece of a larger routine that includes sleep, movement, and nutrition.

Why energy can feel different with age

A meaningful part of how energetic you feel traces back to your mitochondria, the tiny structures inside nearly every cell that convert nutrients and oxygen into usable energy. As we age, the body's ability to keep its mitochondrial population in good repair tends to become less efficient. Worn-out mitochondria are not always cleared and replaced as briskly as they once were, and the cumulative effect can show up as the sense that the same workday costs a little more than it used to.

The cellular clean-up process that identifies and recycles damaged mitochondria is called mitophagy. Think of it as quality control for your cellular power plants. When mitophagy runs well, cells retain a healthier pool of functioning mitochondria. This is the biology at the center of urolithin A research, and it is worth understanding before reaching for any product. Our primer on mitochondrial health explains the system in plain language, and what mitophagy is goes a level deeper.

Where urolithin A fits

Urolithin A is a gut postbiotic. When you eat foods rich in ellagitannins, chiefly pomegranate, walnuts, and some berries, certain gut bacteria can convert them into urolithin A. The wrinkle is that only some people carry the microbes needed to make it in meaningful amounts, so diet alone produces inconsistent levels from person to person. That variability is precisely why a standardized supplement exists: it delivers a known dose regardless of what your gut can produce. For the full background, see our urolithin A guide.

What draws people focused on everyday stamina to urolithin A is its studied role in supporting mitophagy. By supporting that recycling process, the research explores whether cells can maintain a healthier mitochondrial pool over time. It is a structure and function idea, supporting a normal biological process, rather than a claim to treat fatigue as a medical condition.

What the human evidence shows

Start with the proven human findings. Urolithin A was first tested in people in a 2019 study in Nature Metabolism (Andreux), which found it safe and well tolerated at doses up to 1,000 mg per day and detected a mitochondrial gene-expression signature, an early sign that the compound was engaging the machinery it was designed to. A randomized trial in middle-aged adults in Cell Reports Medicine (Singh 2022), using 500 mg and 1,000 mg daily arms over four months, reported improvements in muscle strength and exercise performance. In older adults, a randomized trial in JAMA Network Open (Liu and D'Amico 2022) reported improved muscle endurance over about four months. These endurance and performance findings are the closest the human evidence comes to the everyday stamina people are often chasing.

Newer human work adds useful context. A 2025 randomized trial in Nature Aging, run over roughly 28 days, reported that urolithin A supported immune-cell mitochondrial health in midlife adults, in the setting of age-related, low-grade inflammation sometimes called inflammaging. An 8-week randomized trial in resistance-trained men (Journal of the International Society of Sports Nutrition, 2024) and a 2025 trial in distance runners extend the picture into fitter, active populations. Taken together, the human data cluster around muscle, endurance, exercise performance, and mitochondrial markers, with a consistent safety record across studies lasting up to about four months. Our page on urolithin A for energy unpacks this further.

Honest limitations

Two limits deserve emphasis. First, urolithin A is not a stimulant. It does not deliver the acute, caffeine-like lift you might associate with pushing through a slump; its research is about supporting cellular processes over weeks and months. If you want an instant afternoon jolt, this is the wrong tool. Second, much of the popular excitement about urolithin A leans on areas that are still early. Laboratory and animal research, meaning preclinical work not yet confirmed in humans, has explored mitophagy and lifespan in the worm C. elegans and muscle benefits in rodents (Ryu 2016, Nature Medicine). Broader ideas around brain and heart energy remain in early, preclinical research. A 2024 systematic review in Ageing Research Reviews concluded that the human evidence for targeting aging with urolithin A is still emerging, which is the honest frame to hold.

Just as important: persistent tiredness is not something to explain away with a supplement. Ongoing fatigue can have real medical causes, from thyroid issues to sleep disorders to anemia, and it deserves a proper look. This guide is educational and is not a treatment. If low energy is interfering with your life, please see your doctor rather than self-managing it.

Practical ways to support everyday energy

A supplement works best inside good fundamentals, not instead of them. Prioritize consistent sleep, since mitochondrial repair and recovery lean heavily on it. Keep moving, because both endurance and resistance exercise are among the most reliable ways to support mitochondrial function; the urolithin A trials themselves were often set against a backdrop of physical activity. Eat with your energy system in mind, including whole foods and the pomegranate, walnut, and berry sources of ellagitannins, even if you also supplement. And if you do add urolithin A, treat it like an experiment: the studied range is 500 to 1,000 mg per day, take it consistently, and judge it over a couple of months rather than a couple of days, since the muscle and endurance trials ran for roughly four months. Our notes on how to take urolithin A cover timing and consistency.
