Urolithin A for Pickleball Players

Reviewed by SOMA HEALTH's Medical Research Team

Pickleball has become one of the fastest-growing sports in the country, and a large share of its most devoted players are over fifty. The game rewards quick bursts, fast direction changes and long sessions of stop-and-go effort, often several games back to back. That combination is exactly why so many players start thinking seriously about energy and recovery, and why urolithin A has entered the conversation.

Injury-tracking research has followed pickleball's rise closely, noting that participation among older adults has climbed sharply and that the sport's demands, repeated sprints, pivots and reaches, put real load on aging muscles and joints. For players who want to keep showing up three or four times a week and still feel fresh, the underlying question is about how well the body produces and refreshes energy at the cellular level.

Recovery between games starts in the mitochondria

The energy for every sprint to the kitchen line and every reset comes from mitochondria, the structures inside your cells that convert fuel and oxygen into usable energy. How much capacity you have, and how fast you recover between points, games and days, depends heavily on mitochondrial density and quality. As we age, the pool of healthy mitochondria tends to shrink, and the cell's routine for clearing out worn, underperforming mitochondria slows.

That clearing process is called mitophagy: the targeted recycling of damaged mitochondria so the cell can build fresh, capable ones. Efficient mitophagy helps keep the cellular energy supply clean; sluggish mitophagy lets debris accumulate, which can undermine the steady energy and quick recovery a long pickleball session demands. If you want the mechanics, see our mitophagy explainer and our overview of mitochondrial health.

What urolithin A is

Urolithin A is a gut postbiotic. Your gut bacteria make it from ellagitannins found in pomegranates, walnuts and some berries, and you cannot count on getting meaningful amounts from food, because only some people carry the microbes that convert those compounds efficiently. In research, urolithin A acts as a signal that supports mitophagy, which is the reason it has become a compound of interest for muscle endurance, energy and recovery, the traits that matter when you are on game four of the afternoon.

What the human evidence shows

Straight talk on the evidence: urolithin A research is promising but still emerging. A 2024 systematic review in Ageing Research Reviews, focused on targeting aging with urolithin A in humans, concluded that the human evidence is encouraging but still developing. Here is what has actually been studied in people, organized from most established to newest.

Established human findings

Safety and mitochondrial signaling (HUMAN). The first-in-human trial, Andreux and colleagues in Nature Metabolism (2019), found urolithin A safe and well tolerated at doses up to 1,000 mg per day and reported a measurable shift in mitochondrial gene expression in older adults, establishing both a safety ceiling and a plausible biological effect.

Muscle endurance in older adults (HUMAN). Liu, D'Amico and colleagues, in JAMA Network Open (2022), studied older adults over roughly four months and reported an improvement in muscle endurance, the fatigue-resistance quality that keeps your legs under you across back-to-back games.

Strength and exercise performance in midlife (HUMAN). Singh and colleagues in Cell Reports Medicine (2022) tested 500 mg and 1,000 mg daily arms in middle-aged adults over four months and reported benefits in muscle strength and aspects of exercise performance.

Newer human research

Resistance-trained men (HUMAN). An eight-week randomized controlled trial in the Journal of the International Society of Sports Nutrition (2024) examined resistance-trained men, moving the evidence toward already-active people rather than sedentary starting points.

Endurance runners (HUMAN). A 2025 trial in distance runners looked at a trained endurance population, relevant to the repeated-effort nature of a long pickleball session.

Immune-cell mitochondria and inflammaging (HUMAN). A 2025 randomized controlled trial in Nature Aging, over about 28 days, reported that urolithin A supported the mitochondrial health of immune cells in midlife adults, in the context of the low-grade inflammation sometimes called inflammaging. Because recovery has an immune component, this line of work is especially interesting for players managing frequent play.

Preclinical research (labeled as such)

The foundational discoveries are preclinical and should be read that way. Ryu and colleagues in Nature Medicine (2016) showed urolithin A triggered mitophagy, extended lifespan in the worm C. elegans, and improved muscle function in rodents, the origin of the mitophagy-and-muscle story, in models rather than humans. D'Amico and colleagues in Aging Cell (2022) reported joint and cartilage effects in osteoarthritis models, which is preclinical and not a claim about human joints. Given how much pickleball loads the knees, ankles and shoulders, this is an area of early scientific interest, not an established benefit.

Using urolithin A as a pickleball player

Human trials have used 500 to 1,000 mg per day, with 1,000 mg at the top of the tested range and the level used in several strength and performance studies. Urolithin A is not a pre-game stimulant; it will not give you a caffeine-style jolt before you step on court. It is taken consistently, every day, to support the underlying energy machinery. Because the human muscle trials ran roughly two to four months, judge it over weeks, not a single session. Our guides on urolithin A for energy and how long urolithin A takes to work add practical detail.

Treat it as one input alongside the basics that keep older players durable: a proper warm-up, hydration, sensible recovery days, strength work and good footwear. A mitophagy-supporting compound complements that routine, it does not replace it.

An important note: topics such as energy, recovery and joint comfort are described here in structure and function terms only. Urolithin A is not a treatment for any medical condition. Pickleball injuries are common, so if you have joint pain, swelling, or any health concern, see your doctor rather than relying on a supplement.
