What Is Urolithin A?
Urolithin A is a postbiotic — a compound your body produces when gut bacteria transform ellagitannins, found in foods like pomegranates, walnuts, and berries. It has gained attention for its ability to trigger mitophagy — the renewal of damaged mitochondria — which supports energy, muscle function, and healthy aging (NIH PMC).
Evidence-Backed Benefits
1) Mitochondrial Health
- Urolithin A promotes mitophagy, clearing out old mitochondria so new ones can form (PubMed).
- Better mitochondrial function means more energy at the cellular level.
2) Muscle Strength & Endurance
- Clinical studies show Urolithin A supplementation improves muscle function and endurance in older adults (PubMed).
- Helps counteract age-related muscle decline by improving energy efficiency.
3) Longevity & Healthy Aging
- By reducing mitochondrial dysfunction, Urolithin A may slow cellular aging.
- Supports vitality, resilience, and long-term health span.
Dosage & How to Take
- Typical dose: 250–500 mg daily, based on clinical trials.
- Food sources: Pomegranates, walnuts, and berries can help produce Urolithin A naturally — though not everyone’s microbiome can convert it efficiently.
- Absorption tip: Supplements guarantee consistent levels where diet alone may not.
Reference: NIH review on Urolithin A.
Safety & Side Effects
- Generally safe and well tolerated in clinical studies up to 1,000 mg daily.
- No major adverse effects reported in human trials.

FAQs
What foods contain Urolithin A?
It’s not found directly in foods. Instead, your gut bacteria convert ellagitannins from pomegranates, walnuts, and berries into Urolithin A.
Can everyone produce Urolithin A naturally?
No. Production depends on your gut microbiome — only about 30–40% of people efficiently make it from food sources.
Is Urolithin A safe to supplement?
Yes. Human clinical trials show it is safe and well tolerated up to 1,000 mg/day.
Does it help with aging?
Yes. By improving mitochondrial quality and muscle function, Urolithin A supports healthy aging and energy over time.
How long until I notice results?
Muscle function improvements were observed after 4–8 weeks of consistent supplementation in clinical trials.
Conclusion
Urolithin A is more than a nutrient — it’s a cellular rejuvenator. By renewing mitochondria, it supports energy, strength, and longevity. Add it to your wellness arsenal and fuel your journey with the endurance of a Viking.
