Best Urolithin A Supplements (2026)
Bottom line
In our scoring, Urolithin A rates mixed evidence: the evidence is mixed for muscle strength. Our top-scored product is Urolithin A 500mg (84/100), about $1.10 a day at a clinical dose of 500 mg/day is the studied floor. Bottom line: promising but not settled, so manage expectations. This is our opinion, not medical advice; talk to your clinician before starting.
Urolithin A is one of the few genuinely new supplement ingredients that arrived with real human trials attached: 500 mg a day has improved muscle strength and endurance in randomized trials, mostly in older and middle-aged adults, by supporting mitochondrial quality. Our full urolithin A scorecard covers the evidence in depth; for buyers, the whole decision comes down to one question - is the branded, trial-validated material (Timeline Mitopure) worth roughly four times a generic that delivers the same 500 mg molecule? For most people, no. Because it protects muscle and mitochondria, it is also a sensible companion to protein and creatine during rapid weight loss - see our GLP-1 supplement guide and healthy aging picks.
The Verdict
The best urolithin A for most people is Double Wood Urolithin A: the clinical 500 mg dose from a GMP facility at about $1.10 a day, roughly a quarter of the branded price. The best value is aeternum Urolithin A at about $0.98 a day, the lowest cost per clinical dose we found. If you want the exact trial-validated material with independent sport certification, Timeline Mitopure is the gold-standard pick (NSF Certified for Sport) - but at about $4.17 a day it is only worth it if that pedigree specifically matters to you. Skip the 1,500 mg-plus label claims and the diacetate form, and take whichever you choose with a fatty meal.

Detailed Reviews
Urolithin A 500mg
Capsule (250 mg x 2) | 500mg/serving | 30 servings
The cleanest budget way to take the clinically studied molecule at the clinical dose. In our view this is the sensible default for most people who want urolithin A without paying the branded premium.
Urolithin A 500mg
Capsule (500 mg each) | 500mg/serving | 60 servings
The lowest cost-per-dose option for pure urolithin A. The brand's ISO 17025 testing claim is a reasonable signal, though it is not independently listed the way USP or NSF products are.
Mitopure Urolithin A Softgels
Softgel (Mitopure branded urolithin A) | 500mg/serving | 30 servings
The gold-standard material with real third-party sport certification. In our view the quality is genuine, but the price is only justifiable if the trial pedigree or NSF certification specifically matters to you.

Full score breakdownWhat to Look For When Buying
- ✓500 mg per day is the clinical dose used in the trials; 1,000 mg was used for endurance endpoints
- ✓Ignore 1,500 mg and 2,000 mg label claims - they exceed anything tested in humans and are inflation, not a better dose
- ✓Mitopure is the exact material used in the studies and the only NSF Certified for Sport option, but you pay a large premium for it
- ✓A GMP-made generic delivers the same 500 mg of urolithin A for a fraction of the price
- ✓Avoid urolithin A diacetate - it is a different form than the one validated in the trials
- ✓Take it with a meal containing fat; urolithin A is fat-soluble and absorbs better with food
- ✓Watch combination products - some deliver only 250 mg of urolithin A per serving, half the clinical dose
Frequently Asked Questions
What is urolithin A and where does it come from?
Urolithin A is a compound your gut bacteria produce from ellagitannins, which are found in pomegranates, berries, walnuts, and some teas. It is technically a postbiotic (a beneficial molecule made by gut microbes). Only an estimated 30-40% of people carry the specific bacteria needed to produce meaningful amounts, which is why it is sold as a supplement - taking it directly bypasses the need for the right gut microbiome.
Does urolithin A actually work?
For muscle strength and endurance, the evidence is genuinely promising: multiple randomized controlled trials at 500-1,000 mg/day have shown improvements in muscle strength, endurance, and mitochondrial biomarkers, mostly in older and middle-aged adults. It is more established than most novel longevity ingredients. But several trials missed their primary endpoints, and no study has shown it extends lifespan or reverses aging, so it is best described as a well-supported muscle and mitochondrial-health ingredient rather than a proven anti-aging compound.
Is Timeline Mitopure worth the extra money over a generic?
Mitopure is the exact urolithin A material used in the human trials and is the only option here that is NSF Certified for Sport, which matters if you are a tested athlete or want maximum dosing confidence in a new ingredient. But it costs roughly four times a generic that delivers the same 500 mg of urolithin A. In our view, if you simply want the clinically studied molecule at the clinical dose, a GMP-made generic like Double Wood delivers it at a fraction of the price. The premium buys the trial pedigree and third-party sport certification, which is a defensible but steep upgrade.
How much urolithin A should I take?
500 mg per day is the dose used in most human trials and the practical floor for a benefit. Trials targeting muscle endurance used 1,000 mg/day. Doses of 1,500 mg or 2,000 mg that some products advertise exceed anything tested in humans and are label inflation, not a better dose. Take it with food that contains fat for better absorption.
Can I just eat pomegranates instead of taking a supplement?
Only if your gut bacteria can convert the ellagitannins into urolithin A, and roughly 60-70% of people cannot produce a meaningful amount no matter how much pomegranate they eat. If you are a non-producer, eating the fruit gives you the fiber and polyphenols but little urolithin A. A supplement delivers the finished molecule directly, which is the whole point of it existing as a product.
