Best Urolithin A Supplements in the US (2026 Buyer's Guide)

We compared the Urolithin A supplements actually available in the US on the things that matter: dose versus the clinical research, purity and third-party testing, manufacturing transparency, and real cost per day. Here's what we recommend and why, including our own and the competitors we respect.

Urolithin A is one of the most exciting compounds in longevity research right now — and also one of the most expensive, most confusing, and most uneven supplement categories on the shelf. Prices run from under $30 to over $125 for what is, chemically, the same molecule. Some bottles contain exactly what they claim. Some contain a fraction of it. A few contain almost none.

We're Mt. Angel Vitamins, part of Highland Laboratories. We've been manufacturing supplements in Mt. Angel, Oregon for more than 50 years, and we make our own Urolithin A in-house at our FDA-registered, cGMP-certified facility. So here's the honesty pledge up front: yes, one of the products on this list is ours. We think it's the best value for most people, and we'll show you exactly why. But the most clinically studied form of Urolithin A isn't ours — it's Timeline's Mitopure — and we'll tell you when that matters more than price. We publish this guide because earning your trust beats winning a single sale.

This guide ranks real US-available products on dose, purity, testing, manufacturing, and cost per day. If you want the science first, start with what Urolithin A actually is and does and come back. If you're ready to buy, keep reading.

What Actually Makes a Urolithin A Supplement Worth Buying

Before ranking anything, here are the six criteria we use. If a product fails any of them, no amount of marketing makes up the gap. Dose that matches the research. The human trials used 500 mg and 1,000 mg of Urolithin A per day (Singh et al., 2022, the ATLAS trial). 500 mg is the standard daily dose and captures the large majority of the measured benefit. If a product gives you 100–250 mg, or won't disclose the milligrams, it isn't delivering what was studied. For exactly where the benefits plateau, see our dose-response analysis.

It's actually Urolithin A, not a precursor. This is the trap. Plenty of products marketed around Urolithin A actually contain pomegranate extract or ellagic acid — the precursors your gut has to convert, which most people can't do efficiently. If you want Urolithin A, the label must say "Urolithin A" with a milligram amount.

Third-party testing and verified purity. This matters more in Urolithin A than almost any other category, because independent testing has found big gaps between label and bottle. A 2024 National University of Singapore analysis found commercial Urolithin A supplements deviated from their labeled amounts by roughly −15.5% to +28.6%, and across the broader set of "longevity" supplements tested, some contained essentially none of the active ingredient (Sandalova et al., 2024, GeroScience). Translation: with UA, "trust me" isn't good enough. You want per-batch testing and, ideally, published results.

Single ingredient vs. stack. A clean single-ingredient Urolithin A lets you know exactly what you're getting and control your dose. A "longevity blend" (UA plus resveratrol, CoQ10, NMN, etc.) can be convenient, but blends sometimes bury a token amount of the expensive ingredient. Both have a place. Just read the actual UA milligrams, not the front of the label.

Manufacturing transparency. Where and how it's made. A brand that manufactures and tests in its own FDA-registered, cGMP facility can stand behind every batch. A brand that contract-packs through an unnamed facility, or exists only as an Amazon listing with no address, can't give you the same accountability.

Real cost per day. Bottle price is noise. What matters is cost per day at the clinical 500 mg dose, factoring in how many capsules a serving takes and how many days the bottle lasts. A $125 bottle that lasts 30 days is very different economics from a $79.99 bottle that lasts 60.

The Best Urolithin A Supplements, Ranked by Use Case

We're going to call this honestly. One pick wins on overall value (ours). One wins on clinical pedigree (Timeline's). The rest are honest picks for specific needs. Nobody wins everything.

Best Overall Value for Most People — Mt. Angel Vitamins Urolithin A 500 mg (M3200)

Form: Cellulose capsule. UA per serving: 500 mg in a single capsule (one cap = full clinical daily dose). UA form: High-purity Urolithin A, single ingredient. Other ingredients: Cellulose (capsule shell), brown rice protein, vegetable stearates. No soy, gluten, wheat, milk, egg, sugar, starch, or preservatives. Supply: 60 capsules = 60-day supply. Testing / manufacturing: Manufactured, bottled, and tested in-house at Highland Laboratories in Mt. Angel, Oregon. FDA-registered, cGMP-certified, UL and NPA audited, every batch third-party tested. 50+ years in operation. Approx cost/day: ~$1.33 (one-time $79.99) or ~$1.07 (subscribe & save 20%, $63.99). Price last checked Nov 2025.

What we like: It hits the clinically studied 500 mg dose in a single capsule, where most competitors need two — or, in Pure Encapsulations' case, four. It's a clean single ingredient with nothing hidden behind a blend. It's made and tested under one roof in our own Oregon facility, with every batch verified — exactly the accountability the label-accuracy research says this category needs. And at roughly $1.33 a day (less on subscription), it's the lowest cost per day among the credible clinical-dose options. A bottle lasts two months, not one.

What could be better: In full candor, it's high-purity generic Urolithin A, not Timeline's branded Mitopure, which is the specific form used in the published trials (more on that next). It also isn't NSF Certified for Sport, and it's sold direct rather than on every shelf. If "exact studied branded form with a sport cert" is your priority over value, Timeline is your pick.

Best for: Most people who want the clinical dose, clean and verified, at an honest daily cost, from a manufacturer that actually makes it.

Best Clinically-Validated Form — Timeline Mitopure (Softgels)

Form: Vegan softgels (also sold as powder and gummies). UA per serving: 500 mg of Mitopure = 2 softgels daily. UA form: Mitopure — Timeline's proprietary, clinically validated form of Urolithin A. This is the form used in the published human trials. Supply: 60 softgels = 30-day supply (2/day). Testing / certifications: NSF Certified for Sport, Clean Label Project Verified, vegan, non-GMO, made in the USA with globally sourced ingredients. Approx cost/day: ~$4.17 one-time ($125/30 days); ~$2.83–$3.75 on subscription ($85–$112.50/month depending on commitment). Price last checked Nov 2025.

What we like: Credit where it's earned. Mitopure is the form behind most of the human research on Urolithin A, backed by 15+ years of work, dozens of patents, and multiple gold-standard clinical trials. If you want to take precisely what was studied, this is it. NSF Certified for Sport is a meaningful third-party assurance, especially for competitive athletes who get tested.

What could be better: It's the most expensive option by a wide margin — two to three times our cost per day. It takes two softgels to reach 500 mg, the bottle lasts 30 days instead of 60, and it's contract-manufactured with globally sourced ingredients rather than made in Timeline's own facility.

Best for: People who want the exact branded form used in the trials, athletes who need NSF Sport certification, and buyers for whom that pedigree outweighs price.

Best All-in-One Longevity Stack — Codeage Liposomal Urolithin A

Form: Liposomal capsules. UA per serving: 500 mg of Urolithin A per 2-capsule serving, plus trans-resveratrol, betaine, CoQ10, and ellagitannins. Supply: 60 capsules = 30-day supply (2/day). Testing: NSF Contents Certified / third-party tested (label content, contaminants, pesticides, heavy metals, GMP manufacturing, annual re-testing). Manufacturing: Made in the USA in a partner cGMP-certified facility with globally sourced ingredients (not Codeage's own plant). Approx cost/day: ~$3.33/day one-time ($99.99 / 30 servings); ~$2.83–$3.00/day on Subscribe & Save ($84.99–$89.99). Amazon pricing last checked Nov 2025.

What we like: If you'd rather take one product than build a longevity stack from four bottles, this bundles 500 mg of UA with resveratrol, CoQ10, and betaine, using liposomal delivery aimed at absorption. NSF Contents Certified is a meaningful third-party signal in a category where label accuracy is the central problem. Reasonable one-and-done for people already interested in the broader longevity-ingredient category.

What could be better: With any blend, watch the actual UA milligrams and remember you're paying for the whole formula, not just the UA. The added ingredients have their own (separate, mixed) evidence bases. The 2-capsule daily serving means the bottle lasts 30 days, not 60, and per-day cost runs roughly 2× ours. If you specifically want clean, controllable Urolithin A, a single-ingredient product is simpler.

Best for: People who want a longevity combo in a single product and like the idea of stacking UA with resveratrol and CoQ10 — with third-party label verification baked in.

Best Practitioner-Grade / Hypoallergenic — Pure Encapsulations Renual

Form: Caplique capsules (soft wood-cellulose based). UA per serving: 250 mg of Mitopure Urolithin A per 2-capsule label serving, plus trans-resveratrol (from Japanese knotweed) and fermentation-derived CoQ10. Note: the label serving delivers 250 mg of UA — reaching the clinically studied 500 mg dose requires 4 capsules per day. UA form: Mitopure-branded Urolithin A (synthetic, same form as Timeline). Not a liposomal preparation. Supply: 60 caplique capsules = 30 label servings, or 15 days at the clinical 500 mg/day dose. Testing / manufacturing: Pure Encapsulations states it manufactures in its own facility (brand-level quality claim, not lot-specific disclosure); strong hypoallergenic and practitioner-grade QC reputation. Approx cost/day: ~$2.43/day at the 250 mg label serving; ~$4.87/day at the clinical 500 mg/day dose (based on $73 bottle, 30 label servings or 15 true 500 mg servings). Price last checked Nov 2025.

What we like: Pure Encapsulations is a long-trusted practitioner-channel brand with a strong reputation for hypoallergenic, clean formulations and tight quality control, and Renual uses the same Mitopure-branded UA backed by the published trials — paired with resveratrol and CoQ10 in a single formula. If you already buy Pure Encaps through a provider or value that brand's testing standards, Renual is a credible, professional-grade choice.

What could be better: The label serving only delivers half the clinically studied dose. To match the 500 mg used in the human trials you need 4 capsules a day, which roughly doubles the cost-per-day math and burns through a bottle in two weeks. At ~$4.87/day for the clinical dose, it's the priciest option on this list once you actually hit 500 mg. Availability also skews toward practitioner/clinic channels.

Best for: People who buy through a healthcare practitioner, want the Mitopure-branded form paired with resveratrol + CoQ10, and are comfortable with the premium cost — or who genuinely only want a 250 mg daily dose.

Best Budget-Credible Pick (Tested, Under ~$60) — Perpetua.Life Urolithin A Liposomal

Form: Liposomal capsules. UA per serving: 1,000 mg = 2 capsules (so ~500 mg per single capsule, giving easy dose flexibility). Posted potency COA from Harken Research (batch JBK2560112) measured 1,003.49 mg of Urolithin A per 2-capsule serving via HPLC. Testing: Posted third-party potency COA (Harken Research, finished-product capsule testing by HPLC). Note: only potency is publicly posted — no heavy-metal, microbiological, or pesticide panels have been published, so this is narrower than a full third-party panel. Manufacturing: Owned-facility status not verified; Perpetua.Life presents as a US-based R&D / startup brand, and the posted COA lists Harken Research as the testing lab with "Light Labs" as the client — consistent with outsourced or partner manufacturing rather than an owned plant. Approx cost/day: Roughly $1/day or less at the 500 mg (1-capsule) dose; lower on subscription. Price last checked Nov 2025.

What we like: It's one of the few lower-cost options that publishes a third-party potency COA — and the posted result (1,003 mg per 2-cap serving) lands almost exactly on label, which is rare in this category. Because a 1,000 mg serving is two capsules, you can take one capsule for the studied 500 mg dose and stretch a bottle to two months, which is genuinely good economics.

What could be better: The published COA covers potency only, not heavy metals, microbiology, or pesticides — so the "third-party tested" claim is narrower than it can sound. Smaller brand footprint than Timeline or Pure Encaps, no owned-facility transparency, and liposomal claims in general are easier to market than to prove. Still, on tested-and-affordable, it's a reasonable entry point.

Best for: Budget-conscious buyers who refuse to gamble on an untested cheapie, want dose flexibility, and are satisfied with a published potency COA.

Red Flags: How to Not Waste Your Money on Urolithin A

Pomegranate or ellagic acid sold as Urolithin A. The single most common trap. These are precursors, not the finished compound, and most people's gut can't convert them efficiently. If the label doesn't say "Urolithin A" with a milligram amount, you may be buying expensive pomegranate powder.

No third-party testing in a category that badly needs it. This is the big one for UA specifically. Independent analysis has found commercial Urolithin A supplements off their labeled amounts by −15.5% to +28.6%, and in the wider longevity-supplement set, some products contained essentially none of what they claimed (Sandalova et al., 2024, GeroScience). With a raw material this expensive, underdosing and degradation are real and documented. Per-batch third-party testing isn't a nice-to-have here — it's the whole game. And when a brand does post a COA, check what it actually covers: potency-only is better than nothing, but it's not the same as a full panel that also verifies heavy metals, microbiology, and pesticides.

Suspiciously cheap "Urolithin A." Urolithin A is one of the priciest raw materials in supplements. A bottle that undercuts the credible market by a lot is usually either underdosed, a precursor in disguise, or untested. Cheap is fine; cheap-and-unverified is how you end up with the −100% products from the studies.

Proprietary blends hiding the UA dose — or label servings that hide the real cost. If a "cellular energy blend" won't tell you exactly how many milligrams of Urolithin A you're getting, assume it's the smallest amount they could get away with putting on the front of the label. Equally important: always compute your cost at the clinically studied 500 mg/day, not at the brand's label serving. A product that looks reasonably priced at "250 mg per serving" can quietly become the most expensive option on the shelf once you double up to hit the studied dose.

Amazon-only brands with no traceable manufacturer. No address, no facility, no team — just a listing. You have no way to verify any quality claim, and this category is exactly where that bites.

"Clinically proven" claims that borrow Timeline's research. Most published UA research used Mitopure specifically. A generic brand (ours included) can honestly say it delivers the same studied dose of the same molecule, but no brand should imply it ran those trials itself. Watch for products that blur that line.
