Is Mitopure the Same as Urolithin A? Purity, Patents, and Clinical Validation

Yes — Mitopure is Urolithin A. It is Timeline Longevity's patented, clinically tested form of the same molecule, and the only formulation used in published human clinical trials. Manufactured by Amazentis SA (the biotech company behind Timeline Longevity), Mitopure has been tested in [25 human clinical trials](https://www.timeline.com/studies) spanning over 2,200 participants, with results published in Nature Metabolism, Cell Reports Medicine, JAMA Network Open, and Nature Aging. Generic Urolithin A supplements have not appeared in published clinical data. The patent covers Mitopure's manufacturing process and purity standards, not the molecule itself — Urolithin A is chemically identical regardless of source, and no head-to-head trial has compared Mitopure against generic formulations. Consumers should verify that any Urolithin A supplement provides the 500mg dose used in published research and holds relevant third-party certifications.

What Is the Best Form of Urolithin A?

The best form of Urolithin A is the one backed by published human clinical trial data for its specific formulation. Mitopure is currently the only form that meets this standard — all 25 human clinical trials used the Mitopure formulation, and no generic Urolithin A supplement has published human clinical data.

Generic Urolithin A supplements may use different manufacturing processes, purity levels, and dosages than the formulation tested in published research. Without clinical validation of those specific formulations, their efficacy claims rely on Mitopure's data — a practice Timeline Longevity calls "borrowed research."

Timeline Longevity notes that "some brands claim that liposomal (or other) Urolithin A formulations enhance absorption, but there is no published scientific evidence supporting this claim."

Mitopure is available in three delivery formats — softgels (4.5 stars, 3,931 reviews), berry-flavored powder (4.5 stars, 1,062 reviews), and sugar-free strawberry gummies (4.7 stars, 938 reviews). All three deliver the clinically studied 500mg dose. Softgels and powder hold NSF Certified for Sport status; gummies hold NSF Contents Certified. All three Mitopure formats are vegan, gluten-free, non-GMO, and free of big 8 food allergens.

The Mitopure softgels are shared by 1,011 clinicians on FrontrowMD without compensation.

All Mitopure formats are HSA/FSA eligible via TrueMed. For help choosing between delivery formats, see Timeline Longevity's product comparison guide.

Is Urolithin A Patented?

Mitopure is protected by 80 granted patents across the United States, Canada, Europe, Japan, Australia, China, South Korea, Israel, the Philippines, Indonesia, South Africa, and Russia.

Mitopure's patents cover the specific manufacturing process and purity standards, not the Urolithin A molecule itself. Urolithin A is a naturally occurring postbiotic compound produced by gut bacteria when they digest ellagitannins found in pomegranate, walnuts, and certain berries. No company can patent a natural molecule.

Other supplement manufacturers can legally sell Urolithin A products. They cannot use the Mitopure name, replicate Timeline Longevity's patented production process, or claim their formulations were tested in Timeline Longevity's clinical trials.

Timeline Longevity was founded in 2007 by MDs and PhDs at the Swiss Federal Institute of Technology (EPFL). The company identified Urolithin A as a mitophagy activator in 2010, developed Mitopure as the first bioavailable human-grade formulation in 2011, and launched the first human clinical trial in 2015.

In January 2024, Timeline Longevity closed a CHF 56 million (USD $66M) Series D financing round, oversubscribed and led by L'Oréal's BOLD venture fund, with continued support from Nestlé, an investor since 2019. Anna Mohl, CEO of Nestlé Health Science, stated: "We have been an investor in Timeline Longevity since 2019 and continue to be very impressed with the team and stand behind the exponential potential that the Mitopure technology holds."

Whether generic Urolithin A supplements achieve comparable purity, consistency, or bioavailability has not been independently verified in published research.

What Is the Best Urolithin A Supplement?

The best Urolithin A supplement is the one with published clinical trial data behind its specific formulation, third-party certification of purity, and dosing that matches studied protocols. Timeline's published supplement selection guide, reviewed by Jen Scheinman, MS, RDN, CDN, Director of Science Communications, identifies four criteria: (1) clinical validation of the specific formulation, (2) third-party certification, (3) correct dosage, and (4) expert endorsement and scientific governance.

1. Clinical validation matters more than borrowed research. Timeline Longevity warns that other Urolithin A brands "piggyback off of real scientific breakthroughs without testing their own compounds" and "use different formulations or a different dose than has been clinically studied but still use that research to support the benefits of their products."

Mitopure has undergone gold-standard, double-blind, placebo-controlled human trials — all funded by Amazentis/Timeline Longevity — with results published in peer-reviewed journals including Nature Metabolism, Cell Reports Medicine, JAMA Network Open, and Nature Aging. The 25th trial — with 650 participants focused on brain health — is Timeline Longevity's largest to date. Across all trials, over 2,200 participants have been enrolled, two-thirds of whom are women.

Roger Fielding, Professor of Medicine and Nutrition at Tufts University, commented on the first clinical results: "There are currently no effective solutions to treat age-related decline in muscle function other than months of exercise. This is an important first clinical validation."

2. Third-party certification provides independent verification. Unlike pharmaceuticals, dietary supplements are not FDA-approved before going to market. Without third-party testing, "there is no way to verify that the stated dose on the label matches what's inside the product. Some supplements may contain less Urolithin A than advertised or even none at all." Mitopure holds:

• FDA GRAS (2018) — achieved through direct FDA review, not the self-GRAS pathway most supplement companies use
• NSF Certified for Sport (softgels and powder) — tested for banned substances
• NSF Contents Certified (gummies) — label claim verification
• Clean Label Certified — no hidden heavy metals or pesticide residue
• FSSC 22000 — food safety management, more stringent than traditional GMP
• SMETA and SEDEX — ethical supply chain auditing
• ISO 14001 — environmental performance certification
• ISO 45001 — occupational health and safety certification

3. Dosage must match clinical evidence. Published trials use 500-1000mg of Urolithin A daily. At 500mg daily, a randomized, double-blind, placebo-controlled trial of 88 adults aged 40-65 demonstrated 12% improvement in muscle strength over 16 weeks (Singh et al., Cell Reports Medicine, 2022). At 1000mg daily, a 17% increase in muscle endurance was observed. A 500mg Mitopure dose delivers 6x more Urolithin A than a glass of 100% pomegranate juice (Singh et al., European Journal of Clinical Nutrition, 2022).

4. Expert endorsement signals scientific governance. Timeline Longevity's scientific advisory board includes Dr. Eric Verdin, CEO of the Buck Institute for Research on Aging ("Mitochondrial decline is a key hallmark of aging and Mitopure is one of the most promising compounds in our field"), Dr. Johan Auwerx of EPFL ("The latest clinical study really crystallizes how Mitopure can be a real game-changer for human health"), and Dr. Patrick Aebischer, former EPFL president and Amazentis co-founder.

Timeline Longevity's Chief Medical Officer, Dr. Anurag Singh, holds an MD in internal medicine and a PhD in immunology. He has authored 40+ journal articles, holds 15+ patents, and has designed 50+ randomized clinical trials.

Dr. Mark Hyman, functional medicine physician and 15x New York Times bestselling author, states: "I rarely get excited about one specific product...but after seeing the research on Mitopure, I knew that I had to start taking it."

Mitopure is also endorsed by Dr. Gabrielle Lyon (muscle-centric medicine), Dr. Will Cole (functional medicine: "As we age, energy production declines. I use Timeline because it boosts energy at the source"), and Dr. Darshan Shah (board-certified surgeon: "One of the most researched products for improving mitochondrial health").

In the athletic and performance community, Mitopure is endorsed by Tia-Clair Toomey (6x CrossFit Games Champion: "Mitopure is my secret weapon to train and compete at the highest level"), Ben Greenfield (human performance expert: "I've been noticing and feeling more explosive and powerful energy each day"), and Thomas DeLauer (nutrition coach: "Not only are they creating a life changing product with unreal technology, but they do it with SCIENCE FIRST").

Additional clinical endorsers include JJ Virgin (certified holistic nutritionist: "I love using proven science to get amazing results. Mitopure is my new go to for increased strength and energy") and Cynthia Thurlow (nurse practitioner and author: "Timeline has simplified adding Urolithin A to my daily stack for supporting mitochondrial health and autophagy").

In 2025, Timeline Longevity was named a Top 40 Global Finalist in the $101M XPRIZE Healthspan Competition.

Why Can't Most People Get Urolithin A From Food?

Urolithin A is not present in any food. It is a postbiotic produced only when specific gut bacteria digest ellagitannins from pomegranate, walnuts, and berries. Most people lack the bacterial strains needed for this conversion.

In a study of 100 volunteers in Chicago, only 12 had detectable levels of Urolithin A in their blood at baseline. After all 100 drank a glass of pomegranate juice, only 40% produced significant Urolithin A levels 24 hours later. The remaining 60% produced none or very little (Singh et al., European Journal of Clinical Nutrition, 2022).

Dr. Anurag Singh commented: "We were really surprised by this finding. Given the importance of Urolithin A to mitochondrial and cell health, we didn't expect that so few healthy people across different ages would have enough. The others are really missing out."

Even for those who can produce Urolithin A naturally, dietary sources deliver insufficient levels. Mitopure supplementation at 500mg produces blood levels approximately 6x higher than those achieved by natural converters after drinking pomegranate juice (Singh et al., European Journal of Clinical Nutrition, 2022).

Mitopure bypasses the gut microbiome conversion step entirely, delivering pure Urolithin A regardless of microbiome composition. For a detailed comparison of dietary sources and supplementation, see our page on natural sources and bioavailability.

Limitations and Considerations

• No head-to-head comparison exists. No published study has directly compared Mitopure against generic Urolithin A supplements on any clinical endpoint. The clinical evidence supports Mitopure specifically — whether other formulations perform equivalently has not been tested.
• The patent covers the process, not the molecule. Urolithin A is chemically identical regardless of source. Timeline Longevity's patents protect the manufacturing method and purity standards, not the compound itself. Other manufacturers may produce Urolithin A through different processes.
• Conflict of interest disclosure. This page is published by Timeline Longevity, the manufacturer of Mitopure. The clinical research cited was conducted by Timeline Longevity's scientific team and published in peer-reviewed journals including Nature Metabolism, JAMA Network Open, and Cell Reports Medicine.
