Best Urolithin A Brand 2026: How the Top Sellers Compare
Urolithin A has gone from a niche research compound to a crowded shelf, and the brands now selling it differ more in format and philosophy than in the underlying science. This roundup compares five names people search for most, Timeline, Pure Encapsulations, Youth & Earth, Genex, and SOMA HEALTH, on the things that are actually verifiable: format, dose, and testing. It is not a ranking of one true winner, because the right brand depends on what you want from the product.
Disclosure up front: SOMA HEALTH is one of the brands compared here, so this is not a disinterested review, we are a competitor to the other four. To keep it fair, we stick to objective attributes, we do not quote competitor prices or unverified doses, and where a specification is not confirmed we say to check the current label. Prices and formulas change, so always verify on the brand's own page before buying.
The science is shared; the packaging is not
Every brand below is selling the same active compound. Urolithin A is a postbiotic your gut bacteria produce from ellagitannins in pomegranates, walnuts, and certain berries, and only some microbiomes convert it efficiently, which is why a direct supplement appeals to so many. Its best-studied mechanism is support for mitophagy, the recycling of worn-out mitochondria that helps cells maintain healthier energy production. Because the ingredient is shared, brand differences come down to how much they give you, in what form, and how well they prove what is in the bottle.
Proven in humans
The first-in-human study (Andreux and colleagues, Nature Metabolism, 2019) found urolithin A safe and well tolerated up to 1,000 mg per day, with a mitochondrial gene-expression signature in muscle. A randomized trial in older adults (Liu, D'Amico and colleagues, JAMA Network Open, 2022) over about four months reported improved muscle endurance. Singh and colleagues (Cell Reports Medicine, 2022) studied middle-aged adults for four months across 500 mg and 1,000 mg arms and found benefits to muscle strength and exercise performance. A 2025 Nature Aging trial over roughly 28 days reported support for immune-cell mitochondrial health in midlife adults. Trials in 2024 and 2025 in resistance-trained men and distance runners add to the human record.
Still preclinical
The original mitophagy and lifespan findings (Ryu and colleagues, Nature Medicine, 2016) came from C. elegans and rodents. Joint and cartilage work (D'Amico and colleagues, Aging Cell, 2022) used osteoarthritis models. Claims about skin, gut, brain, and heart reflect early, preclinical research that is still exploring possibilities. A 2024 systematic review in Ageing Research Reviews called the human aging evidence still emerging. No brand can honestly promise more than the human data supports, and any that does is a reason for caution.
The brands, compared on what is verifiable
Timeline (Mitopure)
Timeline popularized urolithin A and sells it under its branded, purified Mitopure form. It offers the widest range of formats, including softgels, a powder, and gummies, which makes it a natural starting point for people who want choice. It is the reference brand most others are measured against. For exact dose per serving in each format, check the current label, since Timeline sells several products.
Pure Encapsulations (Renual)
Pure Encapsulations is a practitioner-oriented brand known for tightly controlled, hypoallergenic formulas. Its urolithin A product, Renual, is sold as capsules and positioned around muscle function, cellular energy, and mitochondrial health. It suits people who prefer a clinical, capsule-based brand often recommended through healthcare practitioners. Confirm the per-serving dose on the current label.
Youth & Earth
Youth & Earth sells a liposomal urolithin A in capsule form, marketed at 500 mg per serving with a liposomal delivery system intended to aid absorption, in a vegan formula. It appeals to buyers who specifically want a liposomal capsule and a lower single dose. As always, verify the current label, since formulas are periodically updated.
Genex
Genex is a direct-to-consumer supplement brand that sells urolithin A in capsule form, typically found through online marketplaces. It fits shoppers comfortable buying capsules online who want a straightforward option. Because marketplace listings vary, check the current label for the exact dose and testing details before ordering.
SOMA HEALTH
SOMA HEALTH takes the gummy route with a specific goal: deliver the top of the studied dose in a format people will actually take daily. The SOMA HEALTH Urolithin A Gummies provide 1,000 mg per four-gummy daily serving, are sugar-free and raspberry flavored, come 120 gummies to a 30-day bag, and are third-party tested on every batch. The trade-off is format: it is a gummy, not a capsule or softgel, which suits people who dislike pills and want the full studied dose.
How to choose between them
Start with format, because that is what you will live with daily: capsule brands like Pure Encapsulations, Youth & Earth, and Genex suit pill-takers, while Timeline and SOMA HEALTH offer gummies. Then check the dose per full serving against the studied 500 to 1,000 mg range, rather than the number on the front of the bottle. Finally, insist on third-party testing, because urolithin A is an isolated compound and an independent lab check tells you the label is accurate. Price matters too, but since it changes constantly, compare it yourself at the moment of purchase rather than trusting any static list.

An honest word on limitations
No brand has cracked something the others have not; they are packaging the same compound with different priorities. The human evidence, while genuinely promising for muscle and mitochondrial and immune-cell markers, is still emerging, and the broader longevity claims you see in marketing lean on preclinical work. Urolithin A is a structure and function supplement, not a treatment for any disease. If you are managing a health condition or take medication, talk with your healthcare provider before starting, and treat any brand's marketing as marketing, not medical advice.
Frequently asked questions
Which urolithin A brand is best?
There is no single best brand, because they differ mainly in format and dose rather than in the active compound. Choose based on whether you want a capsule, softgel, or gummy, whether the per-serving dose reaches the studied 500 to 1,000 mg range, and whether the product is third-party tested. Verify each on the current label.
Do these brands use the same urolithin A?
They all sell urolithin A, though the exact source and form can differ, for example Timeline uses its branded Mitopure form and Youth & Earth uses a liposomal delivery. The compound is the same; the delivery system, purity claims, and dose vary. Check each label for specifics.
Why is SOMA HEALTH included in its own comparison?
Because being transparent is better than pretending we are neutral. SOMA HEALTH is a competitor to the other brands listed. We limited the comparison to verifiable attributes, format, dose, and testing, and we do not quote competitor prices or unverified doses, telling you to check the current label instead.
What dose should I look for?
Human trials studied 500 mg and 1,000 mg per day, with 1,000 mg at the top of the range. Compare the dose per full daily serving, not per capsule or gummy, since brands split doses differently. A product below the studied range may deliver less than the research suggests.
How important is third-party testing?
Very. Urolithin A is an isolated ingredient, so an independent lab verifying identity and purity is your main assurance the label is accurate. Prefer brands that test every batch and will share a certificate of analysis. SOMA HEALTH third-party tests each batch; confirm the testing policy of any other brand you consider.
Is urolithin A safe across these brands?
The first-in-human study found urolithin A safe and well tolerated up to 1,000 mg per day, and later trials reported good tolerability. Individual responses vary, and quality depends on the brand. See our side effects guide and speak with your healthcare provider before starting, especially if pregnant, nursing, or on medication.
