Renue By Science Urolithin A Review

Renue By Science is a real brand that sells urolithin A, and it deserves a fair, criteria-based look. This review judges it the same way we would judge anyone — on dose, testing, format, and value — and grounds every claim about the ingredient in published human and preclinical research.

A transparency note first

SOMA HEALTH sells its own urolithin A gummy, so we are a competitor of Renue By Science, not a neutral referee. We think the honest thing to do is tell you that up front and then apply a consistent, transparent scorecard rather than a sales pitch. We will not quote Renue By Science's specific prices or per-serving doses here, because those can change and we have not independently confirmed the current figures this run — for anything specific, check the current label on their own product page. What we can do is give you the framework to evaluate their urolithin A confidently on your own.

What Renue By Science makes

Renue By Science is a longevity-focused supplement company that offers a urolithin A product (marketed within its cellular-health range). Like every urolithin A supplement, the active molecule is identical to what any other brand uses — urolithin A is a single, defined compound, and no company owns a special version of it. The meaningful differences are always the same four levers: how much you get per serving, how it is delivered, how well it is tested, and what it costs per gram per day. Before we score those, it helps to be clear on what the molecule actually is and what the evidence supports.

What urolithin A does, briefly

Urolithin A is a gut postbiotic. Your microbiome converts ellagitannins from pomegranate, walnuts, and berries into urolithin A — but only some people convert it efficiently, which is the main reason a standardized supplement is useful at all. Its studied mechanism is mitophagy: the recycling of worn-out mitochondria so cells can maintain a fresher, better-functioning population of these energy-producing structures. For the full biology, see our urolithin A guide and our overview of mitochondrial health.

The evidence, by strength

Established human findings

The strongest human data is in muscle and mitochondrial function. Andreux et al. (2019, Nature Metabolism) was the first-in-human trial and found urolithin A safe and well tolerated up to 1,000 mg per day, with a mitochondrial gene-expression signature in older adults. Liu, D'Amico et al. (2022, JAMA Network Open) studied older adults for about four months and reported improved muscle endurance measured as contractions before fatigue. Singh et al. (2022, Cell Reports Medicine) tested 500 mg and 1,000 mg per day for four months in middle-aged adults and reported gains in muscle strength and exercise performance.

Newer human research

A 2024 randomized controlled trial in the Journal of the International Society of Sports Nutrition looked at endurance and recovery markers over eight weeks in resistance-trained men. A 2025 Nature Aging trial (about 28 days) reported support for immune-cell mitochondrial health in midlife adults, and a 2025 distance-runner trial added performance data. A 2024 systematic review in Ageing Research Reviews is candid that the human evidence is still emerging, with short trials and modest sample sizes — promising, not settled.

Preclinical research (animal and cell only — not human proof)

Ryu et al. (2016, Nature Medicine) is the foundational study: mitophagy, extended lifespan in C. elegans, and improved muscle function in rodents. D'Amico et al. (2022, Aging Cell) examined joint and cartilage mitochondrial health in osteoarthritis models. Skin, gut, brain, and heart applications remain at the early, preclinical stage — laboratory and animal work is exploring them, but they are not proven in people. Any brand, including Renue By Science, that leans on those areas is describing early research, not human outcomes.

The scorecard: how to judge Renue By Science

Dose

Human trials used roughly 500 to 1,000 mg per day, with 1,000 mg the top of the studied range. The single most important thing to check on Renue By Science's label is the urolithin A milligrams per serving — and whether that is one capsule or several. A product can be perfectly good at a lower dose, but you should know where it sits relative to the studied amounts before you compare prices. Our dosage guide shows how the trial doses map to daily servings.

Testing

Because urolithin A is a manufactured ingredient, third-party testing is the credibility check that matters most. Look for whether Renue By Science publishes or provides certificates of analysis confirming identity and purity. SOMA HEALTH is third-party tested; hold every brand, ours included, to that same standard.

Format

Renue By Science works within capsule and related delivery formats common to the longevity space. Format is a personal-fit question: capsules are compact and easy for people comfortable swallowing pills, while a gummy removes that barrier and can support the daily consistency these multi-month trials required. Neither changes the molecule. Our comparison of the best urolithin A gummies is useful if the chewable route appeals to you.

Value

Judge value by cost per gram of urolithin A per day, not the sticker price of the bottle. Take Renue By Science's current per-serving dose and price from their label, work out the daily cost at a dose that matches the studies, and compare on that basis. A large 'total milligrams per bottle' number can look impressive while the per-serving dose is modest, so always bring it back to the daily gram.

A note on health conditions

Urolithin A is a structure/function ingredient that supports mitochondrial and muscle health. It is not a treatment for any disease, and this review is educational, not medical advice. If you are pregnant or nursing, managing a condition affecting your muscles, joints, immune system, heart, or metabolism, or taking medication, urolithin A is not a treatment — see your doctor before starting. For tolerability, see urolithin A side effects.

Bottom line

Renue By Science is a legitimate longevity brand with a urolithin A option, and the right way to evaluate it is on the merits: confirm the per-serving dose against the 500–1,000 mg studied range, look for third-party testing, pick a format you will take daily, and compare cost per gram per day. Do the same to SOMA HEALTH — 1,000 mg per serving, third-party tested, $79 for a 30-day supply — and choose the product that fits your routine and budget. The molecule is the same; consistency and honest math decide the rest.
