Longevity Box MitoSurge vs SOMA HEALTH: Which Urolithin A Wins?

Reviewed by SOMA HEALTH's Medical Research Team

MitoSurge from Longevity Box and SOMA HEALTH Urolithin A Gummies chase the same goal — supporting your mitochondria as you age — but they take almost opposite routes to get there. One is a fat-dependent powder capsule bundled with CoQ10; the other is a raspberry gummy dosed at the top of the clinical range. This guide compares them on the things that actually matter: dose, third-party testing, format, and how easily each one fits into a real daily routine.

A quick, honest disclosure before we start: SOMA HEALTH is a competitor of Longevity Box. We have tried to keep the numbers factual and the science conservative, and we cite only published human and preclinical research on urolithin A. Where we could not verify a current price or specification, we say so and point you to the label rather than guessing.

What each product actually is

MitoSurge is sold by Longevity Box, a UK-based supplement brand. Its label lists 250 mg of urolithin A per capsule, with a suggested serving of two capsules for 500 mg per day. A bottle holds 60 capsules, which the company frames as a one-month supply. Notably, MitoSurge is a multi-ingredient formula: alongside urolithin A, each daily serving adds CoQ10 (listed at 150 mg) and riboflavin/vitamin B2 (20 mg). Product reviews and the current listing indicate the formula shifted from an oil-filled softgel to a powder capsule, which the brand suggests taking with a fat-containing meal for absorption. Longevity Box states that batches are independently tested for purity. For the current price, promotions and any formula updates, check the live product page or label rather than an older number.

SOMA HEALTH Urolithin A Gummies deliver 1,000 mg of urolithin A in a four-gummy daily serving. A bag contains 120 gummies — a 30-day supply — in a sugar-free raspberry format, third-party tested, priced at $79. It is a single-ingredient approach: urolithin A only, no added CoQ10 or B-vitamins, so the dose is transparent and easy to track.

Dose: where each product sits in the studied range

This is the sharpest practical difference. Human trials of urolithin A have generally used 500 mg to 1,000 mg per day. MitoSurge at two capsules lands on the 500 mg floor of that range; SOMA HEALTH sits at the 1,000 mg ceiling.

Human evidence (the strongest tier). The first-in-human work, Andreux and colleagues in Nature Metabolism (2019), reported that urolithin A was safe and well tolerated at single doses up to 1,000 mg per day and produced a mitochondrial gene-expression signature in older adults. In a randomized trial of older adults published in JAMA Network Open (Liu, D'Amico and colleagues, 2022), roughly four months of supplementation supported measures of muscle endurance. Singh and colleagues, in Cell Reports Medicine (2022), studied middle-aged adults over four months using both 500 mg and 1,000 mg arms and reported support for muscle strength and aspects of exercise performance. Because that trial tested both doses head-to-head, it is the most relevant reference point for a 500-vs-1,000 mg comparison — both were studied; the higher dose is simply the upper end of what has been examined.

Newer human evidence. A 2025 randomized controlled trial in Nature Aging (roughly 28 days) reported support for immune-cell mitochondrial health in midlife adults, a line of work often described under the heading of inflammaging. A 2024 eight-week randomized trial in the Journal of the International Society of Sports Nutrition looked at resistance-trained men, and a 2025 trial in distance runners adds to the exercise-focused picture. These are promising but smaller and more specialized; they do not overturn the core findings, they extend them.

Preclinical research (label this clearly). The foundational mechanism paper, Ryu and colleagues in Nature Medicine (2016), demonstrated that urolithin A induced mitophagy, extended lifespan in the worm C. elegans, and improved muscle measures in rodents. Separately, D'Amico and colleagues in Aging Cell (2022) explored joint and cartilage outcomes in osteoarthritis models. These are animal and cell studies — encouraging for mechanism, but not human proof. A 2024 systematic review in Ageing Research Reviews summarized the human picture fairly: the evidence for targeting aging with urolithin A is still emerging.

How urolithin A works, in plain terms

Urolithin A is a gut postbiotic. Your body does not get it directly from food; instead, microbes in the gut convert ellagitannins — compounds in pomegranate, walnuts and certain berries — into urolithin A. Only some people carry the microbial mix needed to make meaningful amounts, which is a large part of why supplementing the finished compound is of interest at all. Once present, urolithin A is studied for its role in supporting mitophagy: the cellular housekeeping process that recycles worn-out mitochondria so that healthier ones can take their place. That single mechanism underlies most of the muscle, energy and cellular-health research above, and it is the same regardless of whether the delivery vehicle is a capsule or a gummy.

Format and daily-use ease

Here the two products diverge in everyday practicality. MitoSurge’s powder-capsule format is designed to be taken with fat for absorption, so timing it with a meal matters; the trade-off is that it also delivers CoQ10 and B2 in the same serving, which some people specifically want. If you already take a separate CoQ10, that overlap may be redundant rather than a bonus. SOMA HEALTH’s gummy format removes the pill-and-water step, tastes like raspberry, is sugar-free, and does not hinge on remembering to pair it with a fatty meal — you simply chew four gummies. For anyone who dislikes capsules or is managing several supplements, adherence tends to be the deciding factor, and a format you actually take every day is the one that has any chance of working. The four-gummy serving is worth noting: it is a slightly larger count than a two-capsule regimen, so people who prefer the fewest possible pieces per day should weigh that.

Testing and transparency

Both brands point to third-party or independent testing, which is the right expectation for a compound like urolithin A where label-accuracy investigations have found variability across the category. With any product, look for a current certificate of analysis and confirmation that the tested batch matches what you receive. SOMA HEALTH lists third-party testing and a single, transparent 1,000 mg dose; MitoSurge lists independent batch testing alongside its multi-ingredient blend. Neither claim substitutes for reading the current label.

So which one wins?

There is no universal winner — it depends on what you value. Choose MitoSurge if you specifically want a 500 mg urolithin A dose bundled with CoQ10 and B2 in one capsule and do not mind timing it with food. Choose SOMA HEALTH Urolithin A Gummies if you want the full 1,000 mg studied ceiling, a single transparent ingredient, and a format that is genuinely easy to stick with day after day.
