Youth & Earth vs SOMA HEALTH: Liposomal Capsule vs Gummy

Reviewed by SOMA HEALTH's Medical Research Team

Youth & Earth and SOMA HEALTH both sell urolithin A, but they take opposite bets on format: a 500 mg liposomal capsule versus a 1,000 mg sugar-free gummy. This is a straight comparison of dose, delivery format and day-to-day convenience so you can pick the one you will actually stick with.

The two products at a glance

Youth & Earth Liposomal Urolithin A is a capsule marketed at 500 mg with a liposomal delivery system positioned for enhanced absorption, sold in a 60-count bottle, and labeled vegan, gluten- and soy-free and non-GMO.

SOMA HEALTH Urolithin A Gummies deliver 1,000 mg of urolithin A per 4-gummy daily serving, in a sugar-free raspberry gummy, 120 gummies for a 30-day supply, third-party tested.

So the head-to-head is really three questions: how much urolithin A do you want per day, do you prefer a capsule or a gummy, and which format will you take consistently. Everything else follows from those. If you want the underlying science first, our complete urolithin A guide covers it in full.

Round 1: Dose

This is the most important axis, because urolithin A's effects in human trials are tied to specific amounts. Studies have generally used 500 mg and 1,000 mg per day.

Singh and colleagues, in Cell Reports Medicine (2022), tested both 500 mg and 1,000 mg arms in middle-aged adults over four months and reported effects on muscle strength and aspects of exercise performance - which is why both doses are defensible. The first-in-human study (Andreux and colleagues, Nature Metabolism, 2019) reported UA was safe and well tolerated up to 1,000 mg per day. A 2022 JAMA Network Open trial (Liu, D'Amico and colleagues) in older adults reported muscle endurance improvements over about four months, and a 2025 Nature Aging trial over roughly 28 days reported UA supported immune-cell mitochondrial health in midlife adults.

The takeaway: Youth & Earth sits at the lower studied dose (500 mg); SOMA HEALTH sits at the top of the range (1,000 mg). If your goal is to match the highest amount used in the human research in one simple daily serving, the gummy gets you there directly. If you prefer to start lower, 500 mg is well supported. Our dosage guide walks through how to choose.

Round 2: Absorption and delivery format

Youth & Earth's headline mechanism is liposomal delivery - the active wrapped in a lipid layer to aid absorption. It is a legitimate formulation strategy, and the theory is that better uptake lets a lower dose work harder. Two honest caveats matter here. First, the pivotal human urolithin A trials were run on defined oral doses of the compound, not on a specific brand's liposomal system, so "enhanced absorption" is a formulation rationale rather than a separately proven clinical result. Second, absorption is a reason to respect a dose, not a substitute for it. A verified 1,000 mg serving is a large, studied amount on its own terms.

SOMA HEALTH's bet is different: rather than optimize a smaller dose, deliver a full 1,000 mg in a format people enjoy taking, and verify it with third-party testing. Both are valid philosophies. The way to keep the comparison honest is to anchor on milligrams that are independently confirmed, then treat delivery format as a tie-breaker.

Round 3: Convenience and adherence

This is where the two formats genuinely diverge, and it may be the deciding factor. A capsule is compact and travel-friendly, which suits people who already take pills and want the smallest possible package. A gummy removes the pill-swallowing barrier entirely and tends to be easier to remember, because it feels like a treat rather than a chore - but only if it is sugar-free, which SOMA HEALTH's is, so a daily habit does not add sugar. The supplement that works is the one you take every day, so be honest with yourself about which format you will not skip.

Serving mechanics differ too. SOMA HEALTH's daily serving is four gummies to reach 1,000 mg, from a 120-gummy, 30-day bag. Youth & Earth's serving is capsule-based at 500 mg - check their label for exactly how many capsules make up a serving and how long a 60-count bottle lasts, since that drives your real cost per day.

What neither product can claim

Both brands are selling the same molecule, and the same honesty applies to both. Urolithin A is a gut postbiotic that supports mitophagy - the recycling of worn-out mitochondria - and the strongest human evidence is in muscle function and cellular or mitochondrial markers. The mechanism itself was established largely in preclinical work: Ryu and colleagues (Nature Medicine, 2016) showed mitophagy, lifespan effects in C. elegans and muscle benefits in rodents, and joint or cartilage effects (D'Amico and colleagues, Aging Cell, 2022) come from osteoarthritis models. Skin, gut, brain and heart benefits remain early and exploratory. The 2024 systematic review Targeting aging with urolithin A in humans (Ageing Research Reviews) concluded the human evidence is still emerging. You can read the trial summaries in our clinical studies overview.

Neither product is a treatment for aging or any disease. Urolithin A is a wellness supplement. If you have a health condition, take medication, or are pregnant or breastfeeding, talk to your doctor before starting, and see your doctor for any medical concern rather than relying on a supplement.

Bottom line

Choose Youth & Earth if you prefer capsules, want to start at the lower 500 mg studied dose, and value a liposomal format. Choose SOMA HEALTH if you want the top of the studied range at 1,000 mg, prefer a sugar-free gummy over pills, and want third-party testing on a full daily dose. Both are legitimate; the right pick is the format you will take consistently at a dose you are comfortable with - normalized on cost per verified milligram.
