Youth & Earth Liposomal Urolithin A Review: Worth It vs SOMA HEALTH?

Reviewed by SOMA HEALTH's Medical Research Team

Youth & Earth's Liposomal Urolithin A is a familiar name for people shopping this category, marketed on a 500 mg dose and a liposomal delivery system for enhanced absorption. This is a fair look at what that actually means, where the evidence is strong and where it is still emerging, and how it compares to a gummy format.

What Youth & Earth actually sells

The product is Youth & Earth Liposomal Urolithin A, sold as capsules in a 60-count bottle and marketed at 500 mg with a liposomal delivery format positioned for enhanced absorption. It is described as vegan, gluten- and soy-free and non-GMO. Those are reasonable, clean-label specifications. For the exact urolithin A amount per serving (that is, how many capsules make up a 500 mg dose) and for current pricing, check the current label, because serving size determines how long a bottle lasts and what your true cost per day is.

A quick note on why dose is the number that matters most: urolithin A (UA) is a gut postbiotic your body makes from ellagitannins in pomegranate, walnuts and berries - but only some people's microbiomes convert it efficiently, which is why a supplement with a defined dose exists in the first place. Once you are supplementing, the milligrams on the label are the thing to anchor on. We cover the science end to end in our complete urolithin A guide.

The dose question: 500 mg in context

Human trials of urolithin A have generally studied 500 mg and 1,000 mg per day. So a 500 mg product sits at the lower end of the studied range - which is a legitimate, evidence-backed dose, not an under-dose. It is worth being precise about what each amount has behind it.

What the human evidence shows

The first-in-human study, Andreux and colleagues in Nature Metabolism (2019), reported UA was safe and well tolerated at doses up to 1,000 mg per day and produced a mitochondrial gene-expression signature in muscle. Singh and colleagues, in Cell Reports Medicine (2022), directly compared 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 - useful because it tells us 500 mg is an active dose, while 1,000 mg is the top of the range. A 2022 randomized trial in JAMA Network Open (Liu, D'Amico and colleagues) in older adults over about four months reported improvements in muscle endurance measures. A 2025 Nature Aging trial over roughly 28 days reported UA supported the mitochondrial health of immune cells in midlife adults, and an 8-week 2024 trial in the Journal of the International Society of Sports Nutrition studied resistance-trained men.

Where it is still preclinical

UA's core mechanism is supporting mitophagy - your cells recycling worn-out mitochondria - demonstrated in foundational work by Ryu and colleagues in Nature Medicine (2016), which showed mitophagy, lifespan effects in C. elegans and muscle benefits in rodents. That is animal and cell data. Joint and cartilage effects (D'Amico and colleagues, Aging Cell, 2022) come from osteoarthritis models and are preclinical. Skin, gut, brain and heart benefits are the subject of early, exploratory research. The 2024 systematic review Targeting aging with urolithin A in humans (Ageing Research Reviews) concluded the human evidence is still emerging. Neither Youth & Earth nor SOMA HEALTH can honestly claim more than that, and any brand implying otherwise is overselling.

The liposomal absorption claim, examined fairly

Liposomal delivery wraps the active in a lipid layer, and the pitch is better absorption, which can in principle let a lower dose punch above its weight. This is a reasonable formulation strategy and it is not snake oil. Two honest caveats, though. First, the pivotal human urolithin A trials above were run on defined oral doses of the compound, not specifically on a given brand's liposomal system, so "enhanced absorption" is a formulation rationale rather than a separately proven clinical outcome for a specific product. Second, absorption enhancement is a reason to take a dose seriously, not a replacement for dose. The cleanest way to be confident you are getting a studied amount is to look at the milligrams and whether they are independently verified. We compare formats in depth in our roundup of the best urolithin A gummies.

Format: capsules vs gummies

Youth & Earth's product is a capsule. Capsules are compact, easy to travel with, and familiar. The trade-offs are also familiar: some people dislike swallowing pills, and it is easy to forget a capsule that lives in a bottle at the back of a cupboard. Gummies solve the swallowing and adherence problem for many people, at the cost of needing a well-designed sugar-free base to avoid adding sugar to a daily habit. Neither format is inherently superior - it comes down to which one you will actually take every day, which is the variable that determines whether any supplement does anything at all.

Who each product suits

Youth & Earth's 500 mg liposomal capsule is a sensible pick if you prefer capsules, want to start at the lower studied dose, and value a liposomal format. A gummy at 1,000 mg suits someone who wants the top of the researched range, dislikes pills, or knows they are more consistent with a gummy habit. If your priority is matching the highest studied amount in a single daily routine, a 1,000 mg product gets you there without stacking multiple capsules; if you prefer to ease in at 500 mg, the Youth & Earth dose is well within the evidence. Our dosage guide can help you decide which end of the range fits your goals.

One more practical point: whichever you choose, judge value on cost per verified milligram per day, not the sticker price. A 500 mg product and a 1,000 mg product are not the same serving, so normalize before you compare.

Finally, the honest framing both brands owe you: urolithin A is a wellness supplement, not a treatment for any disease, and it is not a treatment for aging. 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.
