What is Urolithin A?

Urolithin A is a postbiotic — a compound your gut bacteria produce when they break down ellagitannins found in pomegranate, walnuts and berries. It’s become one of the most studied natural ingredients in longevity science because of what it does inside your cells: it supports mitophagy, the body’s natural process for clearing out worn-out mitochondria so healthier, more efficient ones can take their place.

Here’s the catch with getting it from food: only a minority of adults host the specific gut bacteria needed to convert pomegranate or walnuts into meaningful amounts of Urolithin A — and even those who do would need impractically large quantities to reach a research-level dose. Supplementing directly removes that lottery, giving every user a consistent, standardised 500mg.

Why the dose matters

The 500mg serving isn’t a marketing number. It matches the dose used in the landmark randomised, placebo-controlled trial published in Cell Reports Medicine (2022), in which four months of daily urolithin A supplementation was associated with improvements in muscle strength and markers of mitochondrial health in middle-aged adults. We formulate to the evidence, not below it — so you get the full researched dose in every capsule, not a fractional amount designed to look good on a label.†

Urolithin A works from the inside out. Your cells feel the benefits before you do — here’s the timeline research points to:

Hours after your first dose — Absorption
Urolithin A is absorbed and levels rise in your bloodstream, reaching tissues like your muscles.

Day 2 — Recycling switches on
Urolithin A helps stimulate mitophagy — the cellular clean-up process that identifies and recycles tired, underperforming mitochondria.

Around Day 30 — Renewal
With the old cleared out, your cells can produce fresh, healthier mitochondria — the powerhouses that turn food into usable energy.

Around Day 60 — Efficiency
With mitochondria renewed and recharged, cells across the body can function more efficiently.

Day 120 and beyond — Strength & endurance
In clinical research, roughly four months of consistent use is where improvements in muscle strength and endurance measures showed up — which is why we recommend treating Urolithin A as a long-term foundation, not a quick fix.†

Welzo is a UK health and wellness company built on transparency. Our Ultra Purity range exists to give people premium, evidence-led supplements without paying for a celebrity-brand badge. We publish our dosing rationale, we don’t hide behind proprietary blends, and we test what we sell. When a compound has genuine human research behind it — as Urolithin A does — we formulate to match that research at a fair price. Real doses, real testing, no theatre. Every batch of Welzo Ultra Purity Urolithin A is manufactured in a facility operating to GMP standard and undergoes independent third-party laboratory analysis. Testing confirms identity and potency (that each capsule contains the stated 500mg of Urolithin A) and screens for heavy metals, microbial contaminants and other impurities to meet our Ultra Purity specification. A Certificate of Analysis is available on request. We believe purity should be provable, not assumed — if a brand won’t show you the numbers, you shouldn’t have to take their word for it.
