Urolithin A Supplements

What urolithin A is and where Pomella fits

Urolithin A is a postbiotic metabolite the gut microbiome produces from ellagitannins and ellagic acid, the polyphenols concentrated in pomegranate. Not everyone converts these precursors efficiently, which is why standardized pomegranate extracts are a practical way to deliver the raw material at a consistent dose.

The Pomella Powder and Pomella Capsules in this collection use a natural pomegranate extract standardized to punicalagins, the ellagitannin fraction the body uses to generate urolithin A. This is a food-derived, bioactives-first approach rather than a marker-only extract.

Urolithin A powder vs capsules

Powder gives you full control over dosing and blends easily into smoothies, yogurt, or water, which suits anyone who adjusts serving sizes or buys in larger quantities. It is also the format most people search for when they look for urolithin A powder or bulk pomegranate extract.

Capsules trade that flexibility for convenience and a fixed, pre-measured serving that travels well. Both formats use the same standardized Pomella extract, so the decision comes down to routine and preference rather than potency. Pair either with our broader anti-oxidative stress supplements for a wider polyphenol profile.

How to choose a quality urolithin A supplement

Start with what the extract is actually standardized to. A pomegranate extract should specify its punicalagin and ellagitannin content, not just a generic percentage of vague polyphenols, because those are the compounds that feed urolithin A production. Standardization is where an extract earns its label.

From there, the receipts matter. Every batch of Pomella here is third-party tested at ISO-accredited labs with a Certificate of Analysis published on the product page, and it is produced in cGMP, FDA-registered US facilities. That combination, real standardization verified by accessible testing, is the practical checklist for any supplement. You can read more about our approach on the Why ND page.

Urolithin A for cellular health and longevity

Research on urolithin A centers on mitophagy, the cellular housekeeping process that recycles worn mitochondria, which is why it draws interest for healthy aging and cellular renewal. Pomegranate polyphenols also contribute broad antioxidant activity that supports healthy cells throughout the body.

These use cases pair well with a wider longevity routine. Many people stack pomegranate extract alongside NMN, NAD supplements, and ubiquinol as part of a broader vitality approach.

How to use urolithin A precursor extract

Take Pomella with a meal to support absorption of its fat-friendly polyphenols and to keep it gentle on the stomach. A single daily serving is a reasonable starting point, and the powder makes it simple to scale that serving up or down within label guidance.

Consistency over time is what matters most with polyphenol supplements, since the gut microbiome does the work of converting precursors. Browse the rest of our nutritional supplements to round out a daily foundation.
