What to expect
A realistic timeline for
what you'll notice.
Urolithin B supports cellular health over weeks of consistent use. It is not a stimulant. Here is what customers report, and when. Individual results vary.
Days
1–7
Nothing dramatic — and that's expected
Urolithin B acts at a cellular level. Most customers report no noticeable change in the first week. This is normal — the compound works biochemically, not as a stimulant.
Weeks
2–4
Digestive comfort and gut tone
The most commonly reported early observations are improved digestive comfort and a sense of gut regularity. Urolithin B is a postbiotic — its primary site of action is the intestinal environment. Individual results vary.
Weeks
5–10
Sustained digestive comfort
By weeks 5–8, customers report digestive improvements feel more consistent rather than occasional. Results depend on diet, gut health baseline, and consistency of daily use.
Month
3+
Long-term cellular support
Urolithin B is designed for consistent long-term use. Its role in supporting normal cellular function is best assessed over months, not days. Cellular health is a long-term commitment.
The Formula
Built on published research
One molecule. Full-dose transparency. No proprietary blends.
300
mg Urolithin B per serving
Plant-derived postbiotic
Derived from pomegranate (Punica Granatum). Urolithin B is produced in the gut from ellagitannins — but conversion efficiency varies significantly between individuals. Direct supplementation bypasses that variability.
🌿
Postbiotic — not a probiotic
A distinct category
Urolithin B is a postbiotic: a biologically active metabolite produced by gut bacteria from plant polyphenols. Unlike probiotics (live bacteria) or prebiotics (fibre), postbiotics are stable, well-defined compounds. No refrigeration needed.
Early stage
Honest framing
Emerging research area
Urolithin B is a newer research area. Most published work is preclinical or early-phase. We are transparent about this: the evidence is promising, but human trial data is limited. This is a cellular support food supplement.
The science
What is Urolithin B?
Urolithin B is a naturally occurring compound produced when gut bacteria metabolise ellagitannins — polyphenols found in pomegranate, walnuts, and certain other plants. It belongs to a class of compounds called urolithins, classified as benzocoumarins. CAS number: 1139-83-9.
The key distinction between Urolithin B and Urolithin A lies in hydroxylation pattern. Urolithin A carries hydroxyl groups at positions 3 and 8. Urolithin B carries a hydroxyl group at position 3 only. Both are produced in the gut from the same dietary precursors, but individual conversion efficiency varies significantly — which is why direct supplementation bypasses that variability entirely.
Urolithin B is classified as a postbiotic — a biologically active metabolite produced by gut microbiota from plant polyphenols. Unlike probiotics or prebiotics, postbiotics are stable, well-defined compounds that require no refrigeration.
Compound class
Postbiotic · Urolithin · Benzocoumarin
Produced by gut microbiota from ellagitannins in pomegranate and other plant sources. CAS: 1139-83-9.
Dietary source
Pomegranate (Punica Granatum)
Also found in walnuts and raspberries. Conversion from dietary sources varies widely between individuals.
vs Urolithin A
Hydroxyl at position 3 only
Urolithin A (CAS 1143-70-0) has hydroxyl groups at positions 3 and 8. Urolithin B has position 3 only. Different compounds, different research profiles.
Research context: Urolithin B is a newer research area. Most published work is preclinical or early-phase. Human trial data is limited. Urolithin B is a cellular support food supplement, not a pharmaceutical. It does not treat any disease or medical condition.

Urolithin B
Urolithin B — a plant-derived postbiotic for cellular support
Urolithin B (CAS 1139-83-9) is a naturally occurring compound produced when gut bacteria metabolise ellagitannins found in pomegranate and certain nuts. Classified as a urolithin and a postbiotic. Not everyone converts ellagitannins efficiently — supplementing directly bypasses this conversion step entirely.
As a food supplement, Urolithin B contributes to digestive wellness and supports normal cellular function. Each serving provides 300mg from high-purity pomegranate extract in vegan HPMC capsules.
- Contributes to digestive comfort and wellness
- High-purity, plant-derived postbiotic from pomegranate
- Supports normal digestive function
- Single active ingredient — no unnecessary additions
- Vegan HPMC capsule · gluten-free · dairy-free · no artificial fillers

Common questions
Frequently asked
Urolithin A and Urolithin B are both postbiotic compounds produced when gut bacteria break down ellagitannins from pomegranate and other plants. They differ in hydroxylation pattern: Urolithin A has hydroxyl groups at positions 3 and 8; Urolithin B has a hydroxyl group at position 3 only. Urolithin A has a larger published human research base. Urolithin B research is at an earlier stage with most published work preclinical.
A postbiotic is a biologically active compound produced by gut microbiota from plant polyphenols. Unlike probiotics (live bacteria) or prebiotics (dietary fibre), postbiotics are stable, well-defined compounds requiring no refrigeration.
