Urolithin B (C13H8O3, MW 212.20, PubChem CID 5380406) is a gut-microbiota-derived ellagitannin metabolite that has moved from research curiosity to a recognised sports-nutrition ingredient candidate.
Why the interest
- Muscle-focused research: human myotube transcriptome work (PMID 42773997) has examined its effect on muscle-related gene expression.
- Small, stable molecule: a low molecular weight aglycone that is straightforward to standardise and blend.
- Positioning: complements creatine and protein in recovery and lean-mass formulas.
Main applications
- Sports nutrition: recovery, lean-mass and performance blends.
- Healthy-ageing formulas: mitochondrial and cellular-health positioning.
- Research and OEM: capsule, tablet and sachet development.
