The Active Ingredient Is: Xylooligosaccharides (XOS)

Xylooligosaccharides XOS are fermentable fibres that selectively support beneficial gut bacteria and help maintain normal digestive processes. This formula includes a branded prebiotic complex and is paired with galactooligosaccharides to enhance gut microbiota balance. XOS derives from plant-based sources to provide a natural fibre option.

What Does Xylooligosaccharides (XOS) Do?

XOS participates in sustaining healthy gut bacteria, aiding in the growth of Bifidobacteria and contributing to regular digestion. Dr. Finegold of University of California found that XOS increases Bifidobacteria populations, supporting gut function. NHS and EFSA acknowledge prebiotics can support digestion and gut health through these mechanisms.
