The Active Ingredient Is: Xylooligosaccharides (XOS)

Xylooligosaccharides, or XOS, are fermentable fibres that serve as prebiotics to feed the gut microbiome. This blend zeroes in on a targeted prebiotic fibre complex to back gut health and digestion.

This form includes XOS alongside Alpha-Glucooligosaccharides, creating a prebiotic blend intended to reach the colon and fuel beneficial bacteria.

What Does Xylooligosaccharides Do?

XOS helps to support the growth of good bacteria in the gut and participates in producing short-chain fatty acids, which play a part in gut barrier function and nutrient absorption. It may contribute to a balanced gut microbiome and normal digestion function.

Dr. Smith from University of Leeds found that prebiotic fibres can influence gut microbiota balance, aligning with observations of selective nourishment for beneficial bacteria.
