Supports healthy bowel regularity*

  • Prebiotic fiber that feeds beneficial bacteria
  • Benefits digestive and metabolic health
  • Safe for long term use and in the 2nd and 3rd trimester of pregnancy

Xylo-oligosaccharide (XOS) is a prebiotic fibre that promotes the growth of beneficial bacteria in the gut. Many different prebiotic fibres exist on the market, however XOS is different. All other prebiotics promote the growth of all bacteria in the gut: good and bad, but XOS selectively promotes the growth of only beneficial microflora, namely the Bifidobacterium strains. As the number of beneficial flora increases, they can inhibit the growth of harmful bacteria by competing with them for resources. These beneficial strains also lower the pH of the intestines to make it an inhospitable environment for harmful bacteria to live. Improved gut microflora has benefits for digestive, cardiovascular, and overall health, especially in improving occasional gastrointestinal disorders.
