How are we different?

For this product, we combine two special sugar polymers: XOS (xylooligosaccharides) and GOS (glucooligosaccharides), each characterised by specific molecular structures. We obtain the XOS powder from a renowned Japanese manufacturer, the "discoverer" of XOS. The XOS can be obtained from (non-GMO) corn via a patented production process. We obtain the GOS powder from a company with headquarters in France, which specialises in the processing and production of raw materials of plant and biotechnological (microbiological) origin. The GOS are obtained from sugar beets (sucrose and maltose) by enzymatic conversion.

No solvents such as N-hexane, methanol or acetone are used during either manufacturing process. To ensure the consistently high quality of the end products XOS and GOS, production is always closely monitored. The producers regularly and conscientiously conduct chemical analyses in order to always be able to guarantee the quality of the product.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC capsules that can be found on the market, are 100% free from controversial additives such as carrageenans and PEG. We use environmentally-friendly amber glass jars for the packaging of this product.

XOS (xylooligosaccharides) are polymers of xylose units with a C5 molecular structure. This means that the xylose molecules are made up of 5 carbon atoms in a ring and an aldehyde group (functional group). The xylose molecules are linked together by β-1,4 bonds.

GOS (glucooligosaccharides) are polymers of glucose units with a C6 molecular structure. This means that the glucose molecules are composed of 6 carbon atoms in a ring and an aldehyde group (functional group). The glucose molecules are linked together by α-1,2-glycosidic bonds.

XOS and GOS are classified as complex polysaccharides of dietary fibre. Both are very soluble in water. XOS and GOS cannot be broken down by human digestive enzymes. Some microorganisms such as bifido- and lacto-bacteria can use these sugar molecules as a natural food source.
