Fibredex®XOS
The low-dose prebiotic. Bifidogenic from 1.4 g a day, so a claim fits inside a gummy, a shot or a single serve.
What it is
Xylo-oligosaccharides are short chains of xylose, two to seven units long, cut from the xylan in corncobs. Bifidobacteria take to them faster than to almost any other fibre, which is why a gram or two does the work that other fibres need fifteen for.
Three steps from source to powder
Corncob, a by-product rich in xylan
Enzymes cut the xylan into short xylose chains, DP 2 to 7
Filtered and concentrated to 35% to 95% XOS grades, as powder or syrup
How it behaves in the pot
Six things a formulator asks before anything else. Five bars is a lot of that property, one bar is a little, and neither is good or bad on its own. It depends on the food.
Typical values for food grades. Every FIBREDEX® lot ships with its own COA and specification.
Fits best in
Handle with care
Not a bulking agent, and mildly sweet. Use it for the claim and let another family member carry the bulk. Keep daily doses near 10 g or below for comfort.
Where it works, and the evidence
The highlighted stops are where XOS is active along the gut. Below, the numbers behind the claims, with the study each one comes from.
Raised bifidobacteria over eight weeks with no gastrointestinal side effects
Finegold et al, 2014A stronger bifidogenic response at double the dose, still well tolerated
Finegold et al, 2014Retains structure through an hour at 100 °C across the whole pH range
Processing stability studyWhat you can say, where
Sugarcane XOS holds a GRAS no-questions letter at up to 2.4 g a day; label as a prebiotic, not as US dietary fibre
Permitted with use caps per category, for example 3.5 g per kg in yoghurt
Named in the prebiotic schedule of the Health Supplements and Nutraceuticals regulations
Regulatory summaries as of 2026. Confirm the live text and your category limits with the JJD regulatory desk before printing a label.
Pairs well with
No fibre in this family works alone for long. These are the pairings where XOS does its best work, and what the partner brings.
