Fibredex®GOS
The prebiotic of infant formula, with immunity and calcium absorption evidence from infancy to older age.
What it is
Galacto-oligosaccharides are short chains of galactose on a glucose end, made from milk lactose by the same kind of enzyme the gut uses. They are the closest commercial relative of the oligosaccharides in human milk, which is why every major infant formula uses them.
Three steps from source to powder
Lactose from milk
Beta-galactosidase moves galactose units onto lactose, building chains of two to eight
Residual sugars reduced, then supplied as a syrup or spray-dried powder
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
Carries some residual lactose and browns with heat, so plan the process around it. Not for vegan positioning. Keep adult doses near 8 g a day or below.
Where it works, and the evidence
The highlighted stops are where GOS is active along the gut. Below, the numbers behind the claims, with the study each one comes from.
Raised bifidobacteria in healthy adults in a dose-response trial
Davis et al, 2010True calcium absorption in postmenopausal women at 20 g a day; fractional absorption also up in adolescents at 5 g
van den Heuvel, 2000; Purdue, 2013GOS with long-chain fructans brings bifidobacteria, stool pH and consistency closer to breastfed infants; 11 trials pooled in 2025
Knol et al, 2005; meta-analysis 2025What you can say, where
Galacto-oligosaccharides recognised since June 2018; GRAS in infant formula
Counts as fibre; GOS and FOS allowed in infant formula up to 0.8 g per 100 ml

Pairs well with
No fibre in this family works alone for long. These are the pairings where GOS does its best work, and what the partner brings.
Short-chain GOS feeds the near end of the colon, long-chain inulin reaches the far end. The most documented pairing in nutrition.
GOS for the prebiotic and immunity story, resistant dextrin for glycaemic support and process stability, in medical and elderly nutrition.
