Galactooligosaccharides (GOS)
Galactooligosaccharides (GOS) are prebiotic fibers feeding bifidobacteria—helpful when ramped slowly, but FODMAP-sensitive guts may need smaller steps.
Galactooligosaccharides (GOS) are prebiotic fibers that feed bifidobacteria—found in legumes, some dairy prebiotic products, and supplements. They may soften stool and support immune signaling when tolerated.
People sensitive to FODMAPs sometimes react to GOS until the gut adapts. Increase food sources or supplements slowly with water.
Common questions
-
Do GOS cause bloating like other FODMAPs?
They can—GOS is fermentable. Small servings spread across meals and a gradual ramp reduce gas while microbes adapt.
