Inulin (Prebiotics)

A prebiotic fiber (usually from chicory root) that specifically feeds beneficial gut bacteria. Unlike sweeteners, it's not a sugar substitute but 'gut food' with genuine functional benefit.

Also known as: inulin, fos, fructooligosaccharide, fructooligosaccharides, präbiotika, prebiotics, zichorie, chicory

How it works

Inulin is a prebiotic fibre the human gut can't digest itself; instead it feeds beneficial gut bacteria. They ferment it into short-chain fatty acids such as butyrate, which nourish the gut lining and act anti-inflammatory. In larger amounts it can cause bloating.

Dosage

Ramp up slowly, 5–10 g/day. Too much at once → bloating.

Considerations

A well-supported prebiotic effect: inulin reliably promotes bifidobacteria and the production of butyrate — a fuel for the gut lining. Complements our [probiotics](/products/probiotika) (pre- + probiotics = a 'synbiotic'). Important: ramp up — in sensitive guts or IBS (FODMAP sensitivity) inulin can cause significant bloating. Yacon syrup is a natural, mildly sweet FOS source.
