Prebiotic fiber that feeds good gut bacteria and improves digestive health.
A soluble prebiotic fiber composed of fructose units that resists human digestion but serves as substrate for beneficial gut bacteria fermentation.
Inulin is a fructose polymer with 2-60+ fructose units linked together, naturally present in chicory root, Jerusalem artichokes, onions, garlic, and bananas. Because humans lack the enzymes to cleave inulin's bonds, it passes to the colon undigested where colonic bacteria selectively ferment it, preferentially feeding beneficial Bifidobacteria and Lactobacillus species. This fermentation produces short-chain fatty acids (butyrate, propionate, acetate) that support intestinal health, enhance mineral absorption, and provide metabolic benefits. Inulin has emerged as a popular prebiotic supplement, though high doses can cause digestive discomfort initially.
Functions as a prebiotic to selectively promote beneficial gut microbiota growth and produce short-chain fatty acids supporting metabolic and intestinal health.
Obtain inulin from whole food sources like onions, garlic, and chicory. If supplementing, start with small amounts (3-5g daily) and gradually increase to 15-20g daily to minimize digestive adaptation symptoms. Ensure adequate hydration to support fermentation and prevent discomfort.
