chicory inulin-type fructan

**Chicory inulin-type fructan** is a natural, plant-derived dietary fiber primarily extracted from the root of *Cichorium intybus* (chicory). It is made up of linear fructose polymers (fructans) linked mainly by β-(2→1) bonds, which are resistant to human digestive enzymes, resulting in prebiotic activity within the gut. Mechanistically, chicory inulin-type fructan acts as a soluble fiber that increases stool bulk, modulates gut microbiota—stimulating beneficial species like *Bifidobacterium* and *Lactobacillus*—and reduces constipation symptoms[1][2][3]. Human studies further associate its intake with improvements in bowel movement frequency and consistency, potential antihyperglycemic effects (notably lowering HbA1c), modulation of lipid metabolism (adiponectin increase), and modest reductions in body weight, BMI, fat mass, and waist circumference[2][3]. Clinical use is as a **dietary supplement** for digestive health, weight management, and metabolic support.
