Inulin

Inulin is a type of soluble dietary fiber and a naturally occurring polysaccharide belonging to a class of carbohydrates known as fructans. Naturally abundant in over 36,000 species of plants—including chicory root, Jerusalem artichokes, garlic, onions, leeks, and agave—inulin acts as an energy reserve for these plants. In human nutrition, it is widely recognized and utilized as a prebiotic. Because it resists digestion in the upper gastrointestinal tract, it reaches the colon intact, where it selectively feeds and promotes the growth of beneficial gut bacteria. It is available both as a functional food ingredient and as a standalone dietary supplement, often used to improve gut health, enhance metabolic function, and support weight management.
