Inulin is a natural, plant-based polysaccharide classified as a soluble dietary fiber and prebiotic. Extracted primarily from chicory root (Cichorium intybus), inulin plays a key role in supporting digestive health by promoting the growth of beneficial gut bacteria such as Bifidobacteria. Its non-digestible structure allows it to reach the colon intact, where it is fermented by the microbiota, producing short-chain fatty acids SCFAs) that benefit gut lining integrity, immune modulation, and metabolic health. Inulin is also recognized for its ability to improve calcium and magnesium absorption, regulate appetite, and support glycemic control. Available in powder form with various degrees of polymerization DP, inulin is highly versatile for use in capsules, sachets, functional foods, and beverages. It also offers excellent mouthfeel and fat-replacement properties, making it a valuable ingredient for product development in both dietary supplements and food applications.
