Inulin is a type of soluble dietary fiber classified as a fructan, commonly extracted from chicory root and other plants. It functions as a prebiotic, meaning it feeds the beneficial bacteria in the gut. In the context of sports and general wellness, inulin contributes to digestive health, nutrient absorption, and may assist with appetite control.
By supporting a healthy gut microbiome, inulin may indirectly improve immune function, energy metabolism, and even mood—all relevant to athletes and active individuals. It also plays a role in maintaining stable blood sugar levels, which can help sustain energy during prolonged activities.
Synonyms:
Fructooligosaccharide (FOS), Chicory root fiber
