Inulin is a soluble fiber from chicory root, artichokes, and onions. It ferments in the gut, feeding beneficial bacteria. This fermentation supports regular bowel movements and overall gut health. The fiber softens stools, which may relieve occasional constipation.
Inulin comes as a powder that stirs into water, smoothies, or food. Because it is fermentable, start with a small dose and increase slowly to reduce gas or bloating. People with diabetes should watch their blood sugar, as inulin might affect it.
