Inulin is a naturally occurring prebiotic dietary fiber (fructan polysaccharide) found in chicory root, Jerusalem artichoke, garlic, onions, and bananas. Commercial inulin is extracted primarily from chicory root. It resists digestion in the small intestine and is fermented by beneficial gut bacteria in the colon, promoting growth of Bifidobacterium and Lactobacillus species.
Adds fiber content to foods, acts as a fat replacer in dairy products, provides mild sweetness, and supports gut microbiome health as a prebiotic.
Generally safe and beneficial. At doses above 15–20 g/day, inulin commonly causes bloating, gas, abdominal cramping, and diarrhea due to rapid fermentation in the colon. This is well documented in peer-reviewed research. It is contraindicated for people with fructan intolerance or irritable bowel syndrome following a low-FODMAP diet. At normal food fortification levels (3–8 g/serving), it is tolerated by most adults.
