Inulin, a fructooligosaccharide (FOS), is a soluble prebiotic fiber that is resistant to digestion and reaches the large intestine essentially intact.* Intestinal probiotic bacteria consume inulin and in turn, produce the short-chain fatty acids that nourish the cells lining the colon.* Inulin thus helps to maintain intestinal health and function.* Inulin has a pleasant flavor that adds a mild sweetness to foods and drinks, but has a very low glycemic index and will not negatively impact serum glucose levels.
