Now Foods Inulin Prebiotic Pure Powder, 8 Oz

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.
