Prebiotic Fibers
Prebiotic fibers such as inulin, fructooligosaccharides (FOS) and galactooligosaccharides (GOS) are substrates used by gut microorganisms.
Quick answer
Prebiotic fibers are fermentable fibers used by certain microorganisms in the gut. Common label examples include inulin, chicory root fiber, and acacia fiber.
What to know
Not every fiber is described as a prebiotic, and probiotics are different. Probiotics are live microorganisms. Prebiotics are substrates used by microorganisms. Some products contain both. Check the ingredient name, amount, serving size, and whether a product identifies a probiotic strain. A label with several gut-related terms still needs to be read as a full formula.
Source / Origin
Plant sources including chicory root, Jerusalem artichoke and legumes.
