What is Prebiotic Fiber?
Prebiotic fiber is a type of nondigestible carbohydrate that serves as a substrate for beneficial gut bacteria. It is commonly derived from plant sources such as inulin, fructooligosaccharides (FOS), and galactooligosaccharides (GOS). Prebiotic fibers are used in dietary supplements and functional foods, particularly in formulations marketed for gut health and immune system support. These fibers contribute to the overall fiber content of a product and are often included alongside probiotics or other digestive health ingredients. Their role is primarily to influence the gut microbiota environment rather than act as a direct nutrient.
