What it is

Vitafiber is a brand name for a type of soluble corn fiber. It is a prebiotic fiber made from corn starch through an enzymatic process. This process breaks down the starch into shorter chains of glucose molecules that are more resistant to digestion.

Why it's used

Manufacturers add Vitafiber to foods as a source of dietary fiber and to provide a mild sweetness. It functions as a bulking agent and can help improve the texture of products. It is commonly found in snack bars, protein bars, baked goods, and some beverages.

Health notes

Vitafiber is generally recognized as safe (GRAS) by the FDA for use in food. As a prebiotic fiber, it can support gut health by feeding beneficial bacteria in the digestive system. Some individuals may experience gas or bloating when consuming large amounts of soluble fiber. JECFA has evaluated soluble corn fiber and did not set a numeric limit (ADI not specified).

Allergen info

Vitafiber is derived from corn, which is not one of the nine major allergens. It is also gluten-free.
