Isomalto-oligosacchride

Isomalto-oligosaccharide (IMO) is a type of carbohydrate made up of short chains of glucose molecules. It is often produced from starch, typically from corn or tapioca, through enzymatic processes. It functions as a prebiotic fiber.

Manufacturers add IMO primarily as a sweetener and a source of dietary fiber. It is often used in "sugar-free" or "low-sugar" products because it is less sweet than sucrose and has fewer calories. You can find it in snack bars, protein bars, and baked goods.

Isomalto-oligosaccharide is generally recognized as safe (GRAS) by the FDA for use in food. It is considered a prebiotic fiber, which may support gut health. JECFA has evaluated IMO and established an acceptable daily intake. Some studies suggest it can help regulate blood sugar and cholesterol levels, but more research is needed to confirm these effects at typical consumption levels.
