Isomalto-oligosaccharide (IMO) is a soluble fiber made from plant starches. It tastes sweet and supplies fewer calories than sugar. Food manufacturers add it to products, and you can take it as a supplement to support digestion and regularity. IMO syrup or powder blends easily into drinks, yogurt, or baked goods.
Inside your gut, IMO acts as a prebiotic, feeding the beneficial bacteria that live there. Introducing it too quickly can cause gas or bloating. Start with a small dose and increase slowly.
