This fiber comes from corn starch. An enzymatic process makes it resist digestion in the small intestine. It travels to the large intestine, where it ferments and acts as a prebiotic. Beneficial gut bacteria feed on it, which helps maintain bowel regularity. The powder dissolves easily into liquids or soft foods without changing their taste or texture.
Take 10 to 20 grams daily with meals. Start with a smaller amount and increase slowly over one to two weeks. This gives your digestive system time to adjust.
You might notice gas, bloating, or stomach upset when you first add this fiber to your diet. Build up the dose gradually to reduce these effects. This fiber can interfere with how your body absorbs some medications. Take any medication at least one hour before or two hours after consuming resistant maltodextrin. Do not use it if you have a rare hereditary galactose intolerance or glucose-galactose malabsorption.
