Roll Call does not check drug interactions or assess personal safety.
A short-chain carbohydrate made by heating and enzymatically treating cornstarch so that much of it passes through the small intestine undigested, functioning as a soluble dietary fiber.
Why it’s used
Used to add fiber to a food or supplement, and taken by some to support bowel regularity or to soften the rise in blood sugar after a carbohydrate-containing meal.
What the evidence says
Resistant maltodextrin behaves like other soluble fibers in small trials on stool bulk and post-meal glucose response, but the specific human evidence base for this ingredient is thin and inconsistent, and no major fact-sheet body has issued a settled verdict on it.
