Inulin is a type of soluble dietary fiber found naturally in many plants, including chicory root, onions, and garlic. The primary rationale for using inulin to support or treat constipation, including in children, is based on its well-established prebiotic effects and its ability to increase stool bulk and improve bowel movement frequency. Several clinical studies have evaluated the effects of inulin supplementation on bowel function in both adults and children. For example, randomized controlled trials have demonstrated that inulin supplementation can increase stool frequency and soften stool consistency in constipated individuals, including pediatric populations. The mechanism involves fermentation of inulin by gut microbiota, resulting in greater production of short-chain fatty acids and increased water content in the colon, which helps to facilitate easier passage of stool.

A 2014 review in the World Journal of Gastroenterology and a 2019 systematic review in Nutrition Reviews both concluded that inulin and other prebiotic fibers can be effective in improving stool frequency and consistency in children with constipation, though the magnitude of effect may be modest. The evidence, while promising, is not uniformly strong across all studies due to differences in study design, dosage, and individual variability. Nonetheless, inulin is generally recognized as safe for children and is often included as a component in pediatric fiber supplements. Thus, scientific support exists, particularly for mild to moderate cases, but further high-quality research is warranted to refine recommendations regarding its optimal use in pediatric constipation.
