Fiber blends, often containing both soluble and insoluble fibers (e.g., psyllium, inulin, oat fiber), have been investigated for their effects in Crohn's Disease (CD), a form of inflammatory bowel disease. The rationale for using fiber is based on the role of dietary fiber in modulating the gut microbiota, enhancing production of short-chain fatty acids (SCFAs) like butyrate, and supporting intestinal barrier function. Some studies suggest that specific fibers, such as psyllium, may help prolong remission and reduce symptoms in CD patients, particularly in those with mild to moderate disease or in remission. However, evidence is mixed and often limited by small sample sizes, varying fiber types, and differences in disease activity or location.

Systematic reviews and clinical guidelines acknowledge that while fiber may benefit some CD patients—especially those without strictures or active disease—there is insufficient high-quality evidence to universally recommend fiber supplementation as a primary therapy. Moreover, fiber may exacerbate symptoms in patients with stricturing disease or during acute flares. The use of proprietary fiber blends has not been rigorously studied, and most available data pertain to individual fibers rather than blends. Therefore, while there is a plausible mechanism and some supporting research, clinical use should be individualized, and the overall level of evidence supporting fiber blends for treating Crohn's Disease remains modest.
