Dahlian fiber, derived from the dahlia tuber, is a rich source of inulin, a type of soluble dietary fiber. There is scientific evidence supporting its use for supporting the large intestine (colon) body system. Inulin acts as a prebiotic, meaning it serves as food for beneficial gut bacteria, such as Bifidobacteria and Lactobacilli. Several human and animal studies have demonstrated that inulin supplementation increases the populations of these beneficial microbes, which in turn improves gut health, promotes regularity, and can help alleviate constipation.

Moreover, fermentation of inulin by gut bacteria produces short-chain fatty acids (SCFAs), such as butyrate, acetate, and propionate. SCFAs play a vital role in maintaining colonic health by providing energy for colonocytes, reducing inflammation, and enhancing the integrity of the intestinal barrier. Clinical trials have shown that regular consumption of inulin-containing fibers like dahlian fiber can lead to softer stools, increased stool frequency, and improved overall bowel function, especially in individuals with mild constipation.

While most studies focus on inulin from chicory root, the chemical structure and physiological effects of dahlian inulin are comparable. Therefore, there is a robust scientific rationale for using dahlian fiber to support colon health, specifically through its prebiotic effects and its role in promoting bowel regularity and microbial balance.
