Can a chicory fiber ease toddler constipation?
NCT ID NCT03941925
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This trial tests whether a prebiotic fiber from chicory, called fructans, can improve bowel habits in young children aged 1 to 3 with constipation. Half of the 100 participants will receive the prebiotic daily for four weeks, while the other half gets a placebo. Parents will track stool consistency, frequency, and amount in a daily diary to see if the fiber helps.
