Can a postbiotic soothe diarrhea in vulnerable kids?
NCT ID NCT07758933
First seen Aug 11, 2026 · Last updated Aug 12, 2026 · Updated 1 time
Summary
This trial is testing whether a postbiotic supplement called Lactobacillus LB (Lactéol®) is safe for hospitalized children under 18 with weakened immune systems who have diarrhea. Participants receive the supplement twice daily for 14 to 28 days alongside standard rehydration and nutrition. The main goal is to monitor for side effects like vomiting, bloating, or allergic reactions, while also exploring whether it helps stop diarrhea and improve stool consistency.
