Summary
This completed pilot trial tested two postbiotic supplements (ABB S3 and ABB C22) in 100 hospitalized patients with diarrhea or gut symptoms from tube feeding. The goal was to see if these nutritional supplements could ease symptoms like diarrhea, vomiting, and improve stool consistency. Researchers measured gut inflammation markers and symptom changes, but as a small early study, results are preliminary.
