Could a daily probiotic capsule ease constipation?
NCT ID NCT06969872
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a daily capsule of ABKefir probiotics can improve constipation symptoms like bowel movement frequency and stool consistency. Researchers will compare ABKefir to a placebo over 8 weeks in 165 adults aged 18–75 with functional constipation. The goal is to see if this supplement offers a simple, drug-free option for relief.
