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.

What this could lead to
If it works, this could offer a natural, daily supplement to ease constipation symptoms without medication.
