Summary

This completed study tested whether a probiotic called Akkermansia muciniphila Akk11 can help people with obesity lose weight. Over 12 weeks, 106 participants took either the probiotic or a placebo. Researchers measured changes in body mass index (BMI) and also looked at inflammation and metabolism. The goal is to see if this natural supplement could be a safe way to support weight management.
