Summary

This study tested a probiotic supplement made from pasteurized Akkermansia bacteria in 61 overweight or obese adults. Participants took either the probiotic or a placebo for 12 weeks while following a low-carb diet. The goal was to see if the supplement helped with weight loss, body fat, and blood cholesterol levels.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Pasteurized Akkermansia muciniphila Akk11 (a killed probiotic bacteria)
What this could lead to
If it works, this could offer a new probiotic supplement to help with weight management and improve blood fat levels in overweight or obese adults.
What could go wrong
This is a small, completed trial with only 61 participants. The effects may be modest, and results might not apply to everyone. Probiotics can cause mild digestive upset.
