Summary

This study tests whether a probiotic supplement containing Bifidobacterium longum can help overweight or obese children aged 3 to 14 improve their body mass index (BMI). Sixty children will receive either the probiotic or a placebo for 8 weeks, along with lifestyle advice. Researchers will also check changes in gut bacteria to see if probiotics affect the microbiome.

Bifidobacterium longum probiotics
What this could lead to
If it works, this could point toward a simple, safe supplement to help manage weight in children with obesity.
What could go wrong
