Summary
This study tests whether a daily supplement called Cardiosyn can increase helpful gut bacteria in healthy adults who eat a typical Western diet. The supplement contains a natural sugar found in human milk along with probiotics. One hundred participants will take the powder for about 8 weeks, and researchers will measure changes in their gut bacteria and blood markers.

What this could lead to
