Testing a prebiotic capsule's effect on gut bacteria in healthy adults
This study tests whether taking a special capsule with prebiotics (a type of fiber that feeds good gut bacteria) changes the gut microbiome in healthy people without digestive conditions. You'll take the capsule for a short time and provide samples to measure changes.
