Summary

This early-stage study looks at how a single dose of a probiotic supplement changes gene activity and sugar patterns in the small intestine of 8 healthy adults. Participants will take the probiotic alone, with fiber, or a placebo, then have a small tissue sample taken the next morning. The goal is to understand how the probiotic works and whether simpler stool samples can replace gut biopsies in future studies.
