Summary

This study tests whether a special probiotic (a type of good bacteria) can help healthy adults sleep better and feel less stressed during short trips. Researchers will give 60 volunteers either the probiotic or a placebo and track their sleep, stress, and gut health. The goal is to see if this supplement can make travel easier on the body and mind.
