NCT ID NCT07705659
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This trial investigates whether a probiotic supplement containing two strains of Bifidobacterium longum can help maintain gut health and reduce symptoms like digestive issues, respiratory problems, and poor well-being during short overseas trips (7 days or less). Healthy adults traveling from China to an overseas destination take one sachet of the probiotic or a placebo daily from departure until return. The study measures changes in gut bacteria, immune markers, and self-reported symptoms.
