Gut bugs on board: probiotic drops may beat Traveler's tummy troubles
NCT ID NCT07163819
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tests whether taking probiotic drops before and during a short overseas trip (less than 7 days) can prevent stomach issues, sleep problems, and other travel-related health problems. 46 healthy adults will take either a mix of three Bifidobacterium strains or a placebo daily. Researchers will check gut bacteria, symptoms, and even antibiotic resistance genes to see if probiotics help keep travelers healthy.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Probiotic drops containing Bifidobacterium longum subsp. infantis M-63, B. breve M-16V, and B. longum BB536
What this could lead to
If it works, this could point toward a simple probiotic supplement to reduce traveler's diarrhea and other gut issues during short trips.
What could go wrong
This is a small Phase 2 trial with only 46 participants, so results may not apply to everyone. Probiotics may not work for all types of travel or gut problems.
