What Is Traveler's Diarrhea?

Traveler's diarrhea is the most common travel-related illness, affecting between 5% and 50% of international travelers depending on destination. It is caused primarily by consuming food or water contaminated with bacteria, most commonly enterotoxigenic E. coli. Onset typically occurs within the first two weeks of travel. Symptoms include loose or watery stools, abdominal cramps, and nausea. High-risk regions include South and Southeast Asia, sub-Saharan Africa, and parts of Latin America.

Probiotics When Travelling: Gut Support

The digestive system faces multiple stressors during travel: diet changes, irregular schedules, jet lag, and exposure to unfamiliar bacteria. Probiotics are live microorganisms that, when consumed in adequate amounts, contribute to a healthy digestive flora. Published research on probiotics when travelling and traveler's diarrhea is mixed and strain-specific. Bio-K+'s three proprietary strains have been the subject of 16 published clinical trials.

Antibiotic-Associated Diarrhea and Travel

Travelers who take antibiotics face a secondary digestive risk: antibiotic-associated diarrhea (AAD). Antibiotics broadly disrupt gut microbiota, which can allow Clostridioides difficile to establish a foothold. Bio-K+ Antibio Pro is a Health Canada-approved NHP. It helps to reduce the risk of developing antibiotic-associated diarrhea (AAD). It also helps reduce the risk of developing C. difficile-associated diarrhea (CDAD) in hospitalized patients. These claims apply when a course of antibiotics is being taken.
