When considering probiotics for travel, you typically want strains that can help with digestive health and immune support. While I can't recommend specific products, I can suggest looking for probiotics that contain the following strains, which are commonly beneficial:

1. Saccharomyces boulardii: Known for its ability to prevent and treat various types of diarrhea, including traveler's diarrhea¹.
2. Lactobacillus rhamnosus GG: This strain is well-researched for supporting gut health and boosting the immune system².

These probiotics are often taken before and during travel to help build resilience against unfamiliar bacteria that you might encounter.

If you would like to see a list of specific probiotic products, let me know, and I can find some options for you.
