Probiotics for travel can be a game-changer to your travel plans. No one wants to get sick when they travel especially with an upset stomach…or worse loose stools! All those travel plans and excitement completely derailed.
In my experience, travel probiotics have made all the difference between good gut health and an incident-free vacation or one spent missing out stuck in your hotel room bathroom. Not only can probiotics help your digestive system, but they can also help prevent and stop traveler’s diarrhea and boost your immune system overall. Win-Win!
In this guide, Iāll share why I take probiotics to stay healthy and how to choose the best probiotics for travel.
Why I Take Probiotics for Travel
As a teacher, my immune system is constantly under attack from I don’t want to even know how many types of bad bacteria and viruses. From the normal everyday germs kids carry to sicknesses that take out an entire classroom a few children at a time, thereās almost nothing my immune system hasnāt battled.
But that still doesnāt mean I leave anything to chance when I travel. And neither should you. Thatās where probiotics come in.
I imagine you planned that trip to Cambodia to marvel at the Angkor Temples and Mexico to enjoy the fun in the sun not to learn pharmacy locations and stay hold up in a hotel bathroom. Visiting South America to explore Ecuador and finally see the Galapagos Islands is best done with a healthy gut. Am I right?
So, letās start with a few reminders of all the potentially harmful bacteria you might run into while traveling, as well as the parts of the travel experience that could make you sick or cause digestive issues.
1. Airports

From the automated touchscreen check-in kiosks to the public restrooms, security lines, unventilated airport terminals, and everything in between, airports are a germ’s fantasy come true with an unlimited number of people to whisk them on neverending round-the-world getaways.
Frequent traveler or not, weāve all cringed in restrooms with no soap to wash our hands or when seated close to someone who canāt stop coughing. Even before arriving at our destination, our immune function is being put to the test.
2. Your Body Clock

At home, most of us are creatures of habit. Our bodies are used to the rhythm of a typical day. The times you eat and sleep are consistent and your body manages its defenses in line with this internal clock.
Travel disrupts all of this. You change time zones, sleep at odd hours or maybe not at all, and eat different foods outside of your normal meal times. Even for healthy adults, these sudden changes to our body clock put a strain on the way the body works.
Not surprisingly gastrointestinal health is the easiest to knock off kilter. And this doesn’t even take into consideration any possible pre-travel anxiety you may have that also can affect an otherwise healthy gut.
3. Dehydration

Itās no secret flying dries you out. But did you realize lower levels of hydration can lead to fatigue? Not to mention, dryness means your body is less able to catch would-be germs and viruses before they have a chance to overwhelm your bodyās defenses.
Nasal passages are a first line of defense against bacteria and other germs. When they’re hydrated, they can flush out germs before they enter your system. This is a fancy way of saying, you feel the need to blow your nose or sneeze which gets rid of any intruders. But a dry nose has a harder time getting rid of germs.
Similarly, when you stay hydrated, the flow of water keeps things moving throughout your body.
4. Unsafe Water

Itās a sad fact most of the world doesnāt have access to clean drinking water from the tap. Drinking bottled water is the first step to protecting yourself.
But, what about raw fruits and vegetables? What water was used to wash them? Drinks served with ice become risky. Even brushing your teeth with tap water or accidentally opening your mouth in the shower can and will make you sick.
Most of us take clean water for granted and itās easy to accidentally turn the tap on your toothbrush or eat a salad without realizing it until itās too late.
I’ve personally seen a travel companion become so ill from food poisoning in Morocco after eating a salad that he ended up needing IV fluids and medication at a local hospital.
Bottom line: Water contamination is one of the easiest (and quickest) ways to increase your risk of traveler intestinal tract problems.
5. Everythingās Unfamiliar

Your body develops defenses against familiar germs at home. But, the germs from the New York City subway or at the Grand Palace in Bangkok are likely to be new. Your immune system will have to figure out how to defend against them in this new environment.
New destinations and experiences can be fun but also stressful. All of which can affect your ability to fight off a bug.
The same can be said for food. Unfamiliar foods and spices can upset your stomach even when they’re prepared and cooked in a safe, hygienic way. Add to that the possibility of your food being handled by someone who didn’t wash their hands or not being cooked and stored at higher temperatures to kill bacteria. It’s a recipe to upset your gut flora.
Why Probiotics?

You might be wondering why probiotics for travel. What about a multivitamin, extra Vitamin C, Zinc, or echinacea? Arenāt they what will really give your immune system a boost?
Iām certainly not taking anything away from these vitamins and herbs. Theyāve all factored into my staying healthy in the classroom at one time or another.
Now, Iām not a doctor and Iāve never taught science beyond 3rd grade but I can give you the elementary explanation of why probiotics can help you fight off all kinds of bugs.
The majority of your immune cells are in your gastrointestinal system. Probiotics contain āfriendlyā bacteria that can compete against āunfriendlyā bacteria.
According to the National Institute of Health’s scientific research, probiotics contain good bacteria that can make your bodyās shield against germs tougher and kick your immune cells into a higher gear when theyāre working to protect you against invaders.
This can not only help you from getting sick in the first place, but it can also help your gut microbiome get back on track faster after coming into contact with contaminated water or foods.
Best Probiotics for Travel

So, now that Iāve shared why I include probiotics as part of my daily life and travel routine, you might be asking which probiotics are best for travel.
If youāve ever shopped for probiotics (or any vitamin or supplement), youāve certainly seen how many brands there are with claims like, āthe best probiotic for menā or āprobiotics for constipation.ā
There are many different types of probiotics and I know how easy it is to feel overwhelmed and unsure about which probiotics are best. To be upfront and really clear, I have NOT tried all of the so-called best probiotic supplements. I found the right probiotics for me and I’ve continued to take them. (Why fix what isn’t broken, right?)
I use this ultimate probiotic formula because it makes sense for both my everyday life and for travel. These probiotics make good packing sense and give me enough protection no matter what germs I come across.

Probiotics for Travel: What to Look For
Whether you give the probiotics I take a try or choose from one of the many other quality probiotics, here are a few important things to look for.
First and foremost, you need shelf-stable probiotics that can be stored at room temperature. If a probiotic needs to be refrigerated, itās certainly not travel-friendly.
I know these are live probiotics because thereās a best-by date on the bottle. Thereās not much sense in taking or bringing along probiotics without live cultures for at least how long your trip is. Beneficial bacteria wonāt do much if itās not alive to fight off bad bacteria.
Look for probiotic labels that clearly show the CFU count. CFU stands for colony-forming units. Look for probiotics with a CFU in the billions and at least 30 billion for travel.
Look for probiotics that contain types of Lactobacillus, Bifidobacterium, and an overall diverse combination of bacteria. Lots of different strains of bacteria have been shown to be more powerful than probiotics with a single type of bacteria.
I take my probiotics regularly. But, if youāre looking to protect yourself just for an upcoming trip, plan to start up to a month before you leave for your trip, while youāre away, and for at least a week after your trip.
Iāve only ever taken the recommended dosage on the bottle and have found that to be fine for me. But it’s a good idea to talk to your doctor about the right dosage for you and the type of trip youāll be taking. Not all destinations have the same level of risk when it comes to travel illnesses.
Probiotics for Travel Bottom Line
Youāve put your time and energy into planning that long-awaited vacation. Flights and hotels have been paid for and personal time off days approved. By taking travel probiotics, youāre adding a layer of protection so you can enjoy your travels.
So whether you’re trying new foods, coming into contact with a lot of other people on public transportation, or feeling some travel anxiety, there’s no reason your digestive health (and your trip) has to suffer!

Thanks for this. On the subject of BA points I am leaving Paris today having used my points for 4 hotel nights. and a river cruise.
Great to hear that you got value from those Avios. Hope you’re trip to Paris was all you hoped for! š
After my last trip to South America in 2013 left me trapped in a bathroom for days and actually made me fly home early I wanted to try anything possible to keep my immune system up for my Nepal trip in 2017. I took probiotics for a month before I left and out of three weeks in Nepal only had a mild upset stomach for about 24-48 hrs halfway through. I know itās anecdotal but after that trip Iām convinced they helped! I was in remote areas without even running water and was fine. Iām headed back to South America again in a couple weeks and have pushed all my travel companions to take probiotics. Nothing ruins a trip worse than getting sick, do everything you can do avoid it and take your probiotics!!
Thanks for reading and for sharing your experiences, Heather. I’m so with you. I know they’ve helped me after learning my lesson in Cambodia. Have a great trip to South America!
Hi, Iām traveling to Thailand soon (on March 2nd, very close), and I was just told the other day about taking Probiotics. Not that my trip is only a week away, does it make sense to start the process today?
Thanks for reading, Alex. I’m not a doctor so can’t say for sure, but it can’t hurt. Have a great trip to Thailand! š
I have not taken them prior to travel, but on two successive trips to Mexico I became very ill; the second trip I contracted e coli and wound up in the hospital. They used a variety of antibitiocs and probtiotics to kill the infection and then protect my stomaceh. I plan on taking probioticis before my next trip
Oh no, Jeff! I’m sorry to hear that! I hope the probiotics beforehand help for your next trip. Thanks for reading. š
I usually start Florajen Probiotics for traveling about 2 weeks at least before I leave. I feel like that’s a solid amount of time for it to actually get in your system so you can feel the benefits. This article was amazing btw! Super helpful and informative! I didn’t even know about taking probiotics when traveling and thought it was more for when you’re on antibiotics until my cousin told me about all the health benefits especially with me traveling so much.
Thanks for reading, Olivia. Glad the article was helpful. š
Thank you so much for this helpful article! Iām traveling to the Dominican in 6weeks and wanted to start taking probiotics soon. I was wondering if you have a favorite brand that you like to take?
Thanks for reading, Amanda. I use the Swanson brand I link to in the article. š
Hey, thanks for the helpful article! I am taking a few supplements with me, including the probiotics which is in powder form. In you experience is it better to take probiotics in hand luggage or check in luggage?
Thanks for reading, Kyra. I always prefer in my checked luggage. Just be sure the probiotics are in their original bottle with clear labeling.
Hi, thank you for this post! The links to the probiotics is broken, can you please update and share the brand. We are leaving for Costa Rica in 4 weeks so want to start preparing!
Thanks so much for reading, Cheryl. And thank you for alerting me to the broken links! I’ve updated the post. All links work and lead straight to the probiotic I use. I hope you have a fabulous trip to Costa Rica! It’s fantastic there! š
