Travel can upset your gut, but probiotics can help. Digestive issues like Traveler's Diarrhea affect 10–70% of travelers annually. Probiotics restore gut balance, boost immunity, and reduce the risk of digestive troubles caused by new foods, water, and stress. Here's a quick guide to age-based probiotic dosages to keep your gut healthy while traveling:
- Children (1–12 years): 2–10 billion CFUs daily. For antibiotic use, increase to 5–40 billion CFUs.
- Adults (18–64 years): 10–20 billion CFUs daily; increase to 20–40 billion CFUs during travel.
- Seniors (65+ years): 15–25 billion CFUs daily. Consult a doctor for specific needs.
When to start: Begin probiotics one week before travel, continue daily during the trip, and for at least one week after returning.
Best strains for travel:
- Saccharomyces boulardii (reduces diarrhea risk by 51%)
- Lactobacillus rhamnosus GG (prevents digestive issues)
- Bifidobacterium lactis (helps with constipation)
For convenience, choose shelf-stable probiotics that don’t require refrigeration, and stick to a daily routine for the best results. Keep your gut healthy and enjoy your trip!

How Travel Affects Your Gut Microbiome
Your gut microbiome plays a key role in keeping your digestion on track, but traveling often throws this delicate system into chaos.
Diet changes are one of the biggest culprits. When you’re traveling, your usual eating habits take a backseat to hotel buffets, street food, and restaurant meals. These unfamiliar foods can introduce ingredients your gut isn’t used to, potentially encouraging the growth of harmful bacteria.
Exposure to new bacteria is another hurdle. Traveling means encountering microbes your gut has never met before, which can disrupt its balance. For example, a study in Jimma, Ethiopia, found that 40% of local food handlers were infected with parasites or Salmonella. Dr. Larry Kosinski offers a simple rule to minimize risk:
"If you can't peel it or you can't cook it, you can't eat it".
Water quality differences also affect your gut. The source and cleanliness of water can influence your gut’s bacterial diversity. For instance, people who drink well water often have a broader range of gut bacteria compared to those who don’t. This, combined with other travel stressors, can make maintaining gut health even harder.
Jet lag and stress only add fuel to the fire. Changing time zones disrupts your body’s internal clock, which can weaken your gut’s barrier function and reduce microbial diversity. Dr. Cuckoo Choudhary explains how stress impacts overall well-being:
"Stress is a state of worry or mental tension caused by a difficult situation... the way we respond to stress makes a big difference on our overall, what we refer to as the wellbeing".
Stress doesn’t just affect your mood - it can slow down digestion, increase intestinal permeability (sometimes called "leaky gut"), and throw off your gut’s microbial balance. One study showed that university students experienced a rise in harmful gut bacteria as their semester stress levels increased. These combined stressors often lead to common gut troubles while traveling.
Common Gut Health Problems During Travel
When your gut microbiome is out of sync, it’s no surprise that digestive problems follow. One of the most common issues is Traveler's diarrhea, which affects anywhere from 10% to 70% of travelers. This condition not only disrupts digestion but can also introduce multidrug-resistant organisms into your system.
Other frequent complaints include bloating and gas, which happen when your gut bacteria struggle to process unfamiliar foods. Indigestion and upset stomach are also common as your microbiome works overtime to adjust to new eating schedules, foods, and the stress of travel.
Alarmingly, a study found that 53% of travelers returned home with at least one antimicrobial resistance gene acquired during their trips.
How Probiotics Prevent Gut Imbalance
Probiotics can be your gut’s best friend when traveling. These beneficial bacteria help restore balance, reduce inflammation, and strengthen your immune system. By starting probiotics before your trip and continuing them throughout, you can boost your gut’s natural defenses and crowd out harmful microbes from contaminated food or water.
Keeping your immune system strong is crucial when you’re exposed to unfamiliar germs. A healthy gut supports your immune system, and probiotics help maintain that balance. Research shows that travelers with stable gut microbiota often have higher levels of probiotic bacteria like Bifidobacterium, Lactobacillus, and Faecalibacterium before they even leave home.
Probiotics also help your gut adjust to new environments by calming inflammation caused by unfamiliar bacteria or food. Starting a probiotic regimen at least a week before your trip gives your gut time to build up beneficial bacteria, and continuing it during your travels keeps the protection going.
Scientists have even referred to the gut microbiome as the body’s "interface with the external world of the traveler". Protecting this vital system is key to enjoying your adventures without digestive distress.
Probiotic Dosage by Age Group
Finding the right probiotic dosage for your age is key to maintaining gut health, especially when you're on the move. Below are tailored dosage recommendations for different age groups to help keep your digestive system in balance while traveling.
Children (1-12 Years)
For kids, smaller doses are generally sufficient. A daily intake of 2–10 billion CFUs supports both digestion and immune health, which can be especially useful when encountering unfamiliar foods or bacteria.
Children are particularly susceptible to antibiotic-associated diarrhea (AAD). If antibiotics are prescribed, strains like L. rhamnosus GG ATCC53103 and S. boulardii CNCM I-745 have shown effectiveness in preventing AAD when taken at doses of 5 to 40 billion CFUs per day.
For convenience, probiotics for children often come in powder form, which can be easily mixed into drinks, yogurt, or applesauce. For instance, Optibac Probiotics Babies & Children is commonly recommended as one sachet daily, with the option to increase to two sachets under a healthcare provider's guidance.
However, probiotics aren't suitable for every child. They are generally not recommended for premature infants or children who are immunocompromised or critically ill. Always consult your pediatrician to determine whether probiotics are appropriate and to identify the best strains for your child.
Adults (18-64 Years)
For adults, a daily intake of 10–20 billion CFUs is typically recommended for general gut health. During travel, this dosage can be increased to 20–40 billion CFUs to help prevent digestive issues.
The International Scientific Association of Probiotics and Prebiotics (ISAPP) recommends at least one billion CFUs daily as the minimum effective dose, although higher amounts may provide additional benefits. Dr. Gina Jaeger, PhD, and Lead Research Writer for Nordic Naturals, emphasizes:
"The right dose of probiotics will depend on several factors - most notably, an individual's purpose for taking probiotics."
When antibiotics are part of your travel routine, the same strains effective for children - L. rhamnosus GG and S. boulardii - can also benefit adults, provided they are taken at the correct doses.
Adults can choose from various forms of probiotics, including capsules, powders, or chewable tablets, making it easy to stay consistent with supplementation while traveling.
Seniors (65+ Years)
For seniors, a daily dose of 15–25 billion CFUs is often recommended. However, because older adults are more likely to take multiple medications, it’s important to consult a healthcare provider to determine the best CFU dosage and strains for individual needs.

When and How Long to Take Probiotics
Timing your probiotic routine can play a big role in keeping your gut healthy, especially during travel. Here's how to plan your probiotic intake before, during, and after your trip.
Before You Travel
Start your probiotics at least a week before you leave. This gives your gut time to build up a strong layer of good bacteria. Dr. Steven Peikin from Cooper Health System recommends starting probiotics one week before traveling and continuing for a week after, particularly if you encounter antibiotics or unexpected exposures during your trip.
During this time, make sure you're following the age-appropriate dosages mentioned earlier.
While Traveling
Stick to a daily probiotic routine to help maintain a balanced gut throughout your journey.
After You Return
Keep taking probiotics for at least a week after you get back. Traveler's diarrhea can show up even two weeks after exposure, so continuing your probiotics can support recovery. If you had to take antibiotics during your trip, think about extending your probiotic use to help restore your gut's beneficial bacteria.
Pay attention to how your digestion feels after your trip. If any issues last longer than two weeks, check in with your healthcare provider.
How to Choose Travel-Friendly Probiotics
Traveling can be an exciting adventure, but it often comes with digestive challenges. In fact, nearly 50% of travelers experience some form of digestive discomfort while on the road. To keep your gut in check, selecting the right probiotic is key. Let's break down what to look for, from storage needs to the best strains for travel.
Storage and Stability Requirements
Travel can expose probiotics to fluctuating temperatures and humidity, which can compromise their effectiveness. That's why shelf-stable probiotics are a smart choice - they don’t require refrigeration and can handle a variety of conditions. Always read the product label for storage guidelines. For example, refrigerated probiotics might specify a range like 2°C to 8°C, while shelf-stable ones typically recommend storage below 25°C. If your travel plans involve diverse climates, shelf-stable options are the way to go.
Best Probiotic Strains for Travel
Not all probiotics are created equal, especially when it comes to travel-related digestive issues. Here are some of the top strains to consider:
- Saccharomyces boulardii: Known to reduce traveler’s diarrhea by up to 51%.
- Lactobacillus rhamnosus GG (LGG): Proven to minimize digestive disturbances during travel. A study in Turkey found that LGG users experienced fewer cases of traveler’s diarrhea.
- Bifidobacterium lactis: Particularly helpful for increasing stool frequency, making it a great choice for travelers prone to constipation.
Broad-spectrum probiotics, which combine multiple strains, offer comprehensive digestive support. For instance, a study involving 94 travelers showed that a blend containing strains like BB-12®, LA-5®, STY-31™, and LBY-27™ reduced the incidence of traveler’s diarrhea by 39% when taken two days before travel and continued throughout a two-week trip. These blends are designed to maintain digestive balance, even in challenging environments.
Medical-Grade Probiotic Advantages
For those seeking extra reliability, medical-grade probiotics provide advanced gut support. These formulations often incorporate technologies like microencapsulation and freeze-drying (lyophilization) to protect the probiotics from stomach acid, ensuring they reach the intestines alive and effective. Research suggests that a dose delivering between 100 million and 1 billion viable cells to the intestines is necessary for health benefits.
A standout example is Begin Rebirth RE-1™, which combines prebiotics, probiotics, and postbiotics in a high-potency formula. With 500 billion CFU per serving and Human Origin Strains (HOSt™), it’s designed for maximum effectiveness. Its Lyosublime™ delivery system ensures optimal absorption, and its shelf-stable nature makes it perfect for travel - no refrigeration required.
When selecting a probiotic for your trip, look for products that maintain their potency until the end of their shelf life. Opting for once-daily dosing can also simplify your routine, making it easier to stay consistent during your travels.
Conclusion: Keeping Your Gut Healthy While Traveling
Traveling doesn’t have to upset your digestive system. With a thoughtful probiotic plan, you can enjoy your adventures while maintaining gut balance. It’s important to consider factors like age-appropriate dosage and proper timing for the best results.
Digestive troubles like diarrhea affect about 30–70% of travelers during their trips. To get ahead of potential issues, start taking probiotics at least a week before you leave. For kids under 3, mix a powdered probiotic into a non-carbonated liquid or soft food once daily. Older children can take chewable probiotics about 30 minutes before meals.
Once you’ve set the right dosage, sticking to a daily routine is crucial. Using probiotics consistently throughout your trip helps maintain gut balance. Strains like Lactobacillus rhamnosus GG are especially effective in reducing traveler’s diarrhea.
Beyond probiotics, basic gut health practices can make a big difference. Drink bottled or filtered water to stay hydrated, pack snacks rich in probiotics for added support, and choose your meals carefully. When you get back home, focus on eating fiber-rich and fermented foods to help restore your gut’s natural balance.
For those looking for extra protection, medical-grade probiotics might be worth considering. Products like Begin Rebirth RE-1™ provide robust support with 500 billion CFU per serving and advanced delivery technology that doesn’t require refrigeration.
