Best Probiotics for Travel

5 Best Probiotics for Traveling Abroad (UK, Bali, Mexico, Thailand)

Studies show that up to 56% of tourists face gut issues like Traveler’s diarrhea, acidity, and constipation. These issues can make your trip memories quite unpleasant. 

So, what’s your preventive measure to safeguard your gut from exotic germs and digestion troubles?

Good News, you’ve landed at the right place! Because probiotics are a proven solution for travel-time gut issues. 

Here is my list of 7 effective travel-friendly probiotics among the plethora of options available on the market;

Key Highlights

But before I dive into their product features, let me share my selection criteria with you.

I hope you find it helpful.

Here’s How I Selected the Best Probiotics for Travel

Looked for Shelf-stable Strains

When traveling, it’s hard to carry and maintain cold storage. So, refrigerated probiotics are a big no for traveling, especially when visiting hot regions.

That’s why make sure your probiotics are thermostable and can survive at room temperature without refrigeration for many days or even weeks.

To help make the decision, all brands I have put on the following list are shelf stable, so rest assured you can take them while traveling to any place in the world.

Picked Only Delayed-Release Capsules 

Probiotics can only benefit you when they are settled in your intestines. To reach the intestinal tract, they must first pass through the stomach, where gastric acids can kill many of these pH-sensitive creatures.

Therefore probiotics with quick-release encapsulation aren’t going to do any good. 

Instead, you should opt for delayed-release, acid-resistant capsules. These capsules are made from plant fiber, usually with HPMC or MAKtrek technology.

With delayed-release technology, the capsules only open after reaching the intestines, where the pH is “just suitable” for probiotic strains.

Strains That Make The Best Probiotics for Travelers

Probiotics’ efficacy is always strain-specific. So, not all of them will work equally well for travelers. 

For example, L. acidophilus is a strain with proven efficacy against antibiotics-associated diarrhea. However its efficacy for Traveler’s diarrhea and similar issues is not confirmed unless it is paired with B. bifidum. 

Let me share how and why.

According to a clinical trial from the Pasteur Institute, Paris acidophilus does not prevent or cure traveler’s diarrhea. 

However, this meta-analysis from the Journal of Travel Medicine and Infectious Diseases proves that a mixture of L. acidophilus and B. bifidum can reduce the chances of Traveler’s diarrhea.

Hence, multi-strain probiotics containing L. acidophilus are likely to be more beneficial during travel than acidophilus only.

But some strains are quite potent even when taken alone. These are:

  • Lactobacillus Rhamnosus GG,
  • And yeast strain Saccharomyces Boulardii

The efficacy of S. boulardii for travelers’ gut health is backed by research and user feedback.

Studies suggest it helps with travel-related health issues better than any other strain, even the LGG probiotic.

I found the tourists confirming its efficacy on TripAdvisor. Dianne from Australia shared that probiotics kept her gut healthy during her visit to South Asian countries. 

probiotic review on trip advisor

She mentioned that Saccharomyces boulardii is the best probiotic for traveling to Bali and other tropical locations with hot and humid weather.

Similarly, studies show L. rhamnosus GG pills significantly reduce the chances and intensity of Traveler’s diarrhea.

The Journal of travel medicine published research on the diarrheal prevention efficacy of LGG probiotics for travelers. Results show that tourists taking LGG probiotics experienced travelers’ diarrhea less often than placebo.

Also, this strain can resist acid and bile secretions and adheres to the intestinal walls better than many other friendly strains.

So, it stays viable in the gut for longer, helping you quickly get used to the foreign meals without becoming sick. 

Infection Preventing bacteria

Besides the strains mentioned earlier, probiotics that can fight diarrhea and infection-causing germs are a good choice for travelers. 

That’s because visiting foreign places can expose you to germs through food, drinks, and air.

E. coli is the most common germ implicated in Traveler’s diarrhea. Other species like Clostridium difficile, Campylobacter jejuni, Shigella, and Salmonella strains can also cause such troubles.

So, your gut should be able to resist the pathogenic attack when you are away from home. 

Lactobacillus strains (L. plantarum, L. paracasei, L. casei, L. bulgaricus), Bifidobacterium strains (B. longum), and S. thermophilus are the most effective species for pathogen resistance.

A 2020 study reports that L. plantarum protects the gut from diarrhea-causing germs like E. coli by promoting the detoxification of their harmful secretion.

Similar results are reported for L. paracasei in a 2022 study from Frontiers in Nutrition.

Another research found a probiotic blend of L. casei, L. bulgaricus, and S. thermophilus effective for C. difficile-associated Traveler’s diarrhea.

So, if you, unfortunately, get germs inside your body, L. plantarum colonies won’t let them bother your gut health.

When traveling, probiotics will help you digest foreign meals easily and avoid getting sick by fighting disease-causing microbes you may have ingested or inhaled.

The best strains to take before travel are L. rhamnosus GG, and S. boulardii, as they have science-backed efficacy against traveler’s diarrhea and other gut troubles.

What are the best probiotics to take when traveling to different countries?

When traveling to different countries, it’s important to consider the potential changes in diet and environment that can affect your digestive health.

For traveling to countries like the UK, Mexico, Bali, India, Thailand, and other countries with different food and water sources, it’s recommended to take probiotics with a variety of strains, including Lactobacillus acidophilus, Bifidobacterium lactis, and Saccharomyces boulardii. These strains have been shown to help prevent travelers’ diarrhea and support overall digestive health.

My recommended probiotics for travel include Yourbiology Gut+, which contains 4 live active strains of probiotics and is a good value for money, and Culturelle, which contains Lactobacillus rhamnosus GG, a strain that has been shown to reduce the risk of travelers’ diarrhea.

It’s also important to consider whether the probiotics need to be refrigerated during travel. Look for travel-friendly probiotics that are formatted to survive hotter climates and do not require refrigeration. Remember to follow the recommended dosage instructions for the probiotics you choose.
