There's something magical about landing somewhere new. New streets to wander, new dishes to try, new flavours you'd never dream of cooking at home. It's all part of the fun. But while you're busy falling in love with a new place, your gut is working overtime to keep up.
Research shows that international travel can alter the composition of the gut microbiome, sometimes in a matter of days. Changes in diet, meal timing, sleep, stress, unfamiliar water sources and new microbes all play a part in reshaping that internal ecosystem. Some people barely notice. Others end up dealing with digestive discomfort or traveller's diarrhoea.1,2
As a Nutritional Therapist, I don't wait until I'm at the airport to start thinking about my gut.
NeuBiotic is the very first thing that goes into my suitcase, and I start taking it a few days before I fly. My philosophy is simple: support the gut microbiome before I’m exposed to everything that comes with being away, rather than trying to deal with problems after they’ve started.
That doesn't mean I play it safe with food. Quite the opposite. Trying traditional dishes and eating the way locals do is one of my favourite parts of any trip. I'm not counting vegetables or sticking rigidly to my usual routine while I'm away. Holidays are for living a little.
Getting my gut ready beforehand is what lets me enjoy the street food, the strange new breakfasts, the second helpings, without spending half the trip worrying about how my stomach will cope.
Gut health rarely makes the pre-trip checklist. Passports, travel insurance and sun cream take priority every time. But after years working in nutrition, it's become one of the first things I prepare, along with all the essentials.
For me, NeuBiotic has earned a permanent place in my travel bag. I genuinely wouldn't travel without it.
