Travel is one of life’s great pleasures – but it’s also one of the fastest ways to knock your body off balance. Early flights, late nights, new foods, different routines, unfamiliar beds, cabin air and that “holiday cocktail” of caffeine, sun, alcohol and excitement… It all adds up and takes a toll. “Flying is basically a full-body stress test” says Dr Naomi Newman-Beinart, PhD – a health expert, chartered psychologist and nutritionist.
“The cabin air is drier than most deserts, meaning you dehydrate much more quickly than you realise, slowing digestion, draining energy and weakening your immune defences. Sitting still for hours causes your gut to become sluggish, so that’s why bloating and discomfort are so common after long-haul flights. Then there’s jet lag. When your body clock is erratic, everything from digestive enzymes to mood hormones are affected,” she explains.
Moving between totally different climates – from New York’s cooler temps to the heat of Mumbai, for example – adds an extra layer of physiological whiplash. No wonder so many travellers feel tired, puffy or vaguely run-down by day two. Your body is busy recalibrating to new temperatures, new humidity levels, new time zones… And then we throw totally different eating patterns on top.
The three pillars that matter most on the road? Hydration, gut support and steady energy. And one of the biggest, most overlooked factors in how you feel when you travel is what (and how) you eat once you arrive. “When it comes to gut health and travelling, small, realistic habits work best. Start with hydration as this is the simplest way to keep digestion moving. Try to include one fibre-rich meal each day, take a daily probiotic or include fermented foods when you can. It’s all about gentle balance, not rigid rules,” Naomi says.
Cooler climates ask more of the body. They’re often physically demanding – think long hiking days, icy treks, ski sessions that leave muscles burning – and they tend to come with far less sunlight than we’re used to. A few well-chosen supplements can make the whole experience smoother. “I recommend Vitamin D for mood, immunity and bone support when sunlight is minimal; Omega-3s for inflammation and joint comfort, especially after a day on the slopes; and Magnesium for muscle recovery and deeper sleep, as cold climates and altitude can disrupt both”, Naomi advises. “Cordyceps mushrooms are brilliant for stamina, oxygen use and recovery, making them particularly useful at high altitude.”
Hot, humid destinations come with their own set of wellbeing challenges – relentless heat, constant sun exposure and the kind of busy, active days that leave you pleasantly exhausted but physiologically depleted. To keep everything balanced, Naomi recommends a few smart supplements that make a real difference. “Electrolytes are essential – heat increases mineral loss and replacing those minerals keeps energy stable while preventing headaches and muscle cramps. B vitamins help maintain steady energy on long days packed with walking, exploring and swimming. Adaptogens like ashwagandha support a calmer stress response when everything feels go-go-go. And Saccharomyces boulardii, a traveller-friendly probiotic, helps keep gut balance in check no matter where the local cuisine leads you.”
Now that you know what your body actually needs when you’re travelling, here are the supplements that are genuinely worth packing – the best formulas, smart travel-friendly formats and the ones that earn their place in your carry-on every time.
