Do you find you get stomach upsets when you go on holiday? Well, the reason may well be that the unfamiliar food and drink you’re enjoying is in fact causing an imbalance in your natural gut flora.

That’s why we recommend that everyone with a sensitive tum takes OptiBac Probiotics for Travelling Abroad, especially if you’re going on a long-haul trip to a country like India, Egypt, Thailand or Mexico. This supplement contains four robust high-quality strains of live cultures that have been chosen because they can survive in hotter, more humid climates without being stored in the fridge.

They’re guaranteed to last until their expiry date, whatever the conditions they’re put through – so ideal to tuck into your teenager’s backpack or put into a family suitcase. The four strains of bacteria are:

Lactobacillus acidophilus Rosell-52 is a natural resident of the intestinal microflora. This type of acidophilus has been well studied to survive your stomach acidity and biliary salts and to travel to the intestines without damage.

Lactobacillus rhamnosus Rosell-11 is a natural component of the intestinal- friendly bacteria and one of the most studied in the world of live cultures. It too has been proven to resist bile and gastric acidity over pH 3 – so if taken at mealtimes (when pH is around 4) it will pass through the stomach without being damaged.

Bifidobacterium longum Rosell-175 colonises primarily in the large intestine or colon.

Saccharomyces boulardii is a unique yeast sold widely across Europe, especially in France and Germany. It is particularly appropriate for travelling because it sticks to harmful bacteria such as E coli and salmonella and gently removes it from the system.

The vegetarian capsules are suitable for both adults and children over one year old, and it is advised to start taking them 3-5 days before departure and continue for a couple of days upon your return.

OptiBac Probiotics for Travelling Abroad are available at The Hub for £10.49 for 20 capsules (one a day) or £24.99 for a jumbo pack of 60 capsules
