When eating and drinking different foods in unfamiliar environments it can be common to experience stomach upsets, and this is thought by some to be caused by an upset of one's natural gut flora.

The high quality nature of this supplement gives travellers the increased confidence to enjoy their holidays anxiety-free. Make this shelf-stable and cabin friendly product your travel essential for far flung locations such as Egypt, India and Thailand.

Lactobacillus acidophilus Rosell-52 is a natural resident of the intestinal microflora; this strain of acidophilus has been well studied to survive your stomach acidity and biliary salts; and to travel to the intestines without damage. L. acidophilus Rosell-52 has also been through numerous in vitro tests.

Saccharomyces boulardii is a unique yeast sold widely across Europe, especially in France and Germany.S. boulardii has undergone extensive scientific research documenting its safety, and investigating its properties when in contact with pathogenic bacteria such as E. coli and Salmonella.

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