This supplement contains four high-quality strains of live cultures which are all scientifically proven to reach the gut alive and to survive at higher temperatures, making this a suitable travel companion for destinations with hotter, more humid climates.  Each capsule provides five billion live cultures including the following specific strains:

  • Bifidobacterium longumRosell-175
  • Lactobacillus rhamnosusRosell-11
  • Saccharomyces boulardii
  • Lactobacillus acidophilusRosell-52

The high-quality nature of this supplement gives increased confidence to enjoy your holidays worry-free. Make this shelf-stable and cabin-friendly product your travel essential for all holidays abroad.

Lactobacillus acidophilus Rosell-52 is a natural resident of the intestinal microflora. It has been through numerous in vitro tests which indicate its ability to reach the gut alive.

Saccharomyces boulardii is a unique live culture sold widely across all of Europe, especially in France and Germany. S. boulardii has undergone extensive scientific research confirming its safety.

Lactobacillus rhamnosus Rosell-11 is a natural component of the intestinal-friendly bacteria, and the rhamnosus species is one of the most studied live cultures in the world. L. rhamnosus Rosell-11 from OptiBac 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.

Bifidobacterium longum Rosell-175 is a well-researched strain that has been shown to reach the gut alive.
