A probiotic of the Bifidobacterium genus has been identified by Spanish researchers as being particularly effective in the treatment of ulcers. The strain B. bifidum CECT 7366 showed fantastic results from in vitro testing, exhibiting the inhibition of Helicobacter pylori - the main cause of many gastritis, gastric & duodenal ulcers - by up to 95%. The strains activity was further tested in mice with a 21 day trial revealing that mice given the probiotic strain developed significantly less ulcers than those who did not. The researchers concluded, "The results presented here confer to strain B. bifidum CECT 7366 the status of a probiotic bacterium with functional activity against H. pylori."

See the evidence for the Lacidofil formula also noted for its efficacy against H. pylori. For more information on the Bifidobacterium genus, take a look at the Probiotics Database here.

  • Hi there,

    Can you recommend a product for somebody with gastritis probably brought on by NSAID use? Thank you so much. I already use the pink saccharomyces boulardi one.

  • Dear Claire,

    Thanks for your question.
    This can be a very unpleasant side effect of NSAID medication, but this area of research is very encouraging. You may also wish to read our other related blog on acid reflux:

  • Does anyone know when this strain B. bifidum CECT 7366 will be available to buy?

    Dear V,

    Thank you for your question.
    I'm not aware of this strain being available yet as a supplement.
    There are other strains of live cultures that may be able to offer some protection against H. pylori infection. I'll email you directly with some suggestions.

    Best wishes,
