    Probiotics and H. pylori: eradication requires a defined treatment plan

    A probiotic should not be assumed to eradicate H. pylori infection. Even the narrower question of improving an eradication regimen’s success or tolerability remains insufficiently supported in the 2024 ACG guideline.

    An add-on claim is different from eradication alone

    The ACG guideline-author presentation reports insufficient evidence that probiotics improve the efficacy or tolerability of H. pylori eradication therapy. This is a conditional conclusion based on low-quality evidence, not proof that every possible strain has no effect. [1]

    It also does not justify choosing a retail strain said to kill the infection without a prescribed regimen. Laboratory inhibition and cure of a human infection are different endpoints. [1]

    Symptoms alone do not establish cure

    The ACG summary describes defined treatment regimens and emphasizes confirmation of eradication after treatment with appropriate testing. The treating clinician determines the regimen and test preparation. [2]

    Feeling better after a supplement is not a replacement for that confirmation. Do not infer that an ulcer-related infection has been cleared from a change in digestive comfort alone. [2]

    Keep the measured endpoint attached to the claim

    Imagine a study reports less treatment-related diarrhea with an add-on product. That finding, by itself, does not demonstrate that the product alone eradicates H. pylori.
