What is this page for?
First and foremost: checking Gastrus against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy
Gastrus is a dietary supplement by BioGaia with 2 active ingredients.We don’t currently list a known drug interaction for its mapped ingredients — but that doesn’t guarantee none exist, so always confirm with your pharmacist.
HelloPharmacist Scorecard of Gastrus by BioGaia
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
None of the active ingredients could be matched to our evidence database, so intended use can't be graded.
Why this rating?
- None of the active ingredients could be matched to a HelloPharmacist monograph, so intended use can't be graded against our evidence data.
Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.
Why this rating?
- The label discloses an exact amount for 0 of its 2 active ingredients.
- “L. reuteri Gastrus Blend” is a proprietary blend — the label doesn't break down how much of each component you get.
None of the active ingredients could be matched to our interaction database.
Why this rating?
- We couldn't match any ingredient to a HelloPharmacist monograph, so there was nothing to check interactions against.
None of the active ingredients could be matched to our safety data.
Why this rating?
- We couldn't match any ingredient to a HelloPharmacist monograph, so there was no safety data to measure.
