Nutrients connected to Antibiotic-Associated Diarrhea
A link means the body needs the nutrient for this, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate; each link shows how strong the evidence is.
- Saccharomyces boulardiiClinically supported
ESPGHAN (2016) strongly recommended S. boulardii or L. rhamnosus GG for children on antibiotics who have risk factors (moderate-quality evidence). Evidence in adults is lower certainty.
- Lactobacillus and Bifidobacterium probioticsPreliminary or mixed
A 2017 review of 17 studies found about half the chance of this diarrhoea with probiotics, which the authors called tentative; no benefit shown in older people. Results depend on the strain.
- Lactobacillus rhamnosus GGClinically supported
ESPGHAN (2016) strongly recommends LGG or S. boulardii to prevent this in at-risk children (moderate-quality evidence). It does not cover treatment or other strains.
- Gut Health Blends (Probiotic, Fiber, Enzymes)Preliminary or mixed
NCCIH lists this as an area with some promise for certain probiotics; the 2026 review calls it the strongest area, but only for selected strains.
- Lactobacillus acidophilus and the acidophilus groupPreliminary or mixed
A named three-strain mixture containing L. acidophilus CL1285 showed efficacy in adults while other Lactobacillus strains did not; NCCIH calls the overall benefit tentative.
