What kind of interaction is it?

Synergy: a documented combination effect that is stronger or more useful than either substance taken alone.

Is this interaction backed by published research?

Yes. NutriStack lists 2 citation rows for the Amoxicillin-Clavulanate + Probiotics pair, each linking to PubMed by PMID where available. Full sourcing methodology at https://nutristackapp.com/methodology/interactions.

Amoxicillin-Clavulanate and Probiotics, a synergy.

Q: Can I take Amoxicillin-Clavulanate and Probiotics together?

Yes. The combination of Amoxicillin-Clavulanate and Probiotics produces a measurable benefit. Amoxicillin-clavulanate has notably higher rates of antibiotic-associated diarrhea than plain amoxicillin, largely due to the clavulanate component. Probiotic supplementation reduces this AAD risk and is particularly recommended during amoxicillin-clavulanate courses.

Q: How does this affect a NutriStack Stack Score?

+2 to your Stack Score per scored synergy row.

Amoxicillin-clavulanate has notably higher rates of antibiotic-associated diarrhea than plain amoxicillin, largely due to the clavulanate component. Probiotic supplementation reduces this AAD risk and is particularly recommended during amoxicillin-clavulanate courses.

Synergy

What is happening. Amoxicillin-clavulanate has notably higher rates of antibiotic-associated diarrhea than plain amoxicillin, largely due to the clavulanate component. Probiotic supplementation reduces this AAD risk and is particularly recommended during amoxicillin-clavulanate courses.

Mechanism. Probiotics restore colonization resistance disrupted by the broad-spectrum activity of amoxicillin-clavulanate. Clavulanate independently increases gut motility, and probiotics help offset this dysmotility.

Recommendation. Take probiotics throughout your amoxicillin-clavulanate course, separated by at least 2 hours from each antibiotic dose. Continue for at least 1 week after the antibiotic ends.

Minimum separation. 120
