What kind of interaction is it?

Caution: an interaction that may reduce efficacy or raise side-effect risk and warrants monitoring.

Is this interaction backed by published research?

Yes. NutriStack lists 1 citation row for the Berberine + Hesperidin pair, each linking to PubMed by PMID where available. Full sourcing methodology at https://nutristackapp.com/methodology/interactions.

Berberine + Hesperidin

Q: Can I take Berberine and Hesperidin together?

Possibly, but with caution. Berberine and Hesperidin have a documented caution-tier interaction. Both hesperetin and berberine inhibit intestinal and hepatic CYP3A4 and modulate efflux transporters, which could alter the metabolism of co-administered CYP3A4 substrates.

Q: How does this affect a NutriStack Stack Score?

-5 to your Stack Score per scored caution row.

CautionEmerging evidence

What is happening. Both hesperetin and berberine inhibit intestinal and hepatic CYP3A4 and modulate efflux transporters, which could alter the metabolism of co-administered CYP3A4 substrates.

Mechanism. Hesperetin is a known inhibitor of CYP3A4 and P-glycoprotein; berberine likewise inhibits CYP3A4 and P-gp. Combined enzyme/transporter inhibition can raise plasma levels of certain drugs metabolized by these pathways.

Recommendation. The combination itself is generally tolerated, but exercise caution if also taking narrow-therapeutic-index CYP3A4 substrate medications and consult a clinician or pharmacist.
