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 2 citation rows for the Dulaglutide + Fenugreek pair, each linking to PubMed by PMID where available. Full sourcing methodology at https://nutristackapp.com/methodology/interactions.

Dulaglutide + Fenugreek

Q: Can I take Dulaglutide and Fenugreek together?

Possibly, but with caution. Dulaglutide and Fenugreek have a documented caution-tier interaction. Fenugreek fiber can slow carbohydrate absorption and may lower glucose modestly. Dulaglutide also lowers glucose and delays gastric emptying, so combined use can increase gastrointestinal effects and may add to glucose lowering.

Q: How does this affect a NutriStack Stack Score?

-5 to your Stack Score per scored caution row.

CautionEmerging evidence

What is happening. Fenugreek fiber can slow carbohydrate absorption and may lower glucose modestly. Dulaglutide also lowers glucose and delays gastric emptying, so combined use can increase gastrointestinal effects and may add to glucose lowering.

Mechanism. Fenugreek's soluble fiber and seed constituents may slow carbohydrate absorption. Dulaglutide activates GLP-1 receptors, slows gastric emptying, and augments glucose-dependent insulin release.

Recommendation. Use fenugreek cautiously with dulaglutide if you have diabetes or significant nausea, reflux, vomiting, constipation, or diarrhea. Tell the prescriber if insulin or a sulfonylurea is also used, and follow the diabetes glucose-monitoring plan during starts, stops, and dose changes.
