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 Dulaglutide + Psyllium Husk pair, each linking to PubMed by PMID where available. Full sourcing methodology at https://nutristackapp.com/methodology/interactions.

Dulaglutide and Psyllium Husk, a synergy.

Q: Can I take Dulaglutide and Psyllium Husk together?

Yes. The combination of Dulaglutide and Psyllium Husk produces a measurable benefit. Psyllium husk reduces postprandial glucose and HbA1c in type 2 diabetes by slowing carbohydrate absorption. Dulaglutide also slows gastric emptying and lowers postprandial glucose. The combination reduces postprandial spikes without driving hypoglycemia, though additive GI slowing can intensify bloating or early satiety. Dulaglutide is injected so psyllium's drug-binding does not apply.

Q: How does this affect a NutriStack Stack Score?

+2 to your Stack Score per scored synergy row.

Synergy

What is happening. Psyllium husk reduces postprandial glucose and HbA1c in type 2 diabetes by slowing carbohydrate absorption. Dulaglutide also slows gastric emptying and lowers postprandial glucose. The combination reduces postprandial spikes without driving hypoglycemia, though additive GI slowing can intensify bloating or early satiety. Dulaglutide is injected so psyllium's drug-binding does not apply.

Mechanism. Psyllium forms a viscous gel in the gut that slows gastric emptying and reduces postprandial glucose absorption. Dulaglutide activates GLP-1 receptors, slowing gastric emptying and augmenting glucose-dependent insulin secretion. Both lower postprandial glucose.

Recommendation. Psyllium (5-10 g/day, split with meals) is a reasonable adjunct on dulaglutide. Drink plenty of water and increase the dose gradually to limit bloating. Separate psyllium from any oral medications by at least 2-4 hours.
