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 Ezetimibe + Vitamin E pair, each linking to PubMed by PMID where available. Full sourcing methodology at https://nutristackapp.com/methodology/interactions.

Ezetimibe + Vitamin E

Q: Can I take Ezetimibe and Vitamin E together?

Possibly, but with caution. Ezetimibe and Vitamin E have a documented caution-tier interaction. As a fat-soluble vitamin absorbed through the same micellar lipid pathway affected by ezetimibe, vitamin E (tocopherol) absorption may be modestly reduced. Some pharmacology data show small decreases in serum alpha-tocopherol and carotenoids with cholesterol absorption inhibitors. The effect is generally minor and is partly offset because circulating tocopherol is carried on lipoproteins whose levels also fall with therapy.

Q: How does this affect a NutriStack Stack Score?

-5 to your Stack Score per scored caution row.

What is happening. As a fat-soluble vitamin absorbed through the same micellar lipid pathway affected by ezetimibe, vitamin E (tocopherol) absorption may be modestly reduced. Some pharmacology data show small decreases in serum alpha-tocopherol and carotenoids with cholesterol absorption inhibitors. The effect is generally minor and is partly offset because circulating tocopherol is carried on lipoproteins whose levels also fall with therapy.

Mechanism. Ezetimibe reduces NPC1L1-mediated intestinal sterol uptake and the efficiency of micellar fat absorption, which can lower co-absorbed lipophilic micronutrients such as alpha-tocopherol and carotenoids.

Recommendation. No change to standard vitamin E intake is needed. Patients relying on vitamin E supplementation for a specific indication can take it with a fat-containing meal to optimize uptake. Routine monitoring is not required for typical dietary or supplemental doses.
