Can You Take Losartan and Vitamin D Together?
No documented interaction was identified between losartan and vitamin D in the sources reviewed.
See the full Losartan page and Vitamin D page for other reviewed interactions and reference information.
What the interaction means
Losartan's FDA label documents four drug-interaction categories -- potassium-raising drugs, lithium, NSAIDs, and dual RAS blockade with other ARBs/ACE inhibitors -- and vitamin D is not among them. MedlinePlus's vitamin D page does not mention losartan, ARBs, or angiotensin.
No documented interaction between Losartan and Vitamin D was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.
Practical context
Losartan's FDA label and vitamin D's MedlinePlus page were checked directly, full text, in both directions. Losartan's own named interaction categories do not include vitamin D or other vitamins.
