Can You Take Vitamin K and Zinc Together?
No documented interaction was identified between zinc and vitamin K in the sources reviewed.
See the full Vitamin K page and Zinc page for other reviewed interactions and reference information.
What the interaction means
Zinc's own NIH fact sheet interactions section names only quinolone antibiotics, tetracycline antibiotics, penicillamine, and thiazide diuretics -- vitamin K is not among them. MedlinePlus's vitamin K page does not mention zinc.
No documented interaction between Vitamin K and Zinc 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
Zinc's NIH ODS fact sheet and MedlinePlus's vitamin K page were checked directly, full text, in both directions. Zinc's own named interaction categories do not include vitamins.
