    Area of Science:

    • Biochemistry
    • Hematology
    • Nutritional Science

    Background:

    • Vitamin E is an antioxidant.
    • Vitamin K is essential for blood coagulation.
    • Warfarin is a vitamin K antagonist.

    Purpose of the Study:

    • To investigate the effect of high-dose vitamin E on coagulation in normal dogs.
    • To determine if vitamin E exacerbates coagulopathy in vitamin K-deficient dogs.

    Main Methods:

    • Normal dogs were administered high-dose vitamin E.
    • Dogs were made mildly vitamin K-deficient using warfarin.
    • Coagulation mechanisms and factors were assessed.

    Main Results:

    • Vitamin E did not alter coagulation in normal dogs.
    • In vitamin K-deficient dogs, vitamin E induced severe coagulopathy.
    • This effect was linked to reduced vitamin K-dependent factors, not non-dependent factors.

    Conclusions:

    • Vitamin E may pose a risk of coagulopathy in individuals with vitamin K deficiency.
    • Further research is needed to explore vitamin E's role in thrombotic diseases and its hematological toxicity in vitamin K-deficient patients.
