Vitamin E and platelet aggregation.

P C Huijgens, C A van den Berg, L M Imandt

    Acta Haematologica
    |January 1, 1981

    Summary

    High doses of vitamin E (2,000 IU daily for 10 days) do not affect bleeding time or platelet function in healthy individuals. Vitamin E is not recommended for therapies aimed at suppressing platelet activity.

    Area of Science:

    • Biochemistry
    • Hematology
    • Pharmacology

    Background:

    • Vitamin E is an antioxidant with potential effects on platelet function.
    • Understanding vitamin E's impact on hemostasis is crucial for clinical applications.

    Purpose of the Study:

    • To investigate the effects of a high daily dose of vitamin E on platelet aggregation and bleeding time in healthy subjects.
    • To determine if vitamin E influences platelet prostaglandin synthesis.

    Main Methods:

    • Healthy volunteers received 2,000 IU of vitamin E daily for 10 days.
    • Bleeding time was measured.
    • Collagen- and ADP-induced platelet aggregation were assessed.
    • Platelet prostaglandin synthesis was analyzed.

    Main Results:

    • Vitamin E administration did not prolong bleeding time.
    • No significant influence was observed on collagen- or ADP-induced platelet aggregation.
    • Platelet prostaglandin synthesis remained unaffected.

    Conclusions:

    • High-dose vitamin E (2,000 IU/day) does not impair platelet function or prolong bleeding time in healthy individuals.
    • Vitamin E is not suitable for therapies requiring suppression of platelet activity.
