Why should individuals on anticoagulation medication avoid excess vitamin E?

What will be an ideal response?


Excessive intakes of vitamin A and vitamin E negatively affect the actions of vitamin K. Vitamin A is thought to interfere with the absorption of vitamin K from the small intestine, whereas large doses of vitamin E can lead to a decrease in vitamin K-dependent clotting factors and increased bleeding tendency. In either case, megadose supplements of these vitamins increase the risk of vitamin K deficiency and bleeding, as noted in earlier discussions of the Upper Levels of the vitamins.
