When taking an anticoagulant, which supplement should be avoided?

The use of anticoagulants, such as warfarin, requires careful management of dietary supplements and certain vitamins due to their interaction with blood clotting mechanisms. Vitamin E is known to have anticoagulant properties itself, which can exacerbate the effects of prescription anticoagulants, leading to an increased risk of bleeding.

High doses of Vitamin E, specifically above 400 IU per day, can further enhance this effect, making blood thinner than intended and increasing the risk of hemorrhage. Therefore, it's critical for individuals on anticoagulant therapy to avoid high doses of Vitamin E supplements to ensure safe treatment and reduce the likelihood of adverse effects associated with bleeding. This caution underscores the importance of monitoring all supplement intake while on anticoagulants, particularly those with the potential to influence blood coagulation.
