Vitamin E toxicity can cause which effect?

Vitamin E toxicity can cause which effect?

• A. Impaired blood coagulation and increased risk for bleeding
• B. Weight gain
• C. Hair loss
• D. Kidney stones

Answer: (A)

Excess vitamin E affects how blood clots. When taken in very high amounts, vitamin E can interfere with vitamin K–dependent coagulation processes, weakening the production or function of clotting factors and amplifying anticoagulant effects. That leads to an increased risk of bleeding, especially in people who are on anticoagulant medications or have a bleeding tendency. This is why bleeding tendency is the most likely consequence of vitamin E toxicity. Weight gain, hair loss, and kidney stones are not typical effects of vitamin E toxicity, so they don’t fit with the known impact on coagulation pathways.
