Which vitamins are most likely to cause toxicity if taken in high doses?

Certain vitamins are more likely to cause toxicity when taken in high doses, primarily the fat-soluble vitamins. Here are the vitamins most commonly associated with toxicity:

1. Vitamin A: Excessive intake can lead to symptoms such as liver damage, headaches, and blurred vision.
2. Vitamin D: High doses can result in hypercalcemia, which can cause nausea, weakness, and kidney problems.
3. Vitamin E: While generally safe, high doses can interfere with vitamin K and cause bleeding problems.
4. Vitamin K: Typically less toxic, but excessive amounts can affect anticoagulant medications.
