Based on the information available, there is no direct evidence to suggest that Lipitor, a medication used to treat high cholesterol, causes Vitamin K deficiency.

Lipitor, also known as Atorvastatin, is a statin drug that works by blocking a substance your body needs to make cholesterol [1]. On the other hand, Vitamin K is a fat-soluble vitamin that the body needs for blood clotting, bone metabolism, and regulating blood calcium levels [2].

While Lipitor and Vitamin K have different functions and roles in the body, some medications can interact with Vitamin K and affect its absorption or function [3]. However, there is no specific mention of Lipitor causing Vitamin K deficiency in the available resources.

It is always recommended to consult with a healthcare provider or pharmacist for personalized advice regarding medication use and potential interactions.
