Lipitor, a medication commonly prescribed to lower cholesterol levels, does not directly affect Vitamin K levels in the human body. Lipitor, also known as atorvastatin, is a type of statin that works by blocking the production of cholesterol in the body [1].

Vitamin K is a fat-soluble vitamin that plays a crucial role in blood clotting and bone metabolism [2]. It is not known to interact directly with Lipitor or any other statins [3].

However, it is important to note that some studies suggest that statins may affect the absorption and metabolism of fat-soluble vitamins, including Vitamin K, due to their effect on the digestive system [4]. However, these effects are not specific to Lipitor and further research is needed to fully understand the relationship between statins and Vitamin K.

In summary, based on the available information, Lipitor does not directly affect Vitamin K levels. However, it is possible that Lipitor and other statins may have an indirect effect on the absorption and metabolism of Vitamin K due to their impact on the digestive system.
