Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. It belongs to a class of drugs called statins that work by inhibiting an enzyme involved in cholesterol synthesis [1].

There is no evidence to suggest that Lipitor affects dietary fat absorption. Instead, it works by reducing the production of cholesterol in the liver, which leads to a decrease in the amount of LDL (low-density lipoprotein) cholesterol in the bloodstream [2].

It is important to note that taking Lipitor may lead to a deficiency in fat-soluble vitamins such as vitamin D, as these vitamins require cholesterol for their absorption in the body. Therefore, individuals taking Lipitor may need to supplement their diet with vitamin D or undergo regular testing to ensure they are not deficient [3].

In summary, Lipitor does not affect dietary fat absorption. Instead, it works by reducing cholesterol production in the liver, which leads to a decrease in LDL cholesterol levels. However, taking Lipitor may lead to a deficiency in fat-soluble vitamins such as vitamin D, which may require supplementation or monitoring.
