Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels and reduce the risk of heart disease [1]. However, it is not specifically designed to manage fat absorption. Instead, it works by inhibiting an enzyme in the liver that is responsible for producing cholesterol [2]. By reducing the amount of cholesterol produced, Lipitor can lower the amount of cholesterol in the bloodstream.

Phytosterols, sterols, and stanols, on the other hand, are plant-based compounds that have been shown to reduce the absorption of cholesterol in the gut [3]. They are often added to foods like margarine, orange juice, and yogurt to help lower cholesterol levels.

In summary, Lipitor is not designed to manage fat absorption, but rather to lower cholesterol levels by inhibiting cholesterol production in the liver. Phytosterols, sterols, and stanols, on the other hand, are plant-based compounds that can help reduce the absorption of cholesterol in the gut.
