Based on the available information, there is a potential for certain supplements to interact with Lipitor, a cholesterol-lowering drug commonly known as atorvastatin.

The National Prublic Radio (NPR) article [1] discusses a study that compared the effectiveness of statins, such as Lipitor, with supplements for reducing cholesterol. The study found that statins were vastly superior in cutting cholesterol levels. While the article does not explicitly mention specific supplements that may affect Lipitor's efficacy, it highlights the importance of consulting healthcare professionals before starting any supplements.

The American Heart Association (AHA) provides information on medication interactions with food, supplements, and other drugs [3]. According to the AHA, some supplements can interact with cholesterol-lowering medications, potentially reducing their effectiveness. The AHA advises patients to consult their healthcare providers before taking any supplements, especially if they are on medications.

The Drug Patent Watch website [2] provides information on the tradename Lipitor, but it does not contain specific information on supplements that may affect its efficacy.

In summary, while specific supplements that may affect Lipitor's efficacy are not mentioned in the available information, it is crucial to consult healthcare professionals before starting any supplements, as they can potentially interact with cholesterol-lowering medications and reduce their effectiveness.
