Lipitor, a brand name for the drug atorvastatin, is a medication used to lower cholesterol levels in the blood [1]. According to a study published in the Journal of Clinical Lipidology, there is no evidence to suggest that low-sodium salt intake interferes with the effectiveness of atorvastatin in reducing cholesterol levels [2]. However, it is important to note that reducing sodium intake can have other health benefits, such as reducing blood pressure, which can further reduce the risk of heart disease [3]. It is always recommended to consult with a healthcare professional before making any changes to medication or dietary habits.
