Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. Fish oil is a dietary supplement that contains omega-3 fatty acids, which have been shown to have various health benefits, including reducing inflammation and improving heart health.

According to Drugs.com, there are no known interactions between fish oil and Lipitor [2]. However, it is always important to consult with a healthcare provider before starting any new medication or supplement, as individual circumstances may vary.

A study published in the Journal of Clinical Lipidology found that combining fish oil supplements with statins, such as Lipitor, may provide additional cardiovascular benefits [3]. However, it is important to note that this study was conducted in a specific population and may not apply to everyone.

In general, both fish oil and statins have been shown to be effective in reducing the risk of cardiovascular disease [3][4]. However, it is important to follow a healthy diet and lifestyle in addition to any medication or supplement regimen.
