The first source [1] provides information on the drug Lipitor and its patent expiration. The second source [2] explains that while there is no known interaction between statins (a class of drugs that includes Lipitor) and omega-3 supplements, some studies suggest that omega-3 supplements may enhance the cholesterol-lowering effects of statins. However, more research is needed to confirm this potential benefit.

The third source [3] also states that there are no known interactions between Lipitor and omega-3 supplements. However, it notes that some studies have suggested that omega-3 supplements may reduce inflammation and improve cardiovascular health, which could be beneficial for individuals taking Lipitor to manage their cholesterol levels.

In summary, based on the sources provided, there is no known interaction between Lipitor and omega-3 supplements. While some studies suggest that omega-3 supplements may enhance the cholesterol-lowering effects of statins like Lipitor, more research is needed to confirm this potential benefit. It is always important to consult with a healthcare provider before starting any new medications or supplements.
