Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body [1]. According to ConsumerLab, taking a statin drug such as Lipitor may reduce the absorption of omega-3 fatty acids from fish oil supplements [2]. However, it is important to note that this effect is not significant enough to negate the benefits of taking fish oil supplements altogether. Fish oil supplements contain high levels of omega-3 fatty acids, which have been shown to have numerous health benefits, including reducing inflammation and improving heart health [3]. While taking Lipitor may reduce the absorption of these fatty acids, it is still recommended to continue taking fish oil supplements for their overall health benefits [2].
