The recommended dosage of fish oil when taking Lipitor (atorvastatin), a cholesterol-lowering medication, may vary depending on several factors, including the individual's current health status, the presence of other medical conditions, and the specific dosage of Lipitor prescribed. However, there is no established standard dosage for combining fish oil and Lipitor.

It is important to consult with a healthcare provider before starting any new supplement regimen, especially when taking prescription medications. This is because fish oil can affect blood clotting and increase the risk of bleeding, which could potentially interact with the blood-thinning effects of Lipitor [1].

Additionally, it is crucial to be aware that fish oil supplements are not regulated by the Food and Drug Administration (FDA) in the same way that prescription medications are, and the quality and purity of fish oil supplements can vary significantly between brands [2].

Therefore, it is recommended to choose a high-quality fish oil supplement that has been tested for purity and potency by a third-party organization, such as the United States Pharmacopeia (USP) or the National Sanitation Foundation (NSF) [3].

In summary, while fish oil may offer potential heart health benefits, it is important to consult with a healthcare provider before taking fish oil supplements in conjunction with Lipitor or any other prescription medication.
