Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], there are no known supplements that interact with Lipitor. However, it is important to note that certain supplements can interfere with the effectiveness of statins, a class of drugs that includes Lipitor. For example, SingleCare [2] warns that supplements containing high levels of niacin, such as vitamin B3, can increase the risk of muscle damage when taken with statins. Additionally, supplements containing red yeast rice can also increase the risk of muscle damage and should be avoided when taking statins. ConsumerLab [3] recommends avoiding supplements containing St. John's wort, which can decrease the effectiveness of statins, and grapefruit juice, which can increase the risk of side effects. It is important to speak with a healthcare provider before taking any supplements while on Lipitor or any other statin medication.
