Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], there are no known drug interactions between Lipitor and supplements. However, it is important to note that certain supplements can interfere with the effectiveness of statins, which are a class of drugs that includes Lipitor. ConsumerLab [2] advises avoiding supplements that contain large amounts of niacin, as this can increase the risk of side effects such as muscle damage. Additionally, some supplements can increase the risk of bleeding when taken with statins, including garlic, ginkgo biloba, and vitamin E. It is important to consult with a healthcare provider before taking any supplements, especially if you are taking prescription medications such as Lipitor. A study published in the Journal of Clinical Lipidology [3] found that some supplements, such as omega-3 fatty acids and coenzyme Q10, may have beneficial effects when taken with statins. However, more research is needed to determine the safety and effectiveness of combining supplements with Lipitor or other statins.
