Lipitor is a brand name for atorvastatin, a medication 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 some supplements may affect the effectiveness of statins, a class of drugs that includes Lipitor.

ConsumerLab [2] recommends avoiding supplements that contain large amounts of vitamin K, as this vitamin can interfere with the anticoagulant effects of statins. Additionally, the website advises caution when taking supplements that contain red yeast rice, as this supplement contains a compound that is similar to the active ingredient in statins and may increase the risk of side effects.

SingleCare [3] notes that grapefruit juice should be avoided when taking Lipitor, as it can increase the levels of the medication in the blood and increase the risk of side effects. The website also advises caution when taking supplements that contain St. John's Wort, as this supplement may decrease the effectiveness of Lipitor.

In conclusion, while there are no known interactions between Lipitor and supplements, it is important to be cautious when taking supplements that may affect the effectiveness or increase the risk of side effects of statins. Patients should always consult with their healthcare provider before taking any supplements while on Lipitor or any other medication.
