Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the body. While taking Lipitor, it is essential to avoid certain supplements that can interact with the drug and cause unwanted side effects. According to the sources provided, there are several supplements to avoid when taking Lipitor.

ConsumerLab [2] warns that supplements containing high doses of vitamin D, vitamin E, and fish oil should be avoided when taking statins like Lipitor. High doses of vitamin D and E can increase the risk of bleeding, while fish oil can increase the risk of muscle damage. Additionally, supplements containing red yeast rice should be avoided as it can also lower cholesterol levels and increase the risk of side effects.

SingleCare [3] also recommends avoiding grapefruit and grapefruit juice while taking Lipitor. Grapefruit can increase the concentration of the drug in the bloodstream, leading to an increased risk of side effects.

Drug Patent Watch [1] does not provide specific information on supplements to avoid with Lipitor, but it does list several drug interactions that can occur with the medication. It is essential to inform your doctor of any medications or supplements you are taking before starting Lipitor to avoid any potential interactions.

In conclusion, while taking Lipitor, it is crucial to avoid supplements containing high doses of vitamin D, vitamin E, and fish oil, as well as red yeast rice. Grapefruit and grapefruit juice should also be avoided. It is important to inform your doctor of any medications or supplements you are taking to avoid any potential interactions.
