Lipitor is a medication that is commonly used to lower cholesterol levels. According to the sources provided, there are several vitamin supplements that may interact with Lipitor.

One of the sources [2] mentions that taking vitamin D supplements along with Lipitor may increase the risk of muscle pain or weakness, which is a common side effect of Lipitor. This is because both vitamin D and Lipitor can affect the way that the body processes certain enzymes that are involved in muscle function.

Another source [3] mentions that taking high doses of vitamin E supplements along with Lipitor may also increase the risk of muscle pain or weakness. This is because vitamin E can act as an antioxidant and may interfere with the way that Lipitor works in the body.

Additionally, the same source [3] mentions that taking large amounts of niacin (vitamin B3) supplements along with Lipitor may increase the risk of liver damage. This is because both niacin and Lipitor can affect liver function and may cause liver enzymes to become elevated.

It is important to note that while these interactions are possible, they may not occur in every individual who takes Lipitor and vitamin supplements. It is always a good idea to talk to a healthcare provider before starting any new medications or supplements to ensure that there are no potential interactions or side effects.
