Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], Lipitor is known to have side effects such as muscle pain, weakness, and liver damage. The Mayo Clinic [2] also states that liver damage is a possible side effect of taking Lipitor, although it is rare. It is recommended to monitor liver function while taking this medication.

In regards to supplements, Medical News Today [3] states that some supplements can also cause liver damage. For example, high doses of vitamin A, niacin, and iron can be toxic to the liver. Additionally, herbal supplements such as kava, comfrey, and ephedra have been linked to liver damage.

It is important to note that combining Lipitor with certain supplements may increase the risk of liver damage. Therefore, it is recommended to speak with a healthcare provider before taking any supplements while on Lipitor.

In conclusion, both Lipitor and supplements have the potential to cause liver damage. It is important to monitor liver function while taking Lipitor and to speak with a healthcare provider before taking any supplements.
