Lipitor is a medication used to lower cholesterol levels in the body. According to the sources provided, there are some joint supplements that should be avoided while taking Lipitor.

ConsumerLab [2] advises that individuals taking statins, such as Lipitor, should avoid taking supplements containing high doses of vitamin D and calcium. This is because statins can increase the risk of developing muscle pain and weakness, and taking high doses of vitamin D and calcium supplements may increase this risk further.

Additionally, Drug Patent Watch [1] states that Lipitor should not be taken with supplements containing red yeast rice, as this can increase the risk of developing muscle pain and liver damage.

It is important to note that joint supplements may contain a variety of ingredients, and it is best to consult with a healthcare provider before taking any supplements while on Lipitor. The Mayo Clinic [3] advises that individuals taking Lipitor should inform their healthcare provider of any supplements or medications they are taking to avoid any potential interactions.

In summary, individuals taking Lipitor should avoid joint supplements containing high doses of vitamin D and calcium, as well as supplements containing red yeast rice. It is recommended to consult with a healthcare provider before taking any supplements while on Lipitor.
