Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. While there is no direct evidence that Lipitor affects yoga performance, there are some potential side effects that could indirectly impact one's ability to perform yoga.

One study found that statin drugs, including Lipitor, can cause muscle pain and weakness, which could make it difficult to perform physical activities such as yoga [2]. Another study found that statin use was associated with decreased physical activity levels, which could also impact yoga performance [3].

It is important to note that not everyone who takes Lipitor will experience these side effects, and some people may be able to continue their yoga practice without any issues. However, if you are experiencing muscle pain or weakness while taking Lipitor, it is important to talk to your doctor to determine the best course of action.

In summary, while there is no direct evidence that Lipitor affects yoga performance, its potential side effects of muscle pain and weakness could indirectly impact one's ability to perform yoga. It is important to talk to your doctor if you are experiencing any side effects while taking Lipitor.
