Lipitor is a medication used to treat high cholesterol levels and reduce the risk of heart disease [1]. According to a study published in the Journal of Clinical Lipidology, statins like Lipitor have been associated with muscle-related side effects, including muscle pain, weakness, and cramps [2]. However, there is no direct evidence that suggests that Lipitor can affect flexibility during yoga.

It is essential to note that muscle-related side effects of statins are rare and occur in less than 5% of patients [2]. Moreover, the severity of these side effects is generally mild to moderate and resolves on its own within a few weeks or months after stopping the medication [2]. Therefore, it is unlikely that Lipitor would have a significant impact on flexibility during yoga.

In summary, while Lipitor has been associated with muscle-related side effects, including pain, weakness, and cramps, there is no direct evidence that suggests that it can affect flexibility during yoga. It is crucial to talk to a healthcare provider if you experience any muscle-related side effects while taking Lipitor or any other medication.
