Lipitor is a medication used to lower cholesterol levels in the body. It is a brand name for the drug atorvastatin, which belongs to a class of drugs called statins [1]. There is limited research on the effects of Lipitor on athletic performance. However, one study published in the Journal of Clinical Lipidology in 2017 examined the impact of statins on physical activity and found that statins did not have a significant effect on exercise performance [3]. Another study published in the Journal of Geriatric Cardiology in 2015 also found that statins did not have a significant effect on exercise performance in older adults [2].

While these studies suggest that Lipitor may not significantly affect athletic performance, it is important to note that every individual may respond differently to the medication. Additionally, it is important to consult with a healthcare provider before starting any new medication, as they can provide personalized recommendations based on an individual's health history and current medications.
