Lipitor, also known as atorvastatin, is a commonly prescribed medication for high cholesterol [1]. While there is no direct evidence that suggests Lipitor affects energy levels during workouts, there are some potential side effects of the medication that may impact physical activity.

One study found that statins, including Lipitor, may cause muscle damage in some individuals, which can lead to muscle weakness and fatigue [2]. This could potentially impact energy levels during workouts. However, the study also notes that the incidence of muscle damage is relatively low and that the benefits of statins in reducing the risk of heart disease outweigh the risks of muscle damage for most patients.

Another study found that statins may decrease the production of coenzyme Q10 (CoQ10), a substance that is important for energy production in cells [3]. This could potentially impact energy levels during workouts, although more research is needed to fully understand the implications of this finding.

Overall, while there is no direct evidence that Lipitor affects energy levels during workouts, there are some potential side effects of the medication that may impact physical activity. Patients who are concerned about their energy levels during workouts should speak with their healthcare provider to discuss any potential risks or concerns.
