Based on the available information, there is no direct evidence suggesting that Lipitor, a medication commonly used to treat high cholesterol, impacts protein absorption.

The first source, drugpatentwatch.com, provides information about Lipitor's patent but does not include details about its side effects and protein absorption. The second source, a study published in the Journal of Clinical Lipidology and available on ncbi.nlm.nih.gov, discusses the effects of Lipitor (atorvastatin) on muscle metabolism but does not mention protein absorption. The third source, an article from Circulation Research, discusses the effects of atorvastatin on skeletal muscle mitochondria but does not mention protein absorption.

However, it is important to note that medications can potentially impact nutrient absorption indirectly. For instance, certain medications can affect gut health or digestion, which in turn could influence nutrient absorption. However, the available information does not provide specifics on how Lipitor might impact protein absorption.

In conclusion, while Lipitor has various side effects, there is no direct evidence to suggest that it impacts protein absorption. If you have concerns about how Lipitor or any other medication might be affecting your nutrient absorption, it is best to consult with a healthcare provider.
