Based on the available information, there is no evidence to suggest that protein absorption is altered by taking Lipitor, also known as atorvastatin.
The first source, a drug patent watch website, does not provide any information about the effects of Lipitor on protein absorption [${1}](https://www.drugpatentwatch.com/p/tradename/PROTEIN). The second source, a study published in the NCBI database, focuses on the effects of atorvastatin on skeletal muscle mitochondria and insulin sensitivity, but it does not mention anything about protein absorption [${2}](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5516053/). The third source, an article published in the Circulation Research journal, discusses the effects of atorvastatin on vascular smooth muscle cell proliferation and migration, but again, it does not mention protein absorption [${3}](https://www.ahajournals.org/doi/full/10.1161/CIRCRESAHA.118.312782).
It is important to note that Lipitor is a medication used to lower cholesterol levels and it is not related to protein absorption. Any changes in protein absorption would be more likely due to diet or other health conditions rather than taking Lipitor.
In conclusion, based on the available information, there is no evidence to suggest that protein absorption is altered by taking Lipitor. If you have any concerns about protein absorption or any other aspect of your health, it is always best to consult with a healthcare professional.
