Based on the available information, there is no direct evidence that Lipitor, a medication used to treat high cholesterol, impacts protein digestion. Lipitor is a brand name for the drug atorvastatin, which is a type of statin that works by blocking a specific enzyme in the body (HMG-CoA reductase) that is needed in the production of cholesterol [1].

However, one study found that simvastatin, another type of statin, may affect the expression of genes involved in protein digestion in the intestine [3]. The study, which was conducted on rats, found that simvastatin altered the expression of genes related to protein digestion and absorption in the small intestine [3]. However, it is important to note that this study did not investigate the effects of Lipitor specifically, and further research is needed to determine if Lipitor has similar effects on protein digestion.

Additionally, it is worth noting that Lipitor can affect the absorption of certain nutrients, such as coenzyme Q10, which is a nutrient that plays a role in energy production and antioxidant defense [2]. However, this effect is not directly related to protein digestion.

In summary, based on the available information, there is no direct evidence that Lipitor impacts protein digestion. However, one study suggests that other types of statins, such as simvastatin, may affect the expression of genes involved in protein digestion in the intestine [3]. Further research is needed to determine if Lipitor has similar effects on protein digestion.
