Lipitor is a brand name for the drug atorvastatin, which is a type of medication known as a statin. Statins are commonly prescribed to lower cholesterol levels and reduce the risk of heart disease [1]. According to the drug label provided by the FDA, there is no indication that Lipitor hinders protein absorption [3]. However, the label does mention that some patients taking Lipitor may experience gastrointestinal symptoms such as constipation, flatulence, and dyspepsia [3]. These symptoms may affect digestion and nutrient absorption, but there is no specific mention of protein absorption being affected by Lipitor [3].

A study published in the National Library of Medicine also did not find any evidence that statins like Lipitor affect protein absorption [2]. The study did note that some patients taking statins may experience gastrointestinal side effects, but again, there was no specific mention of protein absorption being affected [2].

In conclusion, there is no evidence to suggest that Lipitor hinders protein absorption. While some patients taking Lipitor may experience gastrointestinal symptoms that could potentially affect nutrient absorption, there is no specific indication that protein absorption is affected by this medication [2][3].
