Lipitor is a brand name for the drug atorvastatin, which is a type of medication known as a statin that is used to lower cholesterol levels in the blood [1]. According to ConsumerLab, there is no evidence to suggest that protein supplements interact negatively with statins like Lipitor [2]. However, it is important to note that some types of protein supplements, such as whey protein, can increase cholesterol levels in some people [2]. Therefore, it is recommended to consult with a healthcare professional before taking any supplements or making any changes to medication regimens.

A study published in the Journal of Clinical Lipidology also found that combining statins with protein supplements did not result in any significant changes in cholesterol levels or muscle damage markers [3]. However, the study was conducted on a small sample size and more research is needed to confirm these findings.

In summary, there is currently no evidence to suggest that taking protein supplements with Lipitor is harmful. However, it is important to consult with a healthcare professional before making any changes to medication regimens or taking any supplements. Additionally, some types of protein supplements may increase cholesterol levels in some people, so it is important to monitor cholesterol levels regularly [2].
