Based on the information provided, there are potential risks when mixing Lipitor, a medication used to treat high cholesterol, with certain supplements. However, the specific risks are not detailed in the sources.

It is important to note that Lipitor, the brand name for the drug atorvastatin, can interact with various substances, including herbal supplements [1][3]. The Mayo Clinic states that "taking herbal supplements can be beneficial, but it's important to discuss any supplements you're taking or thinking about taking with your health care provider" [2]. This is because some supplements can have potentially harmful interactions with medications like Lipitor.

Furthermore, DrugPatentWatch.com lists potential interactions for Lipitor, but does not provide specific information on the risks of mixing Lipitor with supplements [1]. MedicalNewsToday provides a list of drugs that can interact with Lipitor, but again, does not specify the risks of mixing Lipitor with supplements [3].

Therefore, it is crucial to consult with a healthcare provider before mixing Lipitor with any supplements to ensure there are no adverse interactions.
