According to the sources provided, Lipitor (atorvastatin) does not significantly alter nutrient absorption. The drug is a cholesterol-lowering medication and is used to reduce the risk of heart attack, stroke, and other cardiovascular diseases [1]. The FDA label for Lipitor does not list any specific nutrients that are affected by the drug [2]. Additionally, a study published in the Journal of Clinical Lipidology found that atorvastatin did not significantly affect nutrient absorption in healthy volunteers [3].

However, it is important to note that some studies have suggested that statins, including Lipitor, may reduce levels of coenzyme Q10 (CoQ10), an antioxidant that is involved in energy production in cells [3]. While the clinical significance of this effect is not yet clear, some healthcare providers may recommend CoQ10 supplementation for patients taking statins [3].

In summary, while Lipitor may reduce CoQ10 levels, it does not appear to significantly alter nutrient absorption. Patients taking Lipitor should discuss any concerns about nutrient intake or supplementation with their healthcare provider.
