After reviewing the sources provided, there is no evidence to suggest that Lipitor affects the absorption of skim milk. Lipitor is a medication used to lower cholesterol levels in the blood [1]. Skim milk is a good source of vitamin D, calcium, and other nutrients [3]. The absorption of these nutrients is not affected by Lipitor. However, it is important to note that Lipitor can interact with other medications, so it is always recommended to speak with a healthcare provider before taking any new medication or supplement [2].

In conclusion, there is no evidence to suggest that Lipitor affects the absorption of skim milk. While skim milk is a good source of nutrients, it is always important to consult with a healthcare provider before making any changes to your diet or medication regimen.
