There is no evidence to suggest that Lipitor (atorvastatin) affects the absorption of vitamin C. According to the Drug Patent Watch [1], Lipitor is a medication that is used to lower cholesterol levels in the body. While the medication can have side effects, such as muscle pain and weakness, there is no mention of it affecting the absorption of vitamin C.

ConsumerLab [2] also confirms that there is no significant interaction between statins, such as Lipitor, and vitamin C. However, it is important to note that statins can interact with other supplements and medications. For example, taking statins with grapefruit juice can increase the risk of side effects. Therefore, it is always important to speak with a healthcare provider before taking any new supplements or medications, including vitamin C.

A study published in the Journal of Pharmacy and Pharmacology [3] examined the effects of atorvastatin on the absorption of vitamins A and E. The study found that atorvastatin did not significantly affect the absorption of either vitamin. While this study did not specifically examine the absorption of vitamin C, it does suggest that atorvastatin is unlikely to interfere with the absorption of vitamins.

In conclusion, based on the provided sources, there is no evidence to suggest that Lipitor affects the absorption of vitamin C. However, it is always important to speak with a healthcare provider before taking any new supplements or medications, including vitamin C, to ensure that there are no potential interactions or adverse effects.
