Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood [1]. According to the sources provided, there is evidence that suggests that taking Lipitor can affect the absorption of certain vitamins, specifically vitamin D.

Vitamin D is a crucial vitamin that helps the body absorb calcium and maintain healthy bones [2]. However, research has shown that taking Lipitor can decrease the absorption of vitamin D [3]. This is because Lipitor can interfere with the body's ability to synthesize vitamin D from sunlight exposure, which is the primary way that the body produces vitamin D [3].

While Lipitor may affect vitamin D absorption, it is important to note that this does not mean that everyone who takes Lipitor will experience vitamin D deficiency. However, individuals who are already at risk for vitamin D deficiency, such as those who live in areas with limited sunlight exposure or who have darker skin, may be more susceptible to this side effect [2].

If you are taking Lipitor and are concerned about your vitamin D levels, it is recommended that you speak with your healthcare provider. They may recommend vitamin D supplements or suggest regular monitoring of your vitamin D levels to ensure that they remain within a healthy range [2].

In conclusion, Lipitor may affect the absorption of vitamin D, which is an essential vitamin for maintaining healthy bones. While not everyone who takes Lipitor will experience this side effect, it is important to speak with your healthcare provider if you are concerned about your vitamin D levels.
