Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. The drug works by inhibiting the enzyme HMG-CoA reductase, which is responsible for producing cholesterol in the liver [1]. While there is no direct evidence that Lipitor affects vitamin absorption, there are some studies that suggest that it may indirectly impact the absorption of certain vitamins.

One study published in the Journal of Clinical Endocrinology and Metabolism found that statins, including Lipitor, may reduce the absorption of vitamin D in the body [2]. Vitamin D is an essential nutrient that helps the body absorb calcium and maintain healthy bones. The study found that people taking statins had lower levels of vitamin D in their blood compared to those not taking statins. However, the study did not specifically look at the effect of Lipitor on vitamin D absorption.

Another study published in the Journal of the American College of Cardiology found that people taking statins had lower levels of coenzyme Q10 (CoQ10) in their blood [3]. CoQ10 is a vitamin-like substance that plays a role in energy production in the body. The study found that people taking statins had a 22% reduction in CoQ10 levels compared to those not taking statins. However, the study did not specifically look at the effect of Lipitor on CoQ10 levels.

While there is no direct evidence that Lipitor affects vitamin absorption, it is important to talk to your doctor about any concerns you may have about nutrient deficiencies. Your doctor may recommend monitoring your vitamin levels or taking supplements to ensure that you are getting the nutrients your body needs.
