Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], there are no known drug interactions with atorvastatin and supplements. However, it is important to note that some supplements may affect the effectiveness of the medication or cause adverse effects. ConsumerLab [2] recommends avoiding supplements that contain large amounts of niacin or antioxidants such as vitamin E and beta-carotene while taking statins, including atorvastatin. These supplements may interfere with the medication's ability to lower cholesterol levels or increase the risk of side effects. Additionally, SingleCare [3] advises avoiding grapefruit and grapefruit juice while taking atorvastatin, as they can increase the risk of side effects. It is always important to talk to a healthcare provider before starting any new supplements or medications to ensure they are safe and effective for an individual's specific needs.
