Lipitor (atorvastatin) is a medication used to lower cholesterol levels and reduce the risk of heart disease. When it comes to mixing Lipitor with supplements, caution is advised as some supplements can interact with Lipitor and cause side effects.

According to Drug Patent Watch [1], there are no known drug interactions between Lipitor and supplements. However, it is still important to consult with a healthcare provider before taking any supplements with Lipitor.

SingleCare [2] suggests that grapefruit and grapefruit juice should be avoided when taking Lipitor as they can increase the risk of side effects such as muscle pain and liver damage. Other supplements that may interact with Lipitor include St. John's Wort, red yeast rice, and coenzyme Q10.

ConsumerLab [3] recommends avoiding high doses of vitamin D and vitamin K supplements when taking Lipitor as they can interfere with the medication's effectiveness. Additionally, it is important to avoid taking supplements that contain niacin or fiber without consulting with a healthcare provider as they can also interact with Lipitor.

In conclusion, while there are no known drug interactions between Lipitor and supplements, caution is still advised. Grapefruit and grapefruit juice should be avoided, and it is important to consult with a healthcare provider before taking any supplements with Lipitor. Some supplements, such as St. John's Wort, red yeast rice, coenzyme Q10, high doses of vitamin D and vitamin K supplements, niacin, and fiber, may interact with Lipitor and cause side effects.
