Lipitor is a brand name for atorvastatin, a medication that is used to lower cholesterol levels in the blood. When taking Lipitor, it is essential to be aware of the supplements that can be safely taken with it to avoid any adverse interactions.

According to the NHS [2], it is generally safe to take vitamin supplements, such as vitamin D, with Lipitor. However, it is recommended to avoid taking supplements that contain large amounts of vitamin A, such as fish liver oil, as it can increase the risk of side effects. Additionally, St. John's Wort, a herbal supplement used for depression, should be avoided as it can reduce the effectiveness of Lipitor.

ConsumerLab [3] also advises avoiding grapefruit and grapefruit juice when taking Lipitor, as it can increase the risk of side effects. Similarly, it is recommended to avoid taking supplements containing red yeast rice, as it contains a natural statin that can increase the risk of side effects when taken with Lipitor.

It is always best to consult with a healthcare provider before taking any supplements with Lipitor to ensure that there are no potential interactions. Additionally, it is important to follow the recommended dosage of Lipitor and any supplements taken to avoid any adverse effects.
