Lipitor (atorvastatin) is a prescription medication that is used to lower cholesterol levels in the blood. According to the National Health Service (NHS) [2], there are several supplements that are safe to take with Lipitor. These include:

1. Calcium and Vitamin D: Lipitor can cause a decrease in calcium levels in the blood, so taking a calcium and vitamin D supplement can help prevent this.

2. Omega-3 fatty acids: These supplements can help reduce inflammation and lower triglyceride levels in the blood.

3. Coenzyme Q10 (CoQ10): Lipitor can lower the levels of CoQ10 in the body, so taking a supplement can help prevent this.

However, there are some supplements that should be avoided when taking Lipitor. According to ConsumerLab [3], the following supplements should be avoided:

1. Red yeast rice: This supplement contains a compound that is similar to the active ingredient in Lipitor and can increase the risk of side effects.

2. St. John's Wort: This supplement can reduce the effectiveness of Lipitor and increase the risk of side effects.

3. Grapefruit juice: Drinking grapefruit juice can increase the levels of Lipitor in the blood and increase the risk of side effects.

It is important to talk to your doctor before taking any supplements with Lipitor to ensure that they are safe and will not interact with the medication.
