Lipitor is a prescription medication used to lower cholesterol levels in the body. According to Drug Patent Watch [1], Lipitor's patent expired in 2011, which means that other companies can produce generic versions of the drug. However, it is essential to consult with a healthcare professional before taking any natural supplements that may interact with Lipitor.

CardioSmart [2] suggests that some natural supplements may complement Lipitor in reducing cholesterol levels. These supplements include:

1. Plant sterols and stanols: These substances occur naturally in plants and are similar in structure to cholesterol. They work by blocking the absorption of cholesterol in the intestine.

2. Psyllium: This is a type of soluble fiber that can help lower cholesterol levels by binding to bile acids in the intestine.

3. Niacin: This is a B vitamin that can help raise HDL (good) cholesterol levels and lower LDL (bad) cholesterol levels.

4. Red yeast rice: This is a type of fermented rice that contains a compound called monacolin K, which is similar to the active ingredient in statins. It can help lower LDL cholesterol levels.

However, it is essential to note that natural supplements can have side effects and may interact with other medications. Therefore, it is crucial to talk to a healthcare professional before taking any natural supplements to complement Lipitor.

Mayo Clinic [3] advises that natural supplements are not regulated by the FDA, and their quality, purity, and potency may vary. It is essential to research the supplement and the manufacturer before taking it. Additionally, some supplements may have adverse effects, and it is crucial to stop taking them if any adverse effects occur.

In conclusion, some natural supplements may complement Lipitor in reducing cholesterol levels. However, it is essential to consult with a healthcare professional before taking any natural supplements to ensure their safety and effectiveness.
