Interactions
Phytosterols may interact with some drugs, including:
Statins, or cholesterol-lowering medications, include atorvastatin (Lipitor) and simvastatin (Zocor).
medications for high blood pressure, such as ACE inhibitors
medications that suppress the immune system, such as cyclosporine (Neoral, Sandimmune)
Consult your doctor about any medications you are currently taking prior to taking phytosterols.
Phytosterols may obstruct the absorption of fat-soluble vitamins like vitamin A, vitamin D, vitamin E, and vitamin K. This is an important point to remember. Take a fat-soluble vitamin supplement, such as a multivitamin, at least two hours before or after taking phytosterols.
Eating a healthy diet and exercising frequently are crucial for maximizing the benefits of phytosterols. If you don't also change other aspects of your lifestyle, phytosterols won't be effective.
