September is National Cholesterol Education Month, so it’s the perfect time to educate yourself about the dangers of high cholesterol and the best options for managing your cholesterol. High cholesterol runs rampant in the U.S., and it’s linked with many of the country’s leading causes of death. Take our quiz to learn about high cholesterol and ways to protect yourself from this dangerous condition.
