So, cholesterol is not inherently a harmful compound, but high levels of it in the blood are. Some divide cholesterol into "good" cholesterol (HDL) and bad cholesterol (LDL). When someone has a high level of bad cholesterol in their blood, they become at risk of developing a heart attack. When bad cholesterol becomes oxidized by free radicals, it becomes more likely to burrow into the walls of the arteries. As an antioxidant, Vitamin E can play a major role in preventing the oxidation of cholesterol that leads to LDL cholesterol and an increased risk for the development of heart disease.
