In addition, vitamin E plays an important role in the prevention of cardiovascular disease. Vitamin E is one of the main antioxidants found in cholesterol particles and helps prevent free radicals from oxidizing cholesterol. Only after it has been oxidized is cholesterol able to adhere to blood vessel walls and initiate the process of atherosclerosis, which can lead to blocked arteries, heart attack, or stroke. Getting plenty of vitamin E can significantly reduce the risk of developing atherosclerosis. In fact, studies show that people who get a good amount of vitamin E are at a much lower risk of dying of a heart attack than people whose dietary intake of vitamin E is marginal or inadequate.
