Vitamin E is an important fat-soluble vitamin and antioxidant that helps combat damaging free radicals. It also plays a role in the making of red blood cells and helps your body use vitamin K, the latter of which is important for heart health. Unfortunately, estimates suggest about 6 billion people worldwide are deficient in this basic micronutrient. According to a recent review presented at the World Congress of Public Health Nutrition, more than 90 percent of Americans fail to reach the recommended daily allowance (RDA) of vitamin E. An earlier review published in 2012 found that over 75 percent of Americans and Britons failed to meet minimum RDA levels for vitamin E.
