Vitamin E is in the forefront of the nutrition-based health revolution.
The fat-soluble vitamins collectively are proven to fight heart disease and cancer. Chronic deficiencies can cause serious problems ranging from senility to reduction in immunity. Fruits and vegetables are an important part of the US diet. In sufficient servings, they contain all of the vitamin A that the body needs to prevent deficiencies and aid long-term health. Everyone in the US achieves the RDA of 1000 micrograms and studies show that there is no benefit from taking Vitamin A or its precursor, beta-carotene, as supplements.
