Vitamin E

Vitamin E is a fat-soluble vitamin found in many foods, fats, and oils. It is also an antioxidant, a substance that may help prevent damage to the body's cells. Antioxidants may provide protection against serious diseases including heart disease and cancer.

Vitamin E is also important in helping your body make red blood cells, and it helps the body use vitamin K.

People who cannot absorb fat properly may develop vitamin E deficiency. Symptoms of serious vitamin E deficiency include:

  • Muscle weakness
  • Loss of muscle mass
  • Abnormal eye movements
  • Vision problems
  • Unsteady walking

Long-term deficiency may also cause liver and kidney problems. Although most people in the United States are not seriously deficient in vitamin E, many people may have slightly low levels.
