Vitamin E is a fat soluble vitamin and a collective name for tocopherols and Vitamin E 1 Canadian Academy of Sports Nutritiontocoteriols. Being famous as the “fertility vitamin”, vitamin E acts as a potent antioxidant. Among the eight isomers of tocopherols, alpha – tocopherol and gamma – tocopherol are the two most common forms.

Functions of Vitamin E:

  1. It acts as a chain – breaking antioxidant and scavenges the pyroxyl radicals.
  2. It inhibits the synthesis of prostaglandins and the activities of protein kinase C and phospholipase A2.
  3. It protects cell membranes, unsaturated fatty acids, adrenal hormones, and LDL cholesterol from oxidation.
  4. It protects the lungs from oxidative damage caused by environmental substances.
  5. It shows anti – inflammatory activity.
  6. It demonstrates anti – coagulating activity.
  7. It may prevent platelet aggregation.
  8. The function and effectiveness of vitamin E is enhanced by vitamin CCo – Enzyme Q10seleniumglutathione, and beta – carotene.

Food Sources and Absorption:

Vitamin E is found in wheat germ oil, safflower oil, seeds, nuts, whole grains, egg yolks, butter, milk, liver, and green leafy vegetables. It is absorbed along with fats and bile salts from the small intestine and then is transported to the liver. The absorption of vitamin E is decreased by chlorine and mineral oils. Estrogens may deplete vitamin E from the body. The absorption of vitamin E from the skin is poor.

Vitamin E is not stored as good and effectively as other fat soluble vitamins. However, small amounts are mainly stored in the fatty tissues and liver. It is also stored in the heart, testicles, adrenal glands, uterine, muscles and pituitary gland.

Athletic Benefits of Vitamin E: Vitamin E 2 Canadian Academy of Sports Nutrition

  1. It may prevent exercise – induced muscle damage.
  2. It has a protective effect against post – exercise rhabdomyolysis (post – exercise myoglobinuria). See “Post – Exercise Rhabdomyolysis” under the section of “Athletic Disorders”.
  3. It may prevent overtraining syndrome.
  4. It speeds up recovery from intense training sessions.
  5. It may boost the production of steroid hormones by the adrenal glands, supporting muscle growth.
  6. Also see “Vitamin E” under the section of “Testosterone Boosters”.
