Vitamin E

Home >> Blog >> Reference >> Vitamins >> Vitamin E

General Description:

  • fat-soluble vitamin
  • main function is as an antioxidant
  • the correct units for vitamin E are milligrams of alpha-tocopherol equivalents (alpha TE)
  • dl-alpha-tocopherol is a synthetic form of vitamin E
  • d-alpha-tocopherol is the natural form which has been shown to raise serum vitamin E levels 40% higher and the RBC levels 300% higher than the synthetic form

Actions:

  • promising substance in the treatment and prevention of cancer and in the treatment of PMS
  • helps prevent blood clots
  • plays a role in the metabolism of polyunsaturated fats, the kind that help lower blood cholesterol and prevent heart disease
  • acts as an antioxidant preventing certain harmless chemicals in the body from becoming harmful ones
  • an antioxidant also prevents a benign substance from being oxidized into a harmful one that contributes to the cancer process
  • vitamin E may benefit those with benign breast lumps and PMS
  • glutathione protects cells by surface cell membranes whereas vitamin E is located inside cell membranes, where the lipid peroxidation occurs
  • vitamin E breaks the reaction by absorbing the free radicals to form tocopherol and tocopheroxyl radicals
  • breaking the chain quickly uses up vitamin E stores
  • however, vitamin C neutralizes tocopheroxyl free radicals and regenerates vitamin E again
  • Se helps both glutathione and vitamin E, as it forms what is called the active site where glutathione destroys peroxide radicals
  • the vitamin E content of lymphocytes and neutrophils is 10-20 times that of RBCs indicating its importance to the immune system
  • vitamin E also reduces the damage caused by the immune system itself
  • oxygenates the tissues and reduces the need for oxygen intake
  • effective as a vasodilator
  • prevents scar tissue formation
  • effective antithrombin and a natural anti-coagulant
  • essential for healthy function of reproductive glands
  • good for: heart disease, asthma, phlebitis, arthritis, burns, angina, emphysema, leg ulcers, restless legs, varicose veins, hypoglycemia etc.
  • improves glycogen storage in the muscles
  • used successfully in prevention and treatment of reproductive disorders, miscarriages, male and female infertility, still births, and menopausal and menstrual disorders

Deficiency:

  • total vitamin E intake from food is unlikely to exceed 20 IU/day
  • the requirement for vitamin E for an individual depends on the levels of fatty acids in his tissue that can suffer oxidation, and the levels of free radicals he generates
  • deficiency reduces bodily levels of zinc because the two nutrients interact to protect the membranes against damage by free radicals (lipid peroxidation)
  • when there is not sufficient vitamin E, the body compromises by using more zinc, and this can deplete zinc stores and thus increase bodily copper levels
  • symptoms: cardiovascular disease, may cause degeneration of the epithelial and germinal cells of the testicles and lead to loss of sexual potency
  • prolonged deficiency may cause reproductive disorders, abortions, miscarriges, male or female sterility, muscular disorders and increased fragility of RBCs

Interactions and Toxicity:

  • vitamin E prolongs the amount of time required for necessary clotting of the blood which can lead to internal bleeding
  • vitamin E, when initially taken in large doses, improves the tone of the heart muscle, and could lead to an increase in blood pressure in susceptible individuals
  • excess EFAs can deplete the body of vitamin E
  • known antagonists of vitamin E: inorganic iron, estrogenic drugs, chlorine or chlorinated water

Sources:

  • unrefined cold-pressed, crude vegetable oils especially wheat germ and soybean oil
  • all whole raw or sprouted seeds, nuts, and grains
  • green-leafy vegetables and eggs
  • wheat germ must be less than 1 week old unless frozen
