Vitamin E Supplements / Benefits / Facts / Positive Side Effects
Reprinted by permission from Bill Faloon of The Life Extension Foundation

The term vitamin E refers to a family of eight related, lipid-soluble, antioxidant compounds widely distributed in plants.  The tocopherol and tocotrienol subfamilies are each composed of alpha, beta, gamma, and delta vitamers having unique biological positive side effects.  Different ratios of these compounds are found in anatomically different parts of a plant.  For example, the green parts of a plant contain mostly alpha-tocopherol and the seed germ and bran contain mostly tocotrienols.  Along with other nutrients tocopherols and tocotrienols are concentrated in the bran layers of the rye grain, and are only present at low levels in the flour endosperm.  Tocopherols are also present in algae, mint teas, and other food stuff.87-93

When this family of compounds was first discovered and determined to be essential for health, a standardized test for its activity was devised for which the members of the family were rated for their biological activity.  In one test, alpha tocopherol scored highest and was rated 100% with all other sources having lower ratings.  In accordance with this rating, alpha-tocopherol was deemed to be the essential compound and was called vitamin E.  One International Unit (IU) of vitamin E activity is the activity under this rating of one mg of the plant-derived form of alpha-tocopherol.94  Since the original rating method was established, many additional important biological positive side effects of these compounds have been discovered and many nutritional scientists now consider that rating method to be incomplete.

For example, by the original rating, gamma-tocopherol was only 10% to 30% as strong as alpha-tocopherol, yet more recent studies have shown it to be essential for maintaining the health of cell membranes, especially if alpha-tocopherol is being supplemented.  New studies continue to elucidate the unique benefits and positive side effects of individual members of the vitamin E family.  For these and other reasons, the original definition of vitamin E has been enhanced to include all eight family members and the related compounds that convert to them in the body.94

Vitamin E sources are usually produced and made available in esterified form as alpha-tocopheryl acetate or alpha-tocopheryl succinate.  Neither of these forms has any antioxidant activity until converted to alpha-tocopherol in the body.  However, they are much more stable with respect to storage time and temperature than the unesterified forms.  Moreover, while the acetate sources are rapidly activated within the body, activation of the succinate form is slower.  The succinate form appears to access and benefit areas of the tissues that are unavailable to the other forms.  For this reason, there is a tendency to regard alpha-tocopherol succinate as a distinctly different and beneficial compound.  Alpha-tocopherol succinate appears to have longer half-life in the body, and does not interfere with vitamin A or K absorption, side effects free.95-98

Serious vitamin takers prefer cold-water dispersible dry powder vitamin E supplements in the form of alpha-tocopheryl succinate or acetate because the cold-water dispersible sources are efficiently absorbed even when taken on an empty stomach or with a low-fat meal.  The non-cold water dispersible (oil) forms of vitamin E may be poorly absorbed unless taken with several grams of fats or oils.

Cold-water dispersible vitamin E is more efficiently absorbed than some other forms.  Both acetate and succinate vitamin E can come from natural sources.  The importance to the consumer is how well the vitamin E absorbs into the bloodstream.  Cold-water dispersible vitamin E, whether in a succinate or acetate form, always comes in a white dry powder, while non-cold water dispersible natural and synthetic acetate forms of vitamin E are always in a thick brown oil.

One or more members of the vitamin E family may:
  • Maintain cell membrane integrity99-102*
  • Act as a free radical scavenger of lipids103,104*
  • Maintain health105-108*
  • Protect your system109-113*

Warnings Information:

  • For dietary supplement use only,

  • Keep out of reach of children,

  • Do not exceed recommended dosage,

  • If you have a bad reaction or negative side effects, discontinue use immediately,

  • When using natural vitamin E supplements, please inform your physician,

  • If you are pregnant, lactating or have a medical condition, consult your health care professional before using this or any other nutritional sources,

  • If side effects of allergic reaction occurs, discontinue immediately.
