Alpha-tocopherol is the primary form of vitamin E that is preferentially used by the human body to meet appropriate dietary requirements. In particular, the RRR-alpha-tocopherol (or sometimes called the d-alpha-tocopherol stereoisomer) stereoisomer is considered the natural formation of alpha-tocopherol and generally exhibits the greatest bioavailability out of all of the alpha-tocopherol stereoisomers. Moreover, manufacturers typically convert the phenol component of the vitamin to esters using acetic or succinic acid, making a compound such as alpha-tocopherol succinate more stable and easier to use in vitamin supplements [A32956, A32957]. Alpha-tocopherol succinate is subsequently most commonly indicated for dietary supplementation in individuals who may demonstrate a genuine deficiency in vitamin E. Vitamin E itself is naturally found in various foods, added to others, or used in commercially available products as a dietary supplement. The recommended dietary allowances (RDAs) for vitamin E alpha-tocopherol are: males = 4 mg (6 IU) females = 4 mg (6 IU) in ages 0-6 months, males = 5 mg (7.5 IU) females = 5 mg (7.5 IU) in ages 7-12 months, males = 6 mg (9 IU) females = 6 mg (9 IU) in ages 1-3 years, males = 7 mg (10.4 IU) females = 7 mg (10.4 IU) in ages 4-8 years, males = 11 mg (16.4 IU) females = 11 mg (16.4 IU) in ages 9-13 years, males = 15 mg (22.4 IU) females = 15 mg (22.4 IU) pregnancy = 15 mg (22.4 IU) lactation = 19 mg (28.4 IU) in ages 14+ years [L2120]. Most individuals obtain adequate vitamin E intake from their diets; genuine vitamin E deficiency is considered to be rare. Nevertheless, vitamin E is known to be a fat-soluble antioxidant that has the capability to neutralize endogenous free radicals. This biologic action of vitamin E consequently continues to generate ongoing interest and study in whether or not its antioxidant abilities may be used to help assist in preventing or treating a number of different conditions like cardiovascular disease, ocular conditions, diabetes, cancer and more. At the moment, however, there exists a lack of formal data and evidence to support any such additional indications for vitamin E use. Moreover, although it is generally believed that alpha-tocopherol succinate would naturally demonstrate such general vitamin E-tocopherol pharmacodynamics after undergoing a logical de-esterification in the gut [A32956, A32957], there is ongoing research that proposes that the alpha-tocopherol succinate compound itself is capable of eliciting anti-cancer [L2699, A32959] and inflammation mediation [A32958] activities that are unique from the alpha-tocopherol form and other alpha-tocopherol esters [L2699, A32958, A32959].
