It was found that at an antioxidant concentration of 0.020 per cent a best protection of the biologic vitamin E activity was provided. The rapid inactivation of vitamin E at a level of santoquin lower than 0.016 per cent was associated with the intense deposition of products of the final oxidation when fats turned rancid.

Even though there are 8 forms of vitamin E, the most biologically active form of the vitamin is called alpha-tocopherol. Alpha-tocopherol is considered the most active natural form because it is the preferred form of vitamin E transported and used by the liver.

Author information: (1)Department of Research and Development, Eisai Co. Ltd. The relative biopotency of alpha-(RRR(d)-, 2-ambo (dl)-and all-rac (dl)), beta-, gamma- and delta-tocopherol, tocotrienol homologues and tocopherol derivatives are summarized in the tables. Although vitamin E has been known as an essential nutrient for reproduction since 1922, we are far from understanding the mechanisms of its physiological functions. Vitamin E is the term for a group of tocopherols and tocotrienols, of which alpha-tocopherol has the highest biological activity. Vitamin E may have various roles as a vitamin. Many biological functions have been postulated, including a role as a fat-soluble antioxidant. In this role, vitamin E acts as a radical scavenger, delivering a hydrogen (H) atom to free radicals.
