[The biological activity of vitamin E]. [Article in Japanese] Kijima S(1). 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.

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. Synthetic vitamin E is racemic mixture containing all the eight isomers of alpha-tocopherol (all racemic) in approximately equal amounts, so it has approximately half of the biological activity of natural vitamin E. Fractionated forms. The most-common fractionated forms are: natural mixed tocopherols and high d-gamma-tocopherol. Alpha-tocopherol Vitamin E can be found in different forms known as tocopherols or tocotrienols.
