Alpha-tocopherol synthetic (Tocopherol, Alpha-tocopherol synthetic, vhitamini E, E307) ndeye antioxidant inodzivirira masero kubva mukukuvadzwa nekuderedza oxidation ye lipids (mafuta) uye kuumbwa kwemahara radicals.
Alpha-tocopherol inozivikanwa netsika seyakanyanya antioxidant mumuviri wemunhu. Chiyero chevhitamini E chiitiko muzvikamu zvepasi rose (IU) chaive pamusoro pekuwedzera kwekubereka nekuda kwekudzivirira kwepasipo pakaitika mumakonzo ane pamuviri kana uchitora alpha-tocopherol. Inowedzera zvakasununguka neinenge 150% yezvinoitika mumuviri waamai panguva yekuzvitakura mumadzimai.
1 IU yevhitamini E inotsanangurwa seyakaenzana 0.667 mamirigiramu eRRR-alpha-tocopherol (yaimbonzi d-alpha-tocopherol kana 1 milligram yea-rac-alpha-tocopheryl acetate (yekutengesa inonzi dl-alpha-tocopheryl acetate, iyo yekutanga d, l-synthetic molecular compound, inonyatsodaidzwa kuti 2-ambo-alpha-tocopherol, haisisiri kugadzirwa).
