Pankhani ya akatswiri azakudya,vitamini Eali ngati maverick "mutu wa mkondo." Ambirivitaminizizolowezi zimagwira ntchito ngati coenzyme muzochitika zamakina, kusewera gawo lothandizira, ndipo vitamini E ndi yapadera, yokhala ndi mphamvu zake zolimba kuteteza thanzi la munthu. Vitamini E ndi m'gulumafuta osungunukavitamini banja ndipo ndi lochokera kwa benzodihydropyrane ndi ofanana dongosolo ndi kwachilengedwenso ntchito, makamaka kuphatikizapo tocopherol ndi tocotrienol. Gulu lirilonse lagawidwa m'magulu anayi, α, β, γ ndi δ, malingana ndi kusiyana kwa malo a methyl pa mphete ya benzopyrane, mitundu yonse ya 8, ndipo ma isomerswa ali ndi antioxidant mphamvu. Ma radicals aulere ndi gulu la mamolekyu osakhazikika okhala ndi ma reactivity apamwamba kwambiri omwe amapangidwa panthawi ya metabolism. Kuwala kwa ultraviolet, kuipitsidwa kwa chilengedwe ndi zinthu zina zakunja zingapangitse kupanga ma radicals aulere, ndipo mitochondria ndi malo opangira ma free radicals pomwe ma cell amachita aerobic metabolism kuti apereke mphamvu. Ma radicals aulere ochulukirapo amayambitsa kupsinjika kwa okosijeni, komwe kumawononga ma macromolecules monga lipids, mapuloteni ndi DNA mkati mwa maselo, zomwe zimapangitsa kuwonongeka kwa okosijeni. Pa nthawi yovuta, vitamini E imadalira phenolic hydroxyl yake kuti apereke maatomu a haidrojeni kuti agwirizane ndi ma radicals aulere, kuchepetsa ma radicals aulere, kusokoneza ma chain oxidative chain reaction, motero kuteteza maselo.

Kusungunuka kwamafuta kwa vitamini E kumapangitsa kuti azigawika bwino m'malo okhala ndi lipids, monga ma membrane am' cell ndi lipoprotein. Pamalo awa, imalepheretsa kwambiri lipid peroxidation. Pamene ma free radicals amaukira mafuta a polyunsaturatedzidulo, kuyambitsa lipid peroxidation chain reaction yomwe imawononga ma cell membranes ndi lipoproteins, vitamini E imatha kuyimitsa zomwe zimachitika panthawi yoyambira ndi kufalitsa, kuteteza lipids m'matumbo, magazi, minyewa ndi ma cell. Mu mtima dongosolo,vitamini Eamachepetsa kupanga oxidized otsika osalimba lipoprotein kudzera antioxidant kwenikweni, amachepetsa kuwonongeka kwa mtima endothelial maselo, ndiyeno linalake ndipo tikulephera mapangidwe ndi chitukuko cha atherosclerotic zolengeza. Panthawi imodzimodziyo, vitamini E imathanso kuyendetsa kuchulukana ndi kusamuka kwa mitsempha yosalala ya mitsempha ya mitsempha kuti ikhale yokhazikika komanso yokhazikika ya mitsempha ya magazi. Vitamini E amathandizanso kuti chitetezo cha mthupi chitetezeke. Zimalimbikitsa kufalikira ndi kusiyanitsa kwa maselo a chitetezo cha mthupi monga T ndi B lymphocytes, kumawonjezera kugwirizana pakati pa maselo, ndikuwonjezera chitetezo cha mthupi. Panthawi imodzimodziyo, imagwira nawo ntchito yoyendetsera kayendetsedwe ka chitetezo cha mthupi, imakhudza katulutsidwe ndi kufotokoza kwa ma cytokines, ndikuyendetsa chitetezo cha mthupi. Magwero achilengedwe a vitamini E ndi mafuta a masamba, mtedza, mbewu, ndi masamba obiriwira. Mwa magwerowa, mafuta a masamba ndi olemera kwambiri mu vitamini E, makamaka mu mawonekedwe a alpha-tocopherol. Kuonjezera apo, pali multivitamin E zowonjezera pamsika, kuphatikizapo softgel, mapiritsi otsekemera ndi mafuta odzola, omwe ali oyenera zosowa za magulu osiyanasiyana a anthu. Kutengera kuchuluka kwazakudya zopatsa thanzi, kuchuluka kwa vitamini E kwa akulu ndi 15 mg patsiku (kuyezedwa muzofanana za alpha-tocopherol). Komabe, kafukufuku weniweni wa kafukufuku amasonyeza kuti pafupifupi kuchuluka kwa vitamini E omwe amadya ndi akuluakulu kudzera muzakudya zawo za tsiku ndi tsiku nthawi zambiri amakhala osachepera 10 mg. Kafukufuku wina wasonyeza kuti mu adjuvant mankhwala a matenda ena monga kuchedwetsa kukalamba ndi kusintha chidziwitso kuwonongeka kwachidziwitso, kuwonjezera 200-800 mg wa vitamini E tsiku lililonse kungakhale ndi zotsatira zina. Kawirikawiri, vitamini E wapakamwa ndi wotetezeka, koma kudya kwambiri kwa nthawi yaitali (kuposa 1,000 mg patsiku) kungapangitse mwayi wa zovuta monga kutayika kwa magazi. Chifukwa chake, mukamagwiritsa ntchito zowonjezera za vitamini E, ndikofunikira kutsatira upangiri wa akatswiri kuti muwonetsetse chitetezo ndi kulingalira kwa chowonjezeracho.
