Kutholakale ngokwemvelo kokudla okunye, i-vitamin E iyaziwa ukuthi idlala indima ebalulekile ekuzivikelweni komzimba kanye nasezinkambisweni ezithile zemithi. Njengoba i-vitamin E i-antioxidant, kucatshangwa ukuthi ilwa nokucindezeleka okwenziwa yi-oxidative ngenxa yama-radicals mahhala (izakhi zamakhemikhali eziboniswe ukulimaza i-DNA).
Sibutsetelo
Njengama-antioxidant, amavithamini e-vitamin E ngokuvamile avame ukuba njengendlela engokwemvelo yokwelapha noma yokuvimbela izifo ezihlukahlukene ezihambisana nokucindezeleka okwenziwe nge-oxidative, njengesifo senhliziyo, ukulahleka komqondo okudala ubudala, isifo se-Alzheimer, nesifo sikashukela.
I-Vitamin E isetshenziselwa ubukhulu bomzimba ebusweni nasemzimbeni futhi iyisithako emikhiqizo yokunakekela isikhumba.
Nakuba i-vitamin E itholakale ngokwemvelo kokudla okuningana , abanye abantu bathatha ukwesekwa ngomzamo wokukhulisa amazinga alo mzimba obalulekile. Abantu abanezifo ezifana nesifo sesibindi noma isifo sikaCrohn bangadinga u-vitamin E ngaphezulu, noma kunjalo abantu abaningi bangakwazi ukuthola ukudla okwanele ngokudla kuphela.
Izinzuzo
Kuze kube manje, izilingo ezinkulu ezempilo ze-vitamin E zithengise imiphumela exubile futhi evame ukudumaza. Ucwaningo oluthile lubonisa ukuthi i-vitamin E ayihlinzeki ngenzuzo enkulu yezempilo futhi inemiphumela emibi ephawulekayo. Isibonelo, izilingo zisho ukuthi i-vitamin E ingakhuphula umdlavuza we-prostate kanye ne-adenoma ekhohlisayo futhi yandise ukufa kwabantu bonke.
Umbiko we-2005 owashicilelwa ku- Annals of Internal Medicine ubuyekeze izivivinyo ezingama-19 (kanye nabantu abangu-135 968) ku-vitamin E futhi bathola ukuthi izithako ze-vitamin E zehlulekile ukunciphisa ingozi yesifo senhliziyo noma umdlavuza.
Ngaphezu kwalokho, abalobi bombiko banqume ukuthi amalungu okutadisha abathola i-placebo aphila isikhathi eside kakhulu uma kuqhathaniswa nalabo abathwala ama-vitamin E amaningi (400IU noma ngaphezulu). Okunye ukuhlaziya kamuva akubonisi imiphumela ye-supplementation ye-vitamin E ekufeni.
Ngakolunye uhlangothi, olunye ucwaningo lubonisa ukuthi izithako ezenziwe nge-vitamin E kanye nokudla okunengi okudla okunamavithamini-E (okufana namafutha wegorosi, ama-almonds, kanye nembewu ye-sunflower) kungasiza ukunciphisa ingozi yezifo ezithile.
Isibonelo, umbiko we-2015 oshicilelwe ku- Public Health Nutrition uhlolisise izifundo ezishicilelwe ngaphambilini mayelana nobuhlobo phakathi kuka-vitamin E kanye ne-cataracts ephathelene nobudala futhi zathola ukuthi ukungenisa ukudla kwe-vitamin E nokudla okungeziwe okubandakanya u-vitamin E kungase kuhlotshaniswe nengozi enciphise ye-cataracts ehlobene neminyaka .
Ucwaningo lubonisa ukuthi i-vitamin E ingase izuze abantu abanezifo ezingenalo utshwala (NAFLD) kanye ne-steatohepatitis engeyona ingcolile (NASH). Isibonelo, umbiko oshicilelwe ku- Hepatology ngo-2015 uhlaziye uvivinyo olushicilelwe ngaphambilini ekusebenziseni u-vitamin E uma kuqhathaniswa nezinye izifo noma indawo ye-placebo kubantu abane-NASH. Abacwaningi bathola ukuthi i-vitamin E ihlehlisiwe ukubola kwe-ballooning ne-steatosis phezu kwe-placebo.
Amafomu
I-Vitamin E ifika ku-capsule (ngokuvamile ebizwa ngokuthi i-softgels), ithebhulethi, noma ifomu elimanzi. Amanye amafutha ahloselwe ukusetshenziselwa ama-topical kuphela, ngakho-ke kubalulekile ukufunda amalebula ngokucophelela.
Izinhlobo ezimbili zamavithamini E-vitamin E yi-d-alpha-tocopherol (ifomu lemvelo) kanye ne-dl-alpha-tocopherol (ifomu yokwenziwa). Abantu badinga iUU ye-synthetic alpha tocopherol kusuka kokudla okunomsoco nokudla okuqinisekisiwe ukuze bathole inani elifanayo lomsoco njengamafomu wemvelo. I-tocopherols ehlanganisiwe nayo iyatholakala.
Okuhlobene: Ukudla Imithombo ye-Vitamin E
Ukusetshenziswa kwezihloko
I-Vitamin E isho ukuthi kuncishiswa ukubonakala kwezibazi kanye nama-stretch mark uma amafutha (kusuka kumikhiqizo yamafutha noma i-gel capsules) esetshenziswa ngokuqondile ebusweni nasesikhumba. Uma isetshenziselwa ubuchwepheshe, kuthiwa kusiza ukunciphisa izibazi ngokufaka isikhumba esikhwameni, ukuvimbela ukuhlanganiswa kwe-collagen, nokwehlisa ukuvuvukala ngesikhathi sesibindi sokuphulukiswa kwesilonda.
Ucwaningo olwengeziwe luyadingeka ngoba ezinye izifundo zibonisa ukuthi angeke zisize ukusheshisa ukuphulukiswa. Isibonelo, isifundo esashicilelwe ku- Dermatologic Surgery sathola ukuthi amafutha e-vitamin E asebenza ngokuqondile esikhumbeni awazange asize ekuthuthukiseni ukubukeka kwezibazi.
Ngaphezu kwalokho, amaphesenti angu-33 abantu abasebenzisa wona ahlakulele ukucasuka kwesikhumba okuvamile okubizwa ngokuthi i-contact dermatitis.
Okuqhamuka uma udla imishanguzo
Ngokusho kwe-NIH, ukuphakama okukhulu kwevithamini E ekwakhekeni kungafaka ingozi yemiphumela emibi kakhulu, njengengozi enkulu yokwehla kwesifo esibi.
Kwezinye izimo, ukuthatha ama-vitamin E ngokwezinga eliphezulu kungabangela imiphumela emibi (kubandakanya ukucwenga, ukuhlanza, ubuhlungu besisu, nokuhuda). Ngaphezu kwalokho, ucwaningo oluthile lubonisa ukuthi izithako ze-vitamin E zingabangela ingozi enkulu yokwehluleka kwenhliziyo nokwanda kwabantu.
I-Vitamin E inganciphisa igazi futhi yandisa ingozi yokuphuma kwegazi. Kungase kusebenzisane nemithi egazini yegazi kanye nezithako, ezifana ne-warfarin, i-garlic, ne-gingko. Akufanele isetshenziswe ngaphakathi kwamasonto amabili okuhlinzwa.
Uma unomdlavuza we-chemotherapy noma i-radiotherapy, thintana ne-oncologist yakho ngaphambi kokuthatha u-vitamin E.
Ucwaningo alutholanga imiphumela emibi ye-vitamin E ekudleni.
Izwi elivela
Uma ucabangela ukusetshenziswa kwamavithamini E okuvimbela noma ukwelashwa kwanoma yiluphi uhlobo lwezempilo, qiniseka ukuthi ubonisane nodokotela wakho ukuze uhlole izingozi nezinzuzo ezingenzeka. Kumele futhi ukhulume nodokotela wakho uma ubona izimpawu zokuntuleka kwe-vitamin E (njengobuthakathaka bemisipha, izinkinga ezibukwayo, nokuqonda okungalungile kokulinganisela).

Ukuziphendulela: Ulwazi oluqukethwe kule sayithi luhloswe ngezinjongo zemfundo kuphela futhi aluthathi iseluleko, ukuxilongwa noma ukwelashwa ngudokotela olayisensi. Akuhloselwe ukumboza zonke izinyathelo zokuqapha, ukusebenzisana kwezidakamizwa, izimo noma imiphumela emibi.
