Uvithamini D ubuthi buyivelakancane ngokweqile, kepha kwenzeka ngemithamo eyeqile.

Imvamisa ikhula ngokuhamba kwesikhathi, ngoba uvithamini D owengeziwe angakha emzimbeni.

Cishe konke ukweqisa ngokwevithamini D kubangelwa ukuthatha inani eliphakeme lamavithamini D.

Cishe akunakwenzeka ukuthola uvithamini D omningi kakhulu elangeni noma ekudleni.

Le yindatshana eningiliziwe mayelana nobuthi bevithamini D nokuthi ingakanani yayo ethathwa njengeyiningi kakhulu.

Vitamin D Ubuthi - Kwenzeka Kanjani?

Ubuthi buka-Vitamin D busho ukuthi amazinga kavithamini D emzimbeni aphezulu kakhulu kangangokuba adala ingozi.

Kubizwa nangokuthi i-hypervitaminosis D.

Uvithamini D uvithamini oncibilika njengamafutha. Ngokuphikisana namavithamini ancibilikiswa ngamanzi, umzimba awunayo indlela elula yokususa amavithamini ancibilikayo anamafutha.

Ngalesi sizathu, amanani amaningi ngokweqile angakha ngaphakathi komzimba.

Indlela eqondile yokuthola ubuthi bukavithamini D iyinkimbinkimbi futhi ayiqondakali kahle okwamanje.

Kodwa-ke, siyazi ukuthi ifomu elisebenzayo levithamini D lisebenza ngendlela efanayo ne-hormone ye-steroid.

Ihamba ngaphakathi kwamaseli, ibatshele ukuthi bavule noma bacime izakhi zofuzo.

Imvamisa, uvithamini D omningi womzimba ugcinwa, uboshelwe ku-vitamin D ama-receptors noma ama-carrier protein. Uvithamini D omncane “okhululekile” kakhulu uyatholakala (,).

Kodwa-ke, lapho ukudla kukavithamini D kukweqile, amazinga angaba phezulu kakhulu kangangokuthi ayikho indawo esele kuma-receptors noma kuma-carrier protein.

Lokhu kungaholela emazingeni aphakeme kavithamini D "wamahhala" emzimbeni, ongahamba ngaphakathi kwamaseli futhi uqede izinqubo zokubonisa ezithinteka ku-vitamin D.

Enye yezinqubo ezisayinayo ezinkulu ihlobene nokwandisa ukumuncwa kwe-calcium kusuka ohlelweni lokugaya ukudla ().

Ngenxa yalokho, uphawu oluyinhloko lwe-vitamin D ubuthi yi-hypercalcemia - amazinga aphakeme we-calcium egazini (,).

Izinga eliphakeme le-calcium lingadala izimpawu ezahlukahlukene, kanti ne-calcium nayo ingabopha ezinye izicubu ibalimaze. Lokhu kufaka izinso.

Uvithamini D ubuthi ubizwa nangokuthi yi-hypervitaminosis D. Kusho ukuthi amazinga kavithamini D emzimbeni aphezulu kakhulu kangangokuba adala ingozi, okuholela kwi-hypercalcemia nezinye izimpawu.

Izengezo 101: Uvithamini D

Izinga Legazi likaVithamini D: Elifanele Uma liqhathaniswa Nokweqisa

UVitamin D uyi-vitamin ebalulekile, futhi cishe wonke amaseli emzimbeni wakho ane-receptor yawo ().

Ikhiqizwa esikhumbeni lapho ivezwe elangeni.

Imithombo yokudla esemqoka kavithamini D ngamafutha wesibindi senhlanzi nezinhlanzi ezinamafutha.

Kubantu abangakutholi ukukhanya kwelanga okwanele, izithasiselo zikavithamini D zingabalulekile.

UVitamin D ubaluleke kakhulu empilweni yamathambo, futhi uphinde waxhunyaniswa nokusebenza komzimba nokuvikelwa kumdlavuza (, 8).

Imihlahlandlela yamazinga egazi kavithamini D imi kanje (,,,,,):

• Kwanele: 20-30 ng / ml, noma 50-75 nmol / L.
• Umkhawulo ongaphezulu ophephile: 60 ng / ml, noma 150 nmol / L.
• Kuyingozi: Ngaphezulu kwe-150 ng / mL, noma i-375 nmol / L.

Ukudla kukavithamini D kwansuku zonke okungama-1000-4000 IU (ama-micrograms angama-25-100) kufanele kwanele ukuqinisekisa amazinga egazi amahle kubantu abaningi.

Amazinga egazi ebangeni lama-20-30 ng / ml ngokuvamile abhekwa njengokwanele. Umkhawulo ongaphezulu ophephile uthathwa cishe ungama-60 ng / ml, kepha abantu abanezimpawu zobuthi ngokuvamile banamazinga angaphezu kuka-150 ng / ml.

Ingabe uVithamini D Ungakanani?

Njengoba kuncane kakhulu okwaziwayo ukuthi ubuthi bukavithamini D busebenza kanjani, kunzima ukuchaza umkhawulo oqondile wokudla okuphephile noma okunobuthi kukavithamini D ().

Ngokuya nge-Institute of Medicine, ama-4000 IU yizinga eliphezulu eliphephile lokudla ivithamini D nsuku zonke. Kodwa-ke, amanani angafika ku-10,000 IU awakhonjiswanga ukuthi abangela ubuthi kubantu abaphilile (,).

Uvithamini D ubuthi ngokuvamile ubangelwa imithamo eyeqile yamavithamini D, hhayi ngokudla noma ngokuchayeka elangeni (,).

Yize ubuthi bukavithamini D buyisimo esingajwayelekile, ukwanda kwamuva ekusetshenzisweni kokungezelela kungaholela ekwandeni kwamacala abikiwe.

Ukudla kwansuku zonke kusuka ku-40,000-1,000,000 IU (1000-2500 micrograms), inyanga eyodwa kuya ezinyangeni ezimbalwa, kukhonjisiwe ukuthi kubangela ubuthi kubantu (,,,,).

Lezi yizikhathi eziyi-10-25 umkhawulo ophezulu onconyiwe, ngemithamo ephindaphindwayo. Abantu abanobuthi bukavithamini D bavame ukuba namazinga egazi angaphezu kwe-150 ng / ml (375 nmol / L).

Amacala amaningana nawo abangelwe amaphutha ekukhiqizeni, lapho izithako zinamanani aphakeme ka-100-4000 kavithamini D kunalokho okushiwo kuphakheji (,,).

Amazinga egazi kulezi zimo zobuthi abesukela ku-257-620 ng / ml, noma u-644-1549 nmol / L.

Uvithamini D ubuthi uvame ukubuyiselwa emuva, kepha amacala abucayi angagcina ebangele ukwehluleka kwezinso nokubalwa kwemithambo (,).

Umkhawulo ophephile wokudla usethwe ku-4000 IU / ngosuku. Ukudla okuphakathi kwama-40,000-1,000,000 IU / ngosuku (izikhathi eziyi-10-25 umkhawulo ongaphezulu onconyiwe) kuxhunyaniswe nobuthi kubantu.

Izimpawu kanye nokwelashwa kwe-Vitamin D Toxicity

Umphumela omkhulu wobuthi bukavithamini D ukwakhiwa kwe-calcium egazini, ebizwa nge-hypercalcemia ().

Izimpawu zokuqala ze-hypercalcemia zifaka isicanucanu, ukuhlanza, uhudo, ukuqunjelwa nobuthakathaka ().

Ukoma ngokweqile, izinga lokuqonda eliguquliwe, umfutho wegazi ophakeme, ukubalwa kwamashubhu ezinso, ukwehluleka kwezinso noma ukulahleka kokuzwa nakho kungavela (,).

I-Hypercalcemia ebangelwa ukuthatha njalo inani eliphakeme lamavithamini D kungathatha izinyanga ezimbalwa ukuyixazulula. Lokhu kungenxa yokuthi uvithamini D unqwabelana emafutheni omzimba, futhi ukhishelwa egazini kancane ().

Ukwelapha ukudakwa kukavithamini D kufaka phakathi ukugwema ukuvezwa yilanga nokuqeda konke ukudla okunezakhi zokudla kanye nokwengeza i-vitamin D.

Udokotela wakho futhi angalungisa amazinga akho e-calcium ngosawoti owengeziwe kanye noketshezi, imvamisa nge-saline efakwa emithanjeni.

Umphumela omkhulu wobuthi bukavithamini D yi-hypercalcemia, enezimpawu ezibandakanya isicashu, ukuhlanza, ubuthakathaka nokwehluleka kwezinso. Ukwelashwa kufaka ukukhawulela konke ukudla kukavithamini D nokuchayeka elangeni.

Imithamo Emikhulu Ingalimaza, Ngisho Ngaphandle Kwezimpawu Zobuthi

Imithamo emikhulu kavithamini D ingaba yingozi, yize kungahle kungabikho zimpawu ezisheshayo zobuthi.

Uvithamini D akunakwenzeka ukuthi abangele izimpawu ezinzima zobuthi ngokushesha, futhi izimpawu zingathatha izinyanga noma iminyaka ukuthi zivele.

Lesi ngesinye sezizathu esenza kube nzima ukuthola ubuthi bukavithamini D.

Kuke kwaba nemibiko yabantu abathatha imithamo emikhulu kakhulu kavithamini D izinyanga ngaphandle kwezimpawu, kepha ukuhlolwa kwegazi kuveze i-hypercalcemia enamandla kanye nezimpawu zokuhluleka kwezinso ().

Imiphumela eyingozi kavithamini D iyinkimbinkimbi kakhulu. Ukweqiwa okuphezulu kukavithamini D kungadala i-hypercalcemia ngaphandle kwezimpawu zobuthi, kepha futhi kungadala nezimpawu zobuthi ngaphandle kwe-hypercalcemia ().

Ukuze uphephe, akufanele weqe umkhawulo ophezulu we-4,000 IU (100 mcg) ngaphandle kokubonisana nodokotela noma nodokotela wezokudla.

Ubuthi be-Vitamin D buvame ukukhula ngokuhamba kwesikhathi, futhi imiphumela eyingozi inzima kakhulu. Ukweqiwa okukhulu kungadala ukulimala, yize kungekho zimpawu ezibonakalayo.

Ingabe Ukutholwa Kwamanye Amavithamini Ancibilikiswa Amafutha Kuyashintsha Ukubekezelela Uvithamini D?

Kucatshangwe ukuthi amanye amavithamini amabili ancibilikisa amafutha, uvithamini K novithamini A, angadlala indima ebalulekile ku-vitamin D ubuthi.

UVitamin K usiza ukulawula lapho i-calcium iphelela khona emzimbeni, futhi amanani aphezulu kavithamini D angaqeda izitolo zomzimba zikavithamini K (,).

Ukudla okuphezulu kukavithamini A kungasiza ukuvimbela lokhu ukuthi kwenzeke ngokugwema izitolo zikavithamini K.

Esinye isakhi somzimba esingabalulekile yi-magnesium. Ngenye yezakhi ezidingekayo ekuthuthukiseni impilo yethambo (,).

Ukuthatha uvithamini A, uvithamini K kanye nemagnesium ngevithamini D ngakho-ke kungathuthukisa ukusebenza kwamathambo futhi kunciphise namathuba okuba ezinye izicubu zibalwe (,,).

Khumbula ukuthi lokhu kumane kuyizinto zokucabanga, kepha kungahle kube ukuhlakanipha ukuthi uqiniseke ukuthi uthola lezi zakhi zomzimba ezanele uma uzokwengeza nge-vitamin D.

Uma ungeza nge-vitamin D, lapho-ke kungabaluleka futhi ukuqinisekisa ukutholwa okwanele kukavithamini A, uvithamini K kanye ne-magnesium. Lokhu kunganciphisa ubungozi bemiphumela emibi kusuka ku-vitamin D ephezulu.

Thatha Umlayezo Wekhaya

Abantu baphendula ngokwehluke kakhulu kumithamo ephezulu kavithamini D. Ngakho-ke, kunzima ukuhlola ukuthi yimiphi imithamo ephephile futhi engaphephile.

Ubuthi bukaVitamin D bungaba nemiphumela emibi yezempilo, engahle ingaveli kuze kube izinyanga noma ngisho neminyaka ngemuva kokuqala ukuthatha imithamo ephezulu.

Ngokuvamile, akunconywa ukweqa umkhawulo ophezulu wokudla okuphephile, okuyi I-4000 IU (ama-micrograms ayi-100) ngosuku.

Imithamo emikhulu ayixhunyanisiwe nanoma yiziphi izinzuzo ezengeziwe zezempilo, ngakho-ke kungenzeka ingadingeki ngokuphelele.

Ngezinye izikhathi umthamo ophakeme kavithamini D kwesinye isikhathi usetshenziselwa ukwelapha ukusweleka, kepha ngaso sonke isikhathi thintana nodokotela wakho noma nodokotela wezokudla ngaphambi kokuthatha umthamo omkhulu.

Njengakwezinye izinto eziningi kwezondlayo, okuningi akulingani kangcono njalo.
