Vitamina K<\/strong> \u00ebsht\u00eb nj\u00eb grup vitaminash q\u00eb gjenden n\u00eb disa perime me gjethe jeshile. Vitaminat K1 (fitonadione) dhe K2 (menakinon) jan\u00eb zakonisht t\u00eb disponueshme si suplemente.<\/p>

Vitamina K \u00ebsht\u00eb nj\u00eb vitamin\u00eb thelb\u00ebsore q\u00eb trupi ka nevoj\u00eb p\u00ebr mpiksjen e gjakut, nd\u00ebrtimin e kockave dhe procese t\u00eb tjera t\u00eb r\u00ebnd\u00ebsishme. Njer\u00ebzit zakonisht e p\u00ebrdorin vitamin\u00ebn K p\u00ebr problemet e mpiksjes s\u00eb gjakut ose p\u00ebr t\u00eb p\u00ebrmbysur efektet e varfarin\u00ebs kur ndodh gjakderdhja. P\u00ebrdoret gjithashtu p\u00ebr osteoporoz\u00ebn, kancerin e gjirit, diabetin, s\u00ebmundjet kardiovaskulare, inflamacionin, s\u00ebmundjen e Alzheimerit dhe neuropatin\u00eb periferike. Marrja e vitamin\u00ebs K2 nga goja p\u00ebrmir\u00ebson forc\u00ebn e kockave dhe zvog\u00eblon rrezikun e frakturave tek njer\u00ebzit me kocka t\u00eb dob\u00ebta.<\/p>

Vitamina K2, e njohur edhe si menakinon (MK), \u00ebsht\u00eb kryesisht me origjin\u00eb bakteriale. K2 gjendet kryesisht n\u00eb ushqime t\u00eb fermentuara, mish dhe produkte qum\u00ebshti. K2 mund t\u00eb prodhohet gjithashtu nga mikrobioma e zorr\u00ebve t\u00eb njeriut, megjith\u00ebse thithja dhe transporti i vitamin\u00ebs K2 t\u00eb prodhuar n\u00eb k\u00ebt\u00eb m\u00ebnyr\u00eb jan\u00eb m\u00eb pak t\u00eb kuptuara mir\u00eb.<\/p>

K2 vjen kryesisht nga produktet shtazore, t\u00eb cilat mund ta sintetizojn\u00eb at\u00eb nga K1 q\u00eb konsumojn\u00eb duke ngr\u00ebn\u00eb bar. Nd\u00ebrsa praktikat bujq\u00ebsore i kan\u00eb zhvendosur kafsh\u00ebt nga kullotat e ushqyera me bar n\u00eb bag\u00ebti t\u00eb ushqyera me drith\u00ebra, nivelet e K2 kan\u00eb r\u00ebn\u00eb.<\/p>

Vitamina K2 \u00ebsht\u00eb thelb\u00ebsore p\u00ebr formimin e kockave, pasi \u00ebsht\u00eb e nevojshme p\u00ebr t\u00eb aktivizuar proteinat e sekretuara nga osteoblastet. K2 lidh kalciumin me matric\u00ebn e kockave dhe mund t\u00eb pengoj\u00eb resorbimin e kockave kur administrohet me vitamin\u00eb D3. Forma menakinon-7 e vitamin\u00ebs K2 \u00ebsht\u00eb treguar t\u00eb jet\u00eb ve\u00e7an\u00ebrisht e aft\u00eb n\u00eb k\u00ebt\u00eb proces.<\/p>

Shtesat e vitamin\u00ebs K2 jan\u00eb shoq\u00ebruar me nj\u00eb ulje t\u00eb konsiderueshme (af\u00ebrsisht 25%-80%) t\u00eb rrezikut t\u00eb thyerjes kur p\u00ebrdoren vet\u00ebm ose n\u00eb kombinim me vitamin\u00ebn D3 dhe kalciumin, si dhe me ruajtjen e dend\u00ebsis\u00eb s\u00eb kockave tek pacient\u00ebt me osteoporoz\u00eb. Shtesat e vitamin\u00ebs K1 kan\u00eb treguar relativisht pak p\u00ebrfitim p\u00ebr k\u00ebto rezultate.<\/p>

Nj\u00eb rishikim sistematik i literatur\u00ebs n\u00eb vitin 2017 rekomandoi konsiderimin e K2 me vitamin\u00ebn D3 dhe kalciumin si nj\u00eb trajtim shtes\u00eb p\u00ebr osteoporoz\u00ebn q\u00eb \u00ebsht\u00eb konkurrues me terapin\u00eb me bisfosfonate pa toksicitet.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

P\u00ebrdorimi i vitamin\u00ebs K2 dhe sistemi kardiovaskular<\/strong><\/p>

K2 aktivizon protein\u00ebn Gla t\u00eb matric\u00ebs (MGP), e cila parandalon formimin e depozitave t\u00eb kalciumit n\u00eb muret e en\u00ebve t\u00eb gjakut. Studimet kan\u00eb treguar se marrja adekuate e K2 n\u00eb p\u00ebrgjith\u00ebsi \u00e7liron kalciumin p\u00ebr rolet e tij m\u00eb t\u00eb dobishme, nd\u00ebrsa nj\u00eb munges\u00eb e K2 do t\u00eb \u00e7oj\u00eb n\u00eb akumulimin e kalcifikimeve.<\/p>

Kjo marr\u00ebdh\u00ebnie e thjesht\u00eb shkak-pasoj\u00eb ishte e dukshme n\u00eb Studimin prospektiv t\u00eb Roterdamit t\u00eb vitit 2004 t\u00eb bazuar n\u00eb popullat\u00eb, i cili p\u00ebrfshinte 4,807 individ\u00eb pa histori infarkti miokardi. Pas ndjekjes, studiuesit raportuan se marrja e lart\u00eb e K2 ishte e lidhur me nj\u00eb ulje t\u00eb konsiderueshme t\u00eb rrezikut t\u00eb s\u00ebmundjes koronare t\u00eb zemr\u00ebs, vdekshm\u00ebris\u00eb nga t\u00eb gjitha shkaqet dhe kalcifikimit t\u00eb r\u00ebnd\u00eb t\u00eb aort\u00ebs krahasuar me ato me marrjen m\u00eb t\u00eb ul\u00ebt t\u00eb K2. N\u00eb t\u00eb kund\u00ebrt, marrja e K1 nuk kishte asnj\u00eb p\u00ebrfitim mbrojt\u00ebs t\u00eb duksh\u00ebm.<\/p>

Nj\u00eb studim kohorte me mbi 16,000 gra pa s\u00ebmundje kardiovaskulare raportoi gjithashtu nj\u00eb korrelacion t\u00eb fort\u00eb midis rritjes s\u00eb marrjes s\u00eb K2 dhe uljes s\u00eb ngjarjeve koronare, por jo p\u00ebr K1.<\/p>

Suplementet e K2 tani jan\u00eb kujdesi standard p\u00ebr osteoporoz\u00ebn n\u00eb Japoni dhe po t\u00ebrheqin v\u00ebmendje edhe n\u00eb kulturat per\u00ebndimore.<\/p>

Studimet q\u00eb krahasojn\u00eb doza relativisht t\u00eb ul\u00ebta t\u00eb suplementeve MK-7 me placebo tek grat\u00eb n\u00eb fillim t\u00eb menopauz\u00ebs dhe n\u00eb postmenopauz\u00eb kan\u00eb dh\u00ebn\u00eb rezultate kontradiktore, ku e para nuk tregon ndryshim n\u00eb humbjen e kockave pas 1 viti, nd\u00ebrsa e dyta tregon m\u00eb pak r\u00ebnie t\u00eb lidhur me mosh\u00ebn n\u00eb p\u00ebrmbajtjen dhe dend\u00ebsin\u00eb e kockave n\u00eb qaf\u00ebn femorale dhe shpin\u00ebn lumbare pas 3 vitesh. Kjo ngre pyetje n\u00eb lidhje me gam\u00ebn optimale t\u00eb dozave K2 p\u00ebr popullata t\u00eb ndryshme, koh\u00ebzgjatjen e ndjekjes s\u00eb nevojshme p\u00ebr t\u00eb p\u00ebrcaktuar efektin e saj dhe n\u00ebse suplementet mund t\u00eb ofrojn\u00eb nivele ushqyese po aq t\u00eb p\u00ebrshtatshme sa marrja dietike.<\/p>

Ka disa raportime p\u00ebr nj\u00eb rrezik n\u00eb rritje t\u00eb s\u00ebmundjeve kardiovaskulare tek t\u00eb rriturit e moshuar dhe grat\u00eb n\u00eb postmenopauz\u00eb q\u00eb marrin suplemente kalciumi. Megjithat\u00eb, kjo lidhje \u00ebsht\u00eb v\u00ebn\u00eb n\u00eb dyshim n\u00eb studime t\u00eb tjera t\u00eb fundit, dhe udh\u00ebzimet klinike sugjerojn\u00eb se \u00e7do rrezik mund t\u00eb zbutet n\u00ebse suplementet e kalciumit merren brenda intervaleve t\u00eb tolerueshme (p.sh., jo mbi intervalin 2000-2500 mg\/d). Nd\u00ebrsa kjo lidhje vazhdon t\u00eb hetohet, roli i mundsh\u00ebm i suplementeve K2 n\u00eb balancimin e \u00e7do rreziku t\u00eb till\u00eb meriton nj\u00eb analiz\u00eb klinike shum\u00eb serioze. Disa lloje t\u00eb suplementeve K2, si\u00e7 \u00ebsht\u00eb MK-7, kan\u00eb treguar se nd\u00ebrhyjn\u00eb n\u00eb terapin\u00eb me antikoagulim, nd\u00ebrsa t\u00eb tjera, si\u00e7 \u00ebsht\u00eb MK-4, nuk mbartin rrezik hiperkoagulimi edhe n\u00eb doza relativisht t\u00eb larta. Prandaj, nd\u00ebrgjegj\u00ebsimi i mjekut p\u00ebr vetit\u00eb e ndryshme t\u00eb suplementeve t\u00eb ndryshme K2 \u00ebsht\u00eb thelb\u00ebsor tek pacient\u00ebt q\u00eb marrin terapi me antikoagulim.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
