Eyaziwa kakhulu ngeqhaza layo elibalulekile ekwenzeni i-clotting blood (i-K ingukuthi "i-koagulation"), i- Vitamin K kufanele ihlonishwe ngokubambisana kwayo ekuthintekeni kwethambo. I-Vitamin K ivumela umzimba ukuba usebenzise i-calcium edingekayo ekuthatheni amathambo nezinyosi.
Ukugcina amathambo akho aqine kuyingxenye ebalulekile yokuhlala uphilile ngeminyaka. Ngokusho kweNational Osteoporosis Foundation, abesifazane abangamaphesenti angu-50 namaphesenti angama-25 amadoda angaphezu kuka-50 bazoba nokuhlukunyezwa okwe-osteoporosis ngesikhathi sokuphila kwabo, futhi lokho kuphuka kungaba yingozi kakhulu, okubangelwa ubuhlungu, ukukhubazeka, ukulahlekelwa ukuzimela, nokufa okukhulu ingozi.
Amafomu we-Vitamin K
Kunezinhlobo ezimbili zemvelo ze-Vitamin K. Vitamin K1 zitholakala ngobuningi emifino emifino, imifino eluhlaza efana ne-kale, imifino ye-collard, isipinashi, nemifino yesinaphi. I-Vitamin K2 incane eyaziwayo futhi ayitholakali kalula ekudleni okucebile. Umzimba womuntu ungakwazi ukuhlanganisa ezinye i-K2 kusuka ku-K1, futhi amabhaktheriya emathumbu angakhipha i-K2, kodwa kuphela ngemali encane kakhulu. Uma ulandela ukudla okunomsoco-okunomsoco, okutshala izitshalo , okuncane kakhulu kwemikhiqizo yezilwane kanye nemifino eminingi, ubhontshisi, amantongomane kanye nembewu, ukufakazela nge-K2 cishe kuhlakaniphile.
Izinzuzo zezempilo zikaVithamini K
EJapane, lapho i-natto, ukudla okunothileyo okunothileyo e-Vitamin K2 eyingxenye ejwayelekile yokudla, kuye kwaba nokukhubazeka okuphansi kwe-hip fracture. Ucwaningo luye lwafakazela ukuthi ukukhubazeka okuphansi kwe-hip kuvele kuyingxenye ku-natto. Ukulandela lokhu, izifundo eziningana zathola ukwesekwa nge-Vitamin K2 ukuze kusebenze ngokukhethekile ekuthuthukiseni impilo yethambo.
Ukubuyekezwa kwezilingo ezilawulwa ngokungahleliwe kutholakale ukuthi i-Vitamin K2 inciphise ukulahleka kwethambo futhi inciphise amathuba okuhlukana: ukuphuka kwama-vertebral ngamaphesenti angu-60, ukuphuka kweqhwa ngamaphesenti angu-77, futhi yonke imifucumfucu engeyona i-vertebral ngamaphesenti angu-81.
Kulabo besifazane abanesifo se-osteoporosis, i-Vitamin K2 supplementation iye yaboniswa ukunciphisa ingozi yokuphuka, ukunciphisa ukulahleka kwethambo, nokwandisa amathambo amaminerali.
Emadodeni ase-postmenopausal athatha ama-vitamin K2 ezincelisayo nsuku zonke iminyaka emithathu, wehla ekulahlekelweni kwethambo kanye ne-bone mineral mass, futhi kutholakale amandla okwanda kwamathambo kulabo abathatha isamba ngokuhambisana nalabo abanikezwa i-placebo.
Ngaphezu kokubaluleka kokukhula kwethambo empilweni, kunobunye ubufakazi bokuthi i-K2 inezinzuzo ezengeziwe (ezihlukile kwalezo ze-K1) zesistimu zenhliziyo. Ukudla okuphakeme kwe-vitamin K2 kuye kwaxhunyaniswa nokulingana okuphansi kwe-coronary calcification, okusiza ukugcina udonga lwe-artery lukhulu futhi luvimbele ukuqina. Ukubalwa komthambo we-Coronary kuyisimo sezenzakalo zenhliziyo, njengokuqina komzimba.
Ngo-2004, i-Rotterdam Study yembula ukuthi ukudla okukhulayo okwenziwe ikakhulukazi nge-Vitamin K2 kunciphisa kakhulu ingozi ye-coronary disease ngamaphesenti angu-50 uma kuqhathaniswa nokudla okuncane okudlayo kwe-Vitamin K2. Imiphumela efanayo yafunyanwa ngo-2009, futhi ukubuyekezwa okuhlelekile kwezifundo eziningana ngo-2010 kwatholakala ukuthi ukudla okungaphezulu kukaVithamini K2 kwakuhlobene nengozi ephansi. Ayikho inhlangano enjalo etholakala, kodwa, i-Vitamin K1.
Ikhono le-Vitamin K2 lokuvikela uhlelo lwe-cardiovascular against calcification lungaba ngenxa yokungafani kokumunca noma umsebenzi wezinto eziphilayo phakathi kwamafomu we-Vitamin K.
Izifundo zesikhathi esizayo ziyadingeka ukuze ziqonde kangcono amakhono ka-Vitamin K2 kanye nokuhlola ukuthi kunezinye izinzuzo ezikhethekile ku-K1 noma ku-K2. Kunobunye ubufakazi bokuthi i-Vitamin K ihileleka ekutheni i-insulin metabolism, futhi ukudla okunamandla kwamavithamini K1 no-K2 kuhlotshaniswa nobungozi obuncane besifo sikashukela sohlobo lwesibili. Okwamanje, ukwengeza nge-Vitamin K2 (ngaphezu kokudla imifino yakho ) kungenzeka ukunikeza izinzuzo.
