Ucwaningo lwakamuva lwe-Vitamin K2 MK7

I-Vitamin K2 MK7 (Menaquinone-7) iwuhlobo olubalulekile nolusebenzayo lwe-Vitamin K2, oluthola ukunakwa okukhulu ngenxa yezindima zalo ezibalulekile empilweni yenhliziyo nemithambo yegazi. Nansi incazelo eningiliziwe.

· Ukuhlonza Amakhemikhali: I-Vitamin K2 iyingxenye yomndeni we-menaquinone (MK), ebonakala ngochungechunge oluseceleni lwamayunithi e-prenyl aphindaphindayo. I-MK7 inalawa mayunithi e-isoprenoid angu-7 ngokukhethekile (“i-MK” imele i-Menaquinone, “7″ imele ubude bochungechunge).

· Imithombo Yemvelo:

· Ukudla Okubilisiwe: Umthombo wokudla ocebile kakhulu yi-natto (ukudla kwendabuko kwaseJapane okwenziwe ngobhontshisi obilisiwe). Okunye ukudla okubilisiwe njengoshizi othile (isib. iGouda, iBrie) kanye ne-sauerkraut kuqukethe amanani amancane, aguquguqukayo.

· Imithombo Yezilwane: Itholakala ngobuningi obuncane kumaqanda, esibindini, nasenyameni enamafutha evela ezilwaneni ezidla utshani.

· Izithasiselo: Zitholakala kabanzi njengesengezo sokudla, ngokuvamile ezitholakala ekuvutshelweni kwe-natto noma ezikhiqizwa ngokwenziwa. Ngokuvamile zihlanganiswa ne-Vitamin D3 kanye ne-calcium ukuze kube nemiphumela yokusebenzisana.

Lona umqondo oyinhloko ohlukanisa i-Vitamin K2 (ikakhulukazi i-MK7):

· Ivuselela i-Matrix Gla Protein (MGP): I-MGP iwumvimbela onamandla we-vascular calcification. Ibopha kuma-ion e-calcium ezindongeni zemithambo yegazi futhi iwavimbele ekungeneni ezicutshini ezithambile (imithambo yegazi, izinso). I-MK7 ivuselela i-MGP. Ngaphandle kwe-K2 eyanele, i-MGP ihlala ingasebenzi, okwandisa ingozi yokuqina kwemithambo yegazi kanye nesifo senhliziyo.

· Ivuselela i-Osteocalcin: I-Osteocalcin iyiprotheni ekhiqizwa yi-osteoblasts (amaseli akha amathambo). Umsebenzi wayo ukubopha i-calcium nokuyihlanganisa ku-matrix yamathambo, iqinise amathambo. I-MK7 ivuselela i-osteocalcin.

· Isifaniso esithi “Umqondisi We-Calcium”: Cabanga nge-Vitamin D “njengomlindi wesango” oqinisekisa ukuthi i-calcium eyanele imuncwa isuka emathunjini iye egazini. I-Vitamin K2 (MK7) isebenza “njengomqondisi wethrafikhi” noma “i-shuttle,” eqinisekisa ukuthi i-calcium ifakwa emathanjeni (nge-osteocalcin) futhi igcinwe ngaphandle kwemithambo yegazi (nge-MGP).

1. Impilo Yenhliziyo Nemithambo Yegazi:

· Kunciphisa Ukuqina Kwemithambo kanye Nokwakheka Kwe-Calcification: Izifundo eziningi zokuhlola kanye nokungenelela zixhumanisa ukudla okuphezulu kwe-K2 (MK7) kanye nengozi encishisiwe yesifo senhliziyo, ukufakwa kwe-calcium emithanjeni yegazi, kanye nokufa. Ucwaningo lwe-ROTTERDAM luwucwaningo oludumile lweqembu elibonisa le nzuzo.

· Kuthuthukisa Ukunwebeka: Ukwengezwa (isb., 180-360 µg/ngosuku iminyaka eminingana) kuye kwabonakala kuthuthukisa ukuguquguquka kwemithambo yegazi.

2. Impilo Yamathambo:

· Yehlisa Ingozi Yokuphuka Kwamathambo: Ikakhulukazi abesifazane asebekhulile. I-K2 isebenza ngokubambisana ne-Vitamin D kanye ne-calcium ukuthuthukisa ubuningi bamaminerali ethambo (i-BMD) nokunciphisa ukwanda kokuphuka kwamathambo (umgogodla kanye nenqulu).

· Kuvimbela i-Osteoporosis: Ngokusebenzisa ngokugcwele i-osteocalcin, isekela inqubo yokuvuselela amathambo, ikhuthaza ukwakheka kwamathambo kunokumuncwa kabusha.

3. Ezinye Izicelo Ezingaba Khona (Ucwaningo Oluvelayo):

· Ukuzwela kwe-insulin kanye nesifo sikashukela: I-Osteocalcin, uma isebenza yi-K2, ingadlala indima ekuthuthukiseni ukuzwela kwe-insulin.

· Impilo Yezinso: Kungasiza ekuvimbeleni ukugcwala kwemithambo yegazi ezigulini ezinesifo sezinso esingamahlalakhona (i-CKD), yize ukusetshenziswa ku-CKD kudinga ukubhekwa ngudokotela ngenxa yezinkinga ezingaba khona.

· Impilo Yamazinyo: Njengethambo, ingase isekele ukwakheka kwamaminerali ezinyo nge-osteocalcin.

· Impilo Yokuqonda: Olunye ucwaningo lokuqala luxhumanisa impilo yemithambo yegazi (esekelwa yi-K2) nengozi encishisiwe yokwehla kwengqondo.

Faka i-Vitamin K2 MK7 Vitamin K2 MK4

Umthombo Ngokuyinhloko uvela ekuvutshelweni kwamagciwane (i-natto). Kutholakala emikhiqizweni yezilwane; izithasiselo eziningi zenziwe ngokwenziwa.

Isikhathi Esiyisigamu Sempilo (~amahora angu-72). Inikeza amazinga egazi azinzile futhi aqhubekayo kusukela kumthamo owodwa. Omfushane (~amahora angu-1-2). Kudinga umthamo ovamile (ngokuvamile izikhathi eziningana ngosuku).

Ukutholakala kwe-Bioavailability Kuhle kakhulu; isikhathi sayo eside sokuphila siholela emazingeni aphezulu futhi azinzile e-serum. Ukususwa okuhle kodwa okusheshayo kunciphisa ukuqongelela kwezicubu.

Isilinganiso Esijwayelekile esingu-90-360 µg/ngosuku sivame ukusetshenziswa ekungezeni. Ngokuvamile sisetshenziswa kumithamo yezokwelapha (1.5-45 mg/ngosuku) ezifundweni zezokwelapha.

Ukusetshenziswa Okuyinhloko Impilo yokuvimbela yesikhathi eside yamathambo nemithambo yegazi (isengezo sokudla). Umuthi kadokotela (eJapane) we-osteoporosis kanye nokulahlekelwa amathambo okubangelwa yi-steroid.

Ubufakazi Idatha enamandla ye-epidemiological kanye neyandayo yesilingo semitholampilo yezinzuzo zenhliziyo nemithambo yegazi. Idatha enamandla yesilingo semitholampilo yezinzuzo zamathambo ngemithamo ephezulu, yemithi.

Isiphetho: I-MK7 ngokuvamile ikhethwa kakhulu ekusetshenzisweni kwansuku zonke ngenxa ye-pharmacokinetics yayo ephezulu (ingxenye yempilo ende), okuvumela ukunqunywa kanye ngosuku kanye nokusebenza okuqhubekayo kwamaprotheni ancike ku-K.

· Isilinganiso Esijwayelekile Sokwengeza: Sisukela kuma-microgram angu-90 (µg) kuya ku-360 µg ngosuku. Izifundo eziningi ngezinzuzo zenhliziyo zisebenzisa cishe ama-µg angu-180-200 ngosuku.

· Ukuphepha: Kuphephile kakhulu ngemithamo enconyiwe kubantu bonke. Akukho silinganiso sobuthi esaziwayo esitholiwe.

· Ukusebenzisana Okubalulekile – Ama-Anticoagulant (i-Warfarin/i-Coumadin):

· I-Vitamin K ilwa nomphumela we-Warfarin. Iziguli ezisebenzisa i-Warfarin kumele zigcine ukudla i-Vitamin K njalo (kusukela ekudleni nasezithasiseleni) ukuze zigcine umthamo wazo wemithi uzinzile.

· AKUFANELE baqale noma bayeke izithasiselo ze-K2 ngaphandle kokuqashwa okuseduze kwezokwelapha kanye nokuqapha njalo i-INR. Ama-anticoagulant amasha (ama-DOAC afana ne-apixaban, i-rivaroxaban) awasebenzisani ne-Vitamin K.

· Ukusebenzisana: Njalo thatha neVithamini D3. Ziyinhlanganisela enamandla yokusebenzisana. I-calcium ne-magnesium nazo ziyizakhamzimba ezibalulekile.

· Uhlobo: Ama-softgel noma ama-capsule ane-carrier esuselwe kumafutha (isb., uwoyela womnqumo, uwoyela we-MCT) afaneleka kakhulu, njengoba i-Vitamin K2 incibilika emafutheni.

· Amafomula Okuhlanganiswa: Funa imikhiqizo ehlanganisa i-K2 (MK7) + D3. Ukwengeza inani elincane le-Vitamin K1 nakho kungaba yinzuzo esimweni se-K esiphelele.

· Ikhwalithi: Khetha izinhlobo ezisebenzisa i-MK7 eguquguqukayo ngokuphelele (ifomu elisebenzayo; eminye imikhiqizo yokwenziwa ingase iqukathe i-isomer ye-cis engasebenzi kakhulu).

· Indawo Yokugcina: Gcina endaweni epholile, emnyama. Izinzile ezithasiselweni uma ivikelwe ekukhanyeni nasekushiseni.

Ngamafuphi, i-Vitamin K2 MK7 iyisakhi esibalulekile esiqondisa i-calcium emasakeni ngenkathi ivikela imithambo yegazi kanye nezicubu ezithambile ekufakweni kwe-calcium. Ukuphila kwayo isikhathi eside kanye nobufakazi obuqinile kwenza kube yingxenye ebalulekile yendlela yokuvimbela impilo, ikakhulukazi empilweni yenhliziyo nemithambo yegazi, uma isetshenziswa kanye ne-Vitamin D3.
