Era owulira ng’okooye era nga tolina bulamu buli kiseera? Okoowa ne bw’oba okoze ekintu ekitono? Oluusi owulira ng’okujjukira kwo kubulako katono ne weerabira bingi? Wadde nga kino kirimu ensonga nnyingi, leero twogera ku kiriisa kye tutayogerako nnyo, naye nga tekyetaagisa ku mubiri gwaffe. Oyo ye vitamiini B12. Obutafuna kino, kwe kugamba, obutafuna bungi bwa vitamiini B12 eyeetaagisa mu mubiri, kiyinza okukosa ebintu bingi okusinga bw’olowooza. Kale leero kino tugenda kwogera mu bujjuvu, mu ngeri ennyangu ennyo.
Vitamiini B12 kye ki ddala?
Mu ngeri ennyangu, vitamiini B12 oba cobalamin ng’abasawo bwe bakiyita, kiriisa kikulu nnyo mu kukola kw’obusimu bwaffe, kwe kugamba, obusimu. Omubiri gwaffe tegusobola kugukola ku bwagwo. N’olwekyo, tulina okugifuna okuva mu mmere oba bwe kiba kyetaagisa, mu bikozesebwa mu kugatta.
Ka tulabe ebimu ku bintu ebikulu vitamiini B12 by’ekola ku mubiri gwaffe:
- Okukola DNA: Kino kiyamba okukola DNA, erimu amawulire agakwata ku buzaale agasangibwa mu buli katoffaali mu mubiri gwaffe.
- Okuliisa Obwongo n’Ensengekera y’Obusimu: Kino kyetaagisa nnyo okusobola okukola obulungi obwongo bwaffe n’obusimu mu mubiri gwonna.
- Okukola amaanyi: Kiyamba okukyusa emmere gye tulya okugifuula amaanyi (metabolism). Enkola eno ekuweereza amaanyi okusigala ng’olina amaanyi olunaku lwonna.
- Okukola obutoffaali obumyufu: Vitamiini B12 yeetaagibwa nnyo okusobola okukola obulungi obutoffaali obumyufu, obutambuza omukka gwa oxygen mu mubiri gwonna.
Teebereza, bwe tulya emmere erimu vitamiini B12 (okugeza, ekitundu ky’ekyennyanja), asidi eziri mu lubuto lwaffe zaawulamu vitamiini B12 ku puloteyina eri mu kitundu ky’ekyennyanja ekyo. Olwo, vitamiini eno B12 yeegatta ne puloteyina ey’enjawulo eyitibwa ‘intrinsic factor’, ekolebwa mu lubuto lwennyini, n’eyingizibwa mu mubiri. Singa wabaawo obuzibu mu nkola eno, tusobola okufuna obuzibu bwa vitamiini B12.
Ani ali mu bulabe obw’amaanyi obw’okulwala obutaba na vitamiini B12?
Okutwalira awamu, abantu abalya emmere ennungi tebatera kufuna bbula lino. Kyokka abantu abamu bali mu bulabe bwa maanyi.

| Abantu abalina ebika by’obulwadde bw’okukendeera kw’omusaayi | Mu kukendeera kw’omusaayi okw’obulabe, omubiri tegusobola kukola ‘intrinsic factor’, ekigulemesa okunyiga vitamiini B12. |
Singa wabaawo obuzibu, obubonero ng’okukoowa , okukoowa, okubulwa okujjukira, n’okuzimba ebitundu by’omubiri biyinza okulabika.
Emigaso gya vitamiini B12 eri obulamu
Okukuuma omutindo gwa vitamiini B12 mu bulamu obulungi kituwa emigaso egiwerako eri obulamu.
Okukendeeza ku bukoowu n’obunafu
Bw’oba olina obuzibu bwa vitamiini B12, oyinza okuwulira ng’okooye era ng’oli munafu buli kiseera. Kino kiri bwe kityo kubanga B12 yeetaagibwa okukola amaanyi n’okukola obutoffaali obumyufu obutambuza omukka gwa oxygen. Okumira B12 mu kiseera kino kiyinza okulongoosa ennyo amaanyi go. Wabula okunoonyereza kuzudde nti okumira eddagala lya B12 tekikyongera nnyo maanyi oba omutindo gw’emizannyo mu bantu abatalina bbula .
Okuwagira obulamu bw‟omutwe
Vitamiini B12 eyamba okukola serotonin, ekirungo ekitambuza obusimu obutereeza embeera yaffe. N’olwekyo, wabaddewo akakwate wakati w’emiwendo gya B12 emitono n’okwennyamira. Okunoonyereza okumu kulaga nti okumira eddagala lya vitamiini B12 ng’ojjanjabibwa ekiwuubaalo kiyinza okuyamba okumalawo obubonero.
Obukulu nga oli lubuto
Ebbula lya Vitamiini B12 kitera okubaawo ng’oli lubuto. Naye kiyinza okukosa omwana. Singa maama ow’olubuto alina emiwendo gya B12 emitono, emikisa gy’omwana okufuna obuzibu mu nseke z’obusimu n’obuzito obutono bw’azaalibwa bweyongera. Era kiyinza okuvaako okuvaamu olubuto n’okuzaala nga tannatuuka.
Naye kimanye nti, okunoonyereza okumu kulaga nti Vitamiini B12 omungi ng’oli lubuto kiyinza okuba eky’obulabe eri omwana. N’olwekyo, bw’oba oli lubuto oba ng’ogezaako okufuna olubuto, kakasa nti oyogera n’omusawo wo nga tonnamira ddagala lya vitamiini.
Enkola y’obwongo n’okujjukira
Wadde ng’okubulwa okujjukira kitera okubaawo n’emyaka, obutaba na vitamiini B12 kiyinza okwonoona embeera eno. Okukendeera kw’obutoffaali bw’obwongo (neurons) (brain atrophy) kukwatagana n’okubulwa okujjukira n’okubulwa amagezi. Okunoonyereza okumu kulaga nti okukuuma emiwendo gya B12 egimala kiyinza okukendeeza ku nkola eno.
