Bidh an dòigh-rianachd gnàthach a’ toirt àrdachadh luath air an t-searaid, ach bidh B12 beòil aig dòs àrd gu tric a’ ceartachadh dìth cho èifeachdach thar sheachdainean. Is e an adhbhar agus cho dona sa tha an dìth an rud a tha a’ dearbhadh an roghainn – chan ann a-mhàin roghainn pearsanta.
- Àrdachadh searum as luaithe: Bidh stealladh B12 a-steach don fhèith de 1,000 microgram a’ togail B12 san fhuil taobh a-staigh uairean, fhad ‘s a thogas clàran barrachd mean air mhean thar làithean.
- Aon ionadachadh co-ionann: Faodaidh cyanocobalamin beòil 1,000-2,000 microgram gach latha toraidhean fala agus comharraidhean coltach ris an fheadhainn a gheibhear le làimhseachadh a-steach don fhèith a choileanadh airson mòran inbhich.
- Comharra airson stealladh: Tha comharran eanchainn dona, anemia ro mhòr, neo-chomas clàran a ghabhail, no gabhail neo-earbsach mar as trice a’ ceadachadh stealladh fo stiùir clionaigeach.
- Toradh crìochan: Mar as trice thathas a’ meas gu bheil searum B12 fo 180 pg/mL (133 pmol/L) a’ nochdadh dìth; bidh 180-350 pg/mL gu tric a’ feumachdainn dearbhadh le MMA no homocysteine.
- Gacaireachd fulangach: Bidh timcheall air 1% de dhòs àrd de B12 beòil a’ dol a-steach tro sgaoileadh fulangach, is e sin as coireach gum faod clàr de 1,000 microgram obrachadh a dh’ aindeoin milleadh air an "intrinsic factor".
- Cuin ath-dheuchainn: Mar as fheumais gu gnàthach na SA is freagairt clionaigeach aig 4-8 seachdainean na ìre B12 air a tharraing dìreach às dèidh làimhseachadh.
- Puing sàbhailteachd: Na bi a' làimhseachadh cugallachd neo-mhìnichte le searag searbhagach a-mhàin; faodaidh folate anemia a leasachadh fhad 's a tha milleadh nerve co-cheangailte ri B12 a' dol air adhart.
- Tha cìs a' cunntadh: Feumaidh Metformin, luchd-dìon pumpa pròtain, daithead vegan, coeliac tinneas, obair-lannsa stamag agus pernicious anemia planaichean leanmhainn eadar-dhealaichte.
Dè an roghainn a thogas ìrean de B12 nas luaithe?
Bidh steallaidhean B12 a' togail na h-ìre serum thomhais nas luaithe na tablaidean, gu tric taobh a-staigh uairean, oir bidh iad a' seachnadh a' ghalair. Airson a' mhòr-chuid de dh'inbhich seasmhach le dìth dearbhte, ge-tà, faodaidh dòs beòil 1,000-2,000 microgram gach latha stòran bodhaig ath-lìonadh agus cunntasan fala a leasachadh thar seachdainean aig ìre coltach ri clionaigeach.
Bidh stealladh a' cruthachadh mullach geur tràth oir tha hydroxocobalamin no cyanocobalamin air a lìbhrigeadh dìreach a-steach do fhèith agus an uairsin cuairteachadh. Chan eil am mullach obair-lann sin mar an ceudna ri stòran nèise ath-leasaichte no gnìomh nerve air a chàradh; nam chleachdadh, tha faighinn seachad air comharraidhean air a thomhas ann an seachdainean gu mìosan, chan ann an ath latha.
Tha an coimeas practaigeach gu tric uairean an aghaidh làithean airson dùmhlachd serum, ach timcheall air 4-8 seachdainean airson freagairt hematologic ciallach le slighe iomchaidh sam bith. Bidh reticulocytes gu tric a' èirigh aig latha 3-5, bidh hemoglobin a' tòiseachadh air leasachadh às dèidh mu 1-2 seachdainean, agus faodaidh macrocytosis suas ri 8 seachdainean a thoirt airson socrachadh.
Tha Kantesti na Anailisiche deuchainn fala AI a chuireas B12 ri taobh MCV, hemoglobin, folate, creatinine agus toraidhean roimhe seach a bhith a' làimhseachadh spike B12 às dèidh làimhseachadh mar dhearbhadh gu bheil an duilgheadas bunaiteach air fhuasgladh. Faodaidh leughadairean cuideachd an toradh aca a choimeas leis an stiùireadh raon iomraidh B12.
Dè a tha “nas luaithe” a' ciallachadh dha-rìribh
Tha toradh àrd às dèidh stealladh a' dearbhadh nochdadh o chionn ghoirid, chan e gu riatanach lìbhrigeadh ceallach iomchaidh. Tha searag methylmalonic, toraidhean neurological agus an clàr-ama SA nas fhiosraiche nuair a bha an dearbhadh tùsail neo-chinnteach.
Mar a tha gabhail ri B12 beòil ag obair nuair a tha an "intrinsic factor" ìosal
Faodaidh B12 beòil àrd-dòs obrachadh eadhon nuair a tha gabhail a-steach factar-intrinsec air a mhilleadh oir tha cuibhreann beag a' tighinn a-steach le sgaoileadh fulangach. Mu 1% de dòs 1,000 microgram dh'fhaodadh a bhith air a ghabhail a-steach gu fulangach, a' toirt timcheall air 10 microgram—fada os cionn na cuibheasachd riatanach làitheil de 2.4 microgram airson inbhich.
Feumaidh B12 bìdh a tha ceangailte ri biadh a bhith air a leigeil ma sgaoil le searbhag stamag, a bhith ceangailte ri factar-intrinsec, agus a bhith air a ghabhail a-steach anns an ileum deireannach. Tha an siostam ioma-cheum seo a' mìneachadh carson a dh'fhaodadh solar searbhag fad-ùine, gastritis fèin-dìon, galar ileal agus modhan bariatric a bhith ag adhbhrachadh dìth; tha e cuideachd a' mìneachadh carson a tha multivitamin àbhaisteach mar as trice cus beag dòs airson làimhseachadh.
Tha gabhail a-steach B12 beòil an urra ri dòs ach chan ann gu dìreach. Bidh slighe factar-intrinsec a' fàs làn aig timcheall air 1.5-2 microgram gach biadh, fhad 's a tha sgaoileadh fulangach a' fàs feumail gu clionaigeach a-mhàin le tablaidean milligram-raon. Tha stuth-dìon 50 microgram reusanta airson casg a chuir air cuid de dhaoine, ach chan eil e co-ionann ri 1,000 microgram airson dìth stèidhichte.

Dè tha deuchainnean clionaigeach a’ nochdadh mu chlàran an aghaidh stealladh
Randomized evidence suggests oral B12 at 1,000-2,000 micrograms daily can be as effective as intramuscular B12 for many people with deficiency. The evidence base is not enormous, and it contains fewer patients with severe neurological disease than clinicians would like.
The Cochrane review by Wang and colleagues found that high-dose oral B12 produced similar B12 blood-level responses to intramuscular treatment in the small randomized trials available (Wang et al., 2018). One study used 2,000 micrograms orally each day; another used 1,000 micrograms orally after an initial schedule, so “oral therapy” does not mean a low-dose supermarket product.
The earlier trial by Kuzminski et al. reported greater serum B12 concentrations with 2,000 micrograms oral cyanocobalamin than with a 1,000 microgram injection regimen, yet clinical outcomes were the question that mattered (Kuzminski et al., 1998). The evidence is honestly mixed on the ideal protocol because trials used different injection intervals and follow-up periods.
A tablet only works if it is taken. Missed daily doses can make an injection administered every 2-3 months more dependable in real life, especially for frail adults or people with complex medication schedules. Our stiùireadh clàr-ama deuchainn fala can help distinguish a true treatment change from a poorly timed retest.
Cuin a tha stealladh B12 riatanach gu meidigeach
B12 injections are usually medically necessary when deficiency is severe, neurological symptoms are present, oral intake is impossible, or absorption and adherence cannot be relied upon. They are not automatically mandatory simply because pernicious anemia is suspected, provided high-dose oral treatment and follow-up are feasible.
Urgent clinician assessment is appropriate for new gait imbalance, progressive numbness, weakness, confusion, visual change, marked anemia, or pregnancy with significant deficiency. Neurological B12 injury can become partly irreversible; in that setting, I would not delay parenteral therapy while debating convenience.
NICE guideline NG239 advises intramuscular treatment when malabsorption is suspected or confirmed and recommends lifelong intramuscular replacement for autoimmune gastritis in many cases (NICE, 2024). Practice varies internationally: some clinicians use oral 1-2 mg daily in reliable patients with pernicious anemia, while others favour injections because the consequences of a lapse are higher.
A hemoglobin below 80 g/L, symptomatic breathlessness, tachycardia, or possible spinal-cord involvement warrants prompt medical review rather than self-treatment. To understand how anemia patterns appear on routine testing, see what a full blood count includes.
Dòsan làimhseachaidh dìth B12 a bhios clionaichean a’ cleachdadh
Common oral treatment doses are 1,000-2,000 micrograms daily, while common intramuscular regimens use 1,000 micrograms per dose with an initial loading phase. The product, national guideline and cause of deficiency determine the exact schedule.
In UK practice, hydroxocobalamin 1,000 micrograms intramuscularly is often given three times weekly for 2 weeks when there is no neurological involvement, then every 2-3 months for maintenance; protocols differ by local service. With neurological features, initial doses are often given every other day until no further improvement, then maintenance follows specialist advice.
A typical oral plan is cyanocobalamin 1,000 micrograms daily for 8-12 weeks, followed by 1,000 micrograms daily or a lower maintenance schedule if diet was the sole cause. Sublingual products are not proven to outperform swallowed tablets; once dissolved, most is swallowed anyway.
Do not improvise a loading regimen from social-media advice. The methylated B12 versus cyanocobalamin comparison explains why the dose and consistency generally matter more than marketing claims about the B12 form.
Mar a mhìneachadh toradh ìosal no crìochan B12
Serum B12 below 180 pg/mL (133 pmol/L) usually supports deficiency, while values from about 180-350 pg/mL are an indeterminate zone in which MMA or homocysteine can clarify cellular deficiency. Individual laboratory intervals differ, and a normal serum value does not fully exclude deficiency after recent supplementation.
Methylmalonic acid rises when B12-dependent metabolism is impaired, but reduced kidney function can raise MMA independently. Homocysteine may rise with B12 deficiency, folate deficiency, vitamin B6 deficiency, hypothyroidism and renal impairment, so neither confirmatory test should be read in isolation.
Macrocytosis is supportive but not required. A mean corpuscular volume above 100 fL raises suspicion for B12 or folate deficiency, alcohol exposure, liver disease, hypothyroidism, marrow disorders or medication effects; about one quarter of symptomatic B12-deficient patients may have a normal MCV.
Kantesti AI interprets B12 results by checking the phàtrain of MCV, RDW, hemoglobin, folate and historical values, including clues that a folate supplement may be masking macrocytosis. Our article on leanmhainn MCV àrd covers the common alternatives.
Bidh anemia pernicious ag atharrachadh a’ phlana fad-ùine, chan ann an-còmhnaidh an t-slighe
Pernicious anemia is autoimmune loss of intrinsic-factor function, and it requires lifelong B12 replacement after diagnosis. Injections offer dependable delivery, but high-dose oral therapy may still maintain adequate status in selected, closely monitored adults.
The tests most often used are intrinsic-factor antibodies and parietal-cell antibodies, alongside B12, CBC and sometimes gastrin. A positive intrinsic-factor antibody is highly specific but not very sensitive, so a negative result does not rule the condition out; this is one of those areas where context matters more than a single antibody.
Pernicious anemia is more than an absorption problem. Autoimmune gastritis can coexist with iron deficiency before B12 deficiency becomes obvious, and long-standing disease carries gastric surveillance considerations that should be discussed with the treating clinician. Our pernicious anemia testing guide details the diagnostic sequence.
Tha Kantesti na àrd-ùrlar mìneachaidh deuchainn fala AI used across 127+ countries, but an AI interpretation cannot diagnose autoimmune gastritis or select a lifelong injection interval. A clinician needs to connect symptoms, antibodies, endoscopic history and the laboratory pattern.
Carson a dh’ fheumas comharran eanchainn gnìomh clionaigeach nas luaithe
Tingling, loss of vibration sense, unsteady walking, cognitive change or weakness with low B12 should trigger prompt in-person assessment and usually injectable treatment. Nerve recovery is less predictable than anemia recovery and may remain incomplete after months of deficiency.
The dorsal columns and peripheral nerves are vulnerable to B12 deficiency, producing a pattern clinicians call subacute combined degeneration in advanced cases. A normal hemoglobin does not protect against this; I have seen patients whose numb feet and abnormal vibration sense preceded any obvious anemia.
Improvement often starts within 1 week of effective therapy, but sensory symptoms can take 3-12 months and may not resolve completely. The safest approach is to record baseline function—walking distance, falls, hand dexterity, vibration sense—because a rising serum B12 alone is not a recovery score.
Neuropathy also has many mimics, including diabetes, alcohol-related nerve injury, thyroid disease, excess vitamin B6 and some medicines. Patients with tingling can use our vitamin B6 nerve-symptom guide to prepare better questions, but progressive weakness needs medical care now.
Cuin a tha clàran gu leòr airson dìth B12 bho bhiadh
Tablets are usually enough when low B12 results from inadequate intake and the gut can absorb supplements. Vegans, people eating very little animal-source food, and adults with temporary dietary restriction commonly respond well to oral cyanocobalamin 1,000 micrograms daily.
Vitamin B12 is naturally concentrated in animal-derived foods and fortified foods, so a strict vegan diet needs a reliable fortified-food or supplement strategy. Plant foods marketed as natural B12 sources are inconsistent; seaweed and fermented foods can contain inactive analogues that are not dependable treatment.
Dietary deficiency should still prompt a short history. A 23-year-old vegan with B12 of 142 pg/mL, normal MMA after treatment and no bowel symptoms is different from a 68-year-old with the same result, weight loss and iron deficiency. Age, medicines and gastrointestinal symptoms change the work-up.
For food planning, our water-soluble vitamin guide separates prevention doses from deficiency treatment. Do not assume nutrition alone will correct neurological symptoms quickly enough.
Leigheasan agus suidheachaidhean caolain a dh’ atharraicheas an roghainn làimhseachaidh B12
Metformin, acid-suppressing medicines, coeliac disease, Crohn’s disease affecting the ileum, pancreatic insufficiency and gastric surgery can all reduce B12 availability. A tablet trial may be reasonable in some cases, but injections are often chosen when absorption is uncertain or symptoms are significant.
Metformin-associated B12 deficiency is common enough that regulators advise checking levels in patients with neuropathy, anemia or other risk factors, particularly at higher doses or with long duration. The mechanism likely involves calcium-dependent uptake of the B12-intrinsic factor complex in the ileum, not simply poor diet.
After sleeve gastrectomy or gastric bypass, treatment decisions should follow the bariatric team’s protocol because iron, folate, thiamine, vitamin D and copper may be affected together. Diarrhea, low albumin, unexplained weight loss or greasy stools should prompt investigation rather than endless supplement changes.
Low copper can also cause anemia and neurologic symptoms that resemble B12 deficiency, especially after bariatric surgery or excessive zinc. Our low copper clinical clues explain why checking only B12 can miss the real explanation.
Cuin a nì thu ath-dheuchainn às deidh làimhseachadh B12
A CBC and symptom review at about 4-8 weeks are generally more useful than repeating serum B12 immediately after an injection or tablet course. A very high B12 result soon after treatment mainly reflects the dose that was taken.
A reticulocyte response around day 3-5 offers an early clue that marrow production is recovering, while hemoglobin should rise over the following weeks if B12 deficiency was a key driver. Lack of improvement should reopen the differential: iron deficiency, ongoing blood loss, folate deficiency, inflammation, renal disease or an incorrect diagnosis.
For an uncomplicated dietary deficit, I often recheck CBC and B12 at 8-12 weeks, then confirm a sustainable maintenance plan. For neurological disease, autoimmune gastritis, pregnancy, renal impairment or multiple deficiencies, follow-up needs to be individualized and commonly begins earlier.
Kantesti’s Inneal mion-sgrùdaidh deuchainn fala le cumhachd AI can compare sequential B12, MCV, RDW and hemoglobin results rather than displaying each draw as a disconnected event. The stiùireadh coimeas obair-lann taobh ri taobh shows what to record between tests.
Carson nach eil toradh àrd B12 às deidh làimhseachadh an-còmhnaidh misneachail
A high B12 level after an injection or high-dose tablet commonly reflects supplementation and does not prove that symptoms have another cause. Conversely, unexplained persistent B12 elevation without supplements deserves clinical review, especially when liver, kidney or blood-count abnormalities coexist.
Serum B12 can exceed a laboratory upper limit of roughly 900-1,000 pg/mL after treatment, depending on assay and timing. This is expected and usually not toxic; B12 has no established tolerable upper intake level in healthy adults because excess is largely excreted, although acneiform eruptions occur in a small minority.
The question I ask is simple: was the sample drawn after a supplement, injection, multivitamin, energy drink or fortified product? If not, elevated B12 can accompany liver disease, reduced renal clearance, inflammation or certain hematologic conditions, and it needs context rather than alarm.
Ar high vitamin B12 guide explains the distinction between expected supplement-related elevation and an unexplained laboratory clue.
Mearachdan cumanta ann an làimhseachadh B12 a chuireas dàil air faighinn seachad
The most consequential mistake is taking folic acid alone when B12 deficiency has not been excluded. Folic acid can normalize anemia while allowing B12-related nerve injury to progress, particularly when doses exceed the usual dietary range.
Do not use symptoms alone to decide between injections and tablets. Fatigue, brain fog and low mood are real but nonspecific; sleep loss, thyroid disease, iron deficiency, depression, diabetes and medication effects can produce similar complaints. A B12 result near 250 pg/mL warrants confirmation more often than an automatic injection.
Another mistake is delaying a test until after starting supplements when possible. Even 50-500 micrograms daily can shift serum B12 enough to complicate diagnosis, although urgent neurological symptoms should always be treated first. The high folate and hidden B12 issue is particularly relevant for people taking prenatal or energy supplements.
As of August 27, 2026, my advice as Dr. Thomas Klein is to choose the least burdensome route that is medically reliable, then verify recovery with symptoms and trends. Injection treatment is excellent medicine when indicated; it is not inherently stronger medicine for every low result.
Frèam-obrach co-dhùnaidh practaigeach airson stealladh no clàran B12
Choose injections when risk is high or oral reliability is low; choose high-dose tablets when deficiency is mild-to-moderate, intake is the main issue and follow-up is dependable. The best route is the one that corrects deficiency without postponing investigation of its cause.
Tablets fit best when B12 is low from diet, there are no neurological signs, swallowing is safe and the person can take 1,000-2,000 micrograms daily consistently. Injections fit best with neurological findings, severe symptomatic anemia, vomiting, major malabsorption, post-operative anatomy or uncertain adherence.
Bring four things to the appointment: the original B12 result with units, a CBC, every supplement and medicine dose, and a symptom timeline. Dr. Thomas Klein’s clinical rule is that the cause should be named before maintenance is made indefinite whenever that can be done safely.

Ceistean Bitheanta
A bheil in-stealladh B12 nas luaithe na tablaidean?
Tha stealladh B12 a’ togail serum B12 nas luaithe na clàran leis gu bheil dòs 1,000 microgram a-steach don fhèith a’ seachnadh gabhail a-steach caolain agus faodaidh e ìrean cuairteachaidh àrdachadh taobh a-staigh uairean. Faodaidh B12 beòil le dòs àrd, mar as trice 1,000-2,000 microgram a h-uile latha, easbhaidh a cheartachadh gu h-èifeachdach thar grunn sheachdainean ann am mòran de dh’inbhich. Is e na puingean stad cudromach a bhith a’ leasachadh chomharran, reticulocytes ron latha 3-5 agus slànachadh CBC timcheall air 4-8 seachdainean, chan ann a-mhàin am mullach serum sa bhad. Is fheàrr le stealladh nuair a tha comharran nèamhach, anemia trom no gabhail a-steach neo-earbsach an làthair.
An urrainn do B12 beòil obrachadh ma tha anemia pernicious agam?
Faodaidh B12 beòil aig dòs àrd obrachadh ann an cuid de dhaoine le ana-mionn pernicious oir tha mu 1% de dhaoine a’ gabhail a-steach dòs mhòr tro sgaoileadh fulangach gun phrionnsapal. Mar sin, faodaidh dòs bheòil 1,000-2,000 microgram gach latha 10-20 microgram de B12 a ghabhail a-steach, a tha nas àirde na an ìre làitheil a dh’ fheumas inbheach de 2.4 microgram. Bidh stiùireadh NICE gu tric a’ toirt taic do ath-nuadhachadh intramuscular fad-beatha airson gastritis fèin-dìonach, gu sònraichte far a bheil earbsa neo-chinnteach. Bu chòir an t-slighe aontachadh leis an dotair a tha a’ riaghladh an diagnosis agus a’ cumail sùil air le comharraidhean agus CBC.
Cia mheud clàr B12 a tha co-ionann ri aon stealladh?
Chan eil atharrachadh cinnteach bho chaochladh gu stealladh leis gu bheil stealladh a' toirt prìomh-làn ruigsinneachd siostamach fhad 'sa tha gabhail beòil an crochadh air an dòs agus tha e gu ìre làn-fhillte. Tha stealladh 1,000 microgram agus 1,000-2,000 microgram beòil gach latha nan dòsan leigheis cumanta, ach chan eil iad eadar-ghluasadach gu cungaidhean-leigheis air bunait dòs-air-dòs. Mu 1% de 1,000 microgram de dhòs beòil faodaidh e a dhol a-steach tro dhlùthachadh fulangach, fhad ‘s a tha gabhail a bharrachd a’ tachairt tro fhactar a-staigh nuair a tha an t-slighe sin ag obair. Bu chòir freagairt leigheis agus adhbhar an easbhaidh stiùireadh sam bith atharrachadh.
Dè cho fada a bheir e air in-stealladh B12 leasachadh a thoirt air sgìths?
Faodaidh stealladh B12 lùth a leasachadh taobh a-staigh làithean gu beagan sheachdainean nuair is e dìth an fhìor adhbhar airson sgìths, ach tha an ùine ag atharrachadh gu mòr. Bidh cinneasachadh reticulocytes gu tric ag èirigh ro là 3-5, bidh hemoglobin gu cumanta a’ tòiseachadh ag èirigh às deidh 1-2 sheachdain, agus faodaidh làn cheartachadh air macrocytosis suas ri 8 seachdainean a thoirt. Tha numbness, trioblaidean cothromachaidh agus comharran cognitive gu tric a’ toirt 3-12 mìosan agus faodaidh iad a bhith neo-iomlan ma bha an dìth fada. Bu chòir ath-sgrùdadh airson dìth iarainn, tinneas thyroid, trioblaidean cadail agus adhbharan eile a bhrosnachadh le sgìths leantainneach às deidh CBC àbhaisteach.
Am bu chòir dhomh clàran B12 a ghabhail ro dheuchainn fala?
Ma tha deuchainn air a phlanadh gus dìth B12 neo-mhìneachail a dhearbhadh agus a bheil thu gu clionaigeach seasmhach, seachain tòiseachadh air stuthan cur-ris gus an tèid an sampall a chruinneachadh oir faodaidh eadhon 50-500 microgram gach latha serum B12 atharrachadh. Chan eil ùine nighe cruinne ann, leis gu bheil obair-lann agus dòsan eadar-dhealaichte, mar sin faighnich don dotair no don obair-lann airson an comhairle ullachaidh aca. Na cuir dàil air làimhseachadh gus làn bhunait fhaighinn ma tha comharraidhean eanchainn ort, anemia trom, dragh co-cheangailte ri torrachas no crìonadh clionaigeach mòr. Clàraich an dòs agus an ceann-latha tòiseachaidh gus an gabh an toradh a mhìneachadh gu ceart.
A bheil ìre B12 de 200 pg/mL ìosal gu leòr airson stealladh?
Tha ìre B12 de 200 pg/mL aig a bheil crìoch ìosal agus chan eil e leis fhèin a’ dearbhadh a bheil feum air in-stealladh. Tha mòran deuchainn-lannan a’ beachdachadh air luachan fo 180 pg/mL gu soilleir neo-ghlan, fhad ‘s a dh’ fhaodadh gum bi feum aig luachan bho timcheall air 180-350 pg/mL air searbhag methylmalonic, homocysteine, toraidhean CBC agus ath-sgrùdadh comharraidhean. Tha in-stealladh reusanta aig 200 pg/mL nuair a tha comharran nèamhach, anemia, malabsorption, torrachas no neo-chomasachd air cungaidhean beòil a ghabhail an làthair. Faodaidh neach seasmhach le cunnart daithead agus gun lorg nèamhach freagairt gu math ri 1,000-2,000 micrograman B12 beòil gach latha le leantainn clàraichte.
