The most common signs of vitamin B12 deficiency are tiredness and weakness, numbness and pins and needles, a sore red tongue, and memory or concentration problems. It is diagnosed with a blood test, and a doctor decides the treatment (injections or tablets). If your doctor suggests tablets: the best value is Optimelt B12 (1000 mcg, EGP 100); with folic acid, Speconditional (EGP 120); imported, Jarrow (EGP 1,300 for 100 tablets).
Symptoms of vitamin B12 deficiency
According to the NHS, symptoms usually develop gradually and can get worse if the deficiency is not treated. Some are shared with anaemia, and some neurological ones are specific to B12 deficiency:
| Type | Symptoms |
|---|---|
| General (anaemia) | Tiredness and weakness, shortness of breath, headaches, palpitations, loss of appetite, diarrhoea or indigestion |
| Mouth | A sore, red tongue, sometimes with mouth ulcers |
| Neurological | Numbness, pins and needles, muscle weakness, problems with balance and coordination |
| Mood and memory | Problems with memory, understanding and judgement, mild depression or anxiety, and confusion in severe cases |
| Other | Vision problems and incontinence |
Do not wait
The NHS says some problems caused by B12 deficiency can be permanent if left untreated, and the longer it goes on, the higher the chance of lasting damage. If you have numbness, balance or memory problems, see a doctor early.
Who is at risk of B12 deficiency?
- Pernicious anaemia: an autoimmune condition that stops B12 being absorbed from the stomach; the most common cause in the UK, per the NHS.
- Diet: vegans and people who rarely eat meat, fish or dairy. Body stores can last 2 to 5 years, so symptoms can take a long time to appear.
- Stomach or bowel surgery and conditions: such as removing part of the stomach, or Crohn’s disease.
- Medicines: stomach-acid reducers (PPIs) and the diabetes medicine metformin can lower B12 levels, per the NHS.
Adults need only about 1.5 micrograms of B12 a day (per the NHS), from meat, fish, milk, cheese and eggs.
Diagnosis and treatment: injections or tablets?
- Tests: per Cleveland Clinic, a complete blood count (CBC), a vitamin B12 level, and sometimes methylmalonic acid (MMA) and homocysteine tests.
- Injections: the NHS says injections are the usual treatment, especially when the cause is not diet (such as pernicious anaemia), and they may be needed for life.
- Tablets: mainly used when the deficiency is caused by diet; the NHS says to take them daily between meals.
- Vegans: may need B12 tablets for life.

How to take a B12 supplement properly
- Test first: the symptoms overlap with many other conditions, and a blood test confirms the deficiency and guides treatment.
- Tablets between meals: as the NHS advises if your doctor prescribes tablets.
- Dose: the NHS says up to 2 mg (2,000 mcg) a day from supplements is unlikely to cause harm; every tablet here is 1000 mcg.
- Sublingual tablets: let the tablet dissolve under your tongue rather than swallowing it.
- If you take a multivitamin: count the B12 and folic acid in it. See our multivitamin guide.
Common mistakes
- Supplementing without a test: it can delay the diagnosis of pernicious anaemia, which needs injections.
- High-dose folic acid on its own: the NHS says more than 1 mg a day can mask the symptoms of B12 deficiency.
- Stopping injections without a doctor: if the cause is not diet, treatment is often ongoing.
- Assuming tiredness is always B12: tiredness has many causes, such as iron deficiency and thyroid problems.
Important safety notes
- If you have neurological symptoms (numbness, balance or memory problems), see a doctor promptly; you may need injections and a haematologist, per the NHS.
- If you take metformin or acid reducers long term, ask your doctor about a B12 test.
- Pregnancy: a doctor should set the folic acid dose, so do not take a high-folic-acid supplement without asking.
- These are food supplements, not treatments, and they do not replace medical follow-up.
