Neurobion combines vitamins B1, B6 and B12. It is taken for nerve-related symptoms such as tingling and numbness, for B-vitamin deficiency, and alongside conditions that deplete these vitamins. The tablet is general sale; there is also an injection, which is prescription-only.
What is Neurobion?
Neurobion is a B-vitamin combination containing:
- Thiamine (vitamin B1)
- Pyridoxine (vitamin B6)
- Cyanocobalamin (vitamin B12)
Check which form you have. The tablet is a Schedule 1 general-sale product. There is also a Neurobion injection, which is Schedule 3 and given by a healthcare professional. They are not interchangeable, and the injection is used in different circumstances.
The three are grouped because each has a distinct role in how nerves function:
- B1 (thiamine) is essential for the nervous system’s energy metabolism. Deficiency causes beriberi and, in alcohol dependence, Wernicke’s encephalopathy — a medical emergency.
- B6 (pyridoxine) is needed to build neurotransmitters and to metabolise amino acids.
- B12 (cyanocobalamin) maintains the myelin sheath, the insulating layer around nerves, and is needed to make red blood cells.
Deficiency in any of them can produce peripheral neuropathy — tingling, numbness, burning or weakness, usually starting in the feet and hands. That shared endpoint is why they are combined in one product.
But the combination is a blunt instrument. If your symptoms come from B12 deficiency, what you need is B12 — and there are two reasons that matters, covered below.
What is Neurobion commonly used for?
- Peripheral neuropathy and nerve symptoms — tingling, numbness, burning, pins and needles.
- Diagnosed B1, B6 or B12 deficiency.
- Diabetic neuropathy, as supportive treatment alongside proper diabetes control.
- Nerve symptoms in alcohol dependence, where B1 deficiency is common and serious.
- Alongside metformin, which reduces B12 absorption over years of use.
- In vegetarian and vegan diets, where B12 comes almost entirely from animal foods.
- After certain gut surgery, or in conditions affecting absorption.
- General tiredness attributed to low B vitamins.
Two cautions about using it for nerve symptoms.
First, B12 deficiency needs diagnosing, not covering. If your symptoms are from B12 deficiency, that has a cause — pernicious anaemia, coeliac disease, long-term metformin or acid-suppressing medicines, gastric surgery, or a strict plant-based diet without supplementation. Finding the cause matters, and severe deficiency may need injections rather than tablets, because the problem is often absorption rather than intake.
Second, taking B vitamins can mask the picture. Folate and B6 can partly correct the blood changes of B12 deficiency while nerve damage quietly continues. That is a recognised trap. Get tested before treating persistent nerve symptoms with a combination supplement.
And nerve symptoms are not always vitamins at all. Diabetes is the commonest cause of peripheral neuropathy. Thyroid disease, kidney disease, nerve compression, HIV, TB medicines and alcohol all cause it too. Several are treatable, and some worsen if missed.
Who commonly looks for Neurobion and why
- People with tingling or numbness in the hands or feet.
- People with diabetes experiencing nerve symptoms.
- People on long-term metformin, where B12 depletion is well recognised.
- People on TB treatment, though isoniazid specifically requires pyridoxine, prescribed at a set amount.
- Vegetarians and vegans, for B12.
- Older adults, in whom B12 absorption declines.
- People with persistent tiredness, hoping a B vitamin will help.
- People taking acid-suppressing medicines long term, which reduce B12 absorption.
What to check on the label before taking Neurobion
Check whether you have the tablet or the injection, and note that the injection is prescription-only.
Check the B6 amount, and add up everything you take. Neurobion contains a substantial amount of pyridoxine. B6 also appears in multivitamins, B-complex products and “nerve” formulas, and sustained high B6 intake causes peripheral neuropathy — the very symptom people take this for. Stacking products is the usual way people reach a harmful total. See Vitamin B6 Pyridoxine for the detail.
Do not take it in addition to a separate B-complex without checking the combined amounts.
Speak to a pharmacist or doctor if:
- Your nerve symptoms are new, worsening or undiagnosed — get them assessed first.
- You have diabetes, so the neuropathy can be properly managed rather than only supplemented.
- You take levodopa for Parkinson’s disease, where B6 can reduce its effect if not combined with carbidopa.
- You take isoniazid — follow the prescribed pyridoxine amount rather than substituting a combination product.
- You take metformin or long-term acid-suppressing medicines, and want B12 checked properly.
- You are pregnant or breastfeeding.
- You have kidney disease.
- You already take a multivitamin or B-complex.
Safety, interactions and when to seek professional advice
The main risk is the B6, taken long term or stacked. High cumulative pyridoxine intake causes sensory nerve damage — numbness, tingling, burning and unsteadiness — which develops over months and may not fully reverse. If nerve symptoms appear or worsen while taking a B6-containing supplement, stop and see a doctor, taking the product with you.
Get B12 measured rather than assumed. A blood test is straightforward, and knowing whether you are deficient changes what you should be taking and whether injections are needed.
B vitamins are not a treatment for diabetes-related nerve damage. Blood sugar control is what slows that, and specific medicines such as amitriptyline or pregabalin treat the pain. A supplement alongside is reasonable; a supplement instead is not.
Harmless-looking urine changes. B vitamins commonly turn urine bright yellow. That is the riboflavin and is not a problem.
Tiredness is rarely just vitamins. Persistent fatigue deserves assessment — anaemia, thyroid disease, diabetes, sleep apnoea and depression are all common and treatable.
Seek medical attention for new, worsening or spreading numbness, tingling or burning; weakness in the hands or feet; unsteadiness on walking; symptoms affecting bladder or bowel control; persistent fatigue that has not been investigated; or nerve symptoms alongside diabetes, alcohol dependence or TB treatment.

Frequently asked questions
What is Neurobion used for? Nerve-related symptoms such as tingling and numbness, and diagnosed B1, B6 or B12 deficiency. It combines vitamins B1, B6 and B12.
What is the difference between the tablet and the injection? The tablet is a general-sale supplement. The injection is a Schedule 3 medicine given by a healthcare professional, used in different circumstances.
Will it help my tingling hands and feet? Only if a B-vitamin deficiency is the cause. Diabetes, thyroid disease, nerve compression and medicines also cause neuropathy, and several are treatable — get it diagnosed.
Can I take it with a B-complex or multivitamin? Check the combined B6 first. Sustained high B6 intake causes nerve damage, and stacking products is how people reach a harmful total.
Should I take it if I am on metformin? Metformin does reduce B12 absorption over time, so it is worth having your B12 measured rather than supplementing blindly.
Why has my urine turned bright yellow? That is normal with B vitamins and is not a cause for concern.
