Vitamin B12 Injections: Support Your Health and Wellbeing

Vitamin B12 is an essential nutrient that helps your body produce healthy red blood cells, maintain a healthy nervous system and release energy from food. If your vitamin B12 levels are low, you may experience tiredness, weakness, difficulty concentrating and other symptoms that can affect your everyday life.

Our pharmacy’s Vitamin B12 injection service offers professional advice and assessment to help determine whether treatment is appropriate for you. If you are concerned about low vitamin B12 levels, our pharmacy team can discuss your symptoms, explain the available options and advise you on the most suitable next steps.

What is a Vitamin B12 injection?

A Vitamin B12 injection delivers vitamin B12 directly into a muscle, allowing it to be absorbed into the bloodstream.

Injections may be recommended for people with a confirmed deficiency, including those whose vitamin B12 levels are low because of certain medical conditions or problems with absorption.

How does the Vitamin B12 injection service work?

Our pharmacy aims to make accessing advice about vitamin B12 straightforward and convenient.

1. Initial consultation

We discuss your symptoms, general health, medical history, diet and any concerns you may have about vitamin B12 deficiency.

2. Assessment and suitability

We consider whether an injection service is appropriate for you. Where necessary, we may recommend a blood test or consultation with your GP to establish whether you have a deficiency and identify its underlying cause.

3. Treatment advice

If treatment is appropriate, we explain the available options and whether a Vitamin B12 injection can be provided through our service. Injections should only be administered when clinically appropriate and in accordance with the relevant prescribing and supply requirements.

4. Ongoing guidance

We can advise you on follow-up care and when further assessment may be needed. People with an ongoing cause of vitamin B12 deficiency may require regular treatment and monitoring.

Please note: Vitamin B12 injections are not suitable for everyone. A consultation does not automatically mean that an injection will be provided, and some people will need blood tests or medical assessment before treatment.

What are the main causes of vitamin B12 deficiency?

Vitamin B12 deficiency can develop for several reasons. Identifying the cause is important because it helps determine the most effective treatment and whether ongoing supplementation is necessary.

Common causes include:

Insufficient dietary intake: Vitamin B12 is found naturally in foods such as meat, fish, eggs and dairy products. People following a vegan diet, or a diet containing very few B12-rich foods, may be at increased risk if they do not obtain enough from fortified foods or supplements.
Pernicious anaemia: An autoimmune condition that affects the body’s ability to absorb vitamin B12. It is an important cause of deficiency and often requires long-term treatment.
Digestive conditions: Conditions affecting the stomach or small intestine, including some cases of coeliac disease and Crohn’s disease, can interfere with vitamin B12 absorption.
Stomach or intestinal surgery: Procedures that remove or alter parts of the digestive system can reduce the body’s ability to absorb vitamin B12.
Certain medicines: Long-term use of some medicines, including metformin and proton pump inhibitors, can contribute to low vitamin B12 levels in some people.
Age-related changes: Some older adults absorb vitamin B12 less efficiently because of changes in stomach function.

If you suspect you have a deficiency, it is important to establish the underlying cause rather than relying on injections or supplements without appropriate assessment.

What is the role of vitamin B12?

Vitamin B12 plays several essential roles in keeping your body functioning properly.

Red blood cell production

Vitamin B12 helps your body produce healthy red blood cells, which carry oxygen around the body. A deficiency can lead to megaloblastic anaemia, a condition in which red blood cells become abnormally large and do not function properly.

Nervous system health

Vitamin B12 helps maintain the protective covering around nerves and supports normal nerve function. Low levels can cause tingling, numbness, balance problems and other neurological symptoms.

Energy metabolism

Vitamin B12 helps your body process nutrients and release energy from food. Although it is essential for normal energy metabolism, taking extra B12 will not necessarily improve energy levels if your vitamin B12 levels are already adequate.

Brain function and psychological wellbeing

Vitamin B12 is important for normal brain and nervous system function. Deficiency can sometimes contribute to memory difficulties, problems with concentration and changes in mood.

DNA production

Vitamin B12 is required for DNA synthesis, which is essential for normal cell growth and the production of new cells.

Maintaining adequate vitamin B12 levels is therefore important for your blood, nerves and overall health.

What are the symptoms of low vitamin B12?

Vitamin B12 deficiency can develop gradually, and symptoms may initially be subtle. Some people experience several symptoms, while others may have few noticeable signs.

Possible symptoms include:

Persistent tiredness or fatigue.
Weakness or a lack of energy.
Pale skin.
Breathlessness, particularly during physical activity.
Headaches, dizziness or light-headedness.
A sore, red tongue or mouth ulcers.
Pins and needles or numbness in the hands and feet.
Muscle weakness or difficulty with balance and coordination.
Problems with memory, concentration or thinking clearly.
Changes in mood, including low mood or irritability.
Visual disturbances in some cases.

Not everyone with these symptoms has a vitamin B12 deficiency, as they can also be associated with other health conditions. A blood test and appropriate clinical assessment can help identify the cause.
