Vitamin B12 is an essential vitamin that helps your body produce healthy red blood cells, maintain a healthy nervous system, and support normal energy metabolism. Because the body cannot produce Vitamin B12 on its own, it must be obtained through diet or supplementation.

A Vitamin B12 injection delivers hydroxocobalamin directly into the muscle, allowing the vitamin to be absorbed into the bloodstream without relying on the digestive system. B12 injections are commonly used for people with Vitamin B12 deficiency or those who have difficulty absorbing B12 through food or oral supplements.

Vitamin B12 deficiency can cause a variety of symptoms, including:
Persistent tiredness or fatigue.
Low energy levels.
Brain fog or difficulty concentrating.
Pins and needles.
Numbness in the hands or feet.
Dizziness.
Breathlessness.
Low mood.
Memory difficulties.
These symptoms can also be caused by other medical conditions, so professional assessment is important.

People at increased risk include:
Vegetarians and vegans.
Adults over 50 years of age.
Individuals with Crohn’s disease or coeliac disease.
People with certain stomach or bowel conditions.
Those who have had gastrointestinal surgery.
People taking certain medications that can affect B12 absorption such as omeprazole and metformin

A blood test is often the most reliable way to identify Vitamin B12 deficiency. If you have recent blood test results, our clinician may review them during your consultation.
If you have symptoms suggestive of Vitamin B12 deficiency but have not been tested for it you may still be eligible for the B12 injection. Our clinicians will help you assess your suitability.

Vitamin B12 deficiency can cause fatigue and low energy levels. For individuals whose symptoms are related to low Vitamin B12 levels, treatment may help correct the deficiency.
However, fatigue can have many causes, and a B12 injection may not be appropriate for everyone experiencing tiredness. Our clinicians can help you determine the cause of your fatigue.

Vitamin B12 tablets are absorbed through the digestive system, whereas B12 injections deliver the vitamin directly into the muscle for absorption into the bloodstream.
For individuals with absorption difficulties, digestive conditions, or diagnosed deficiency, injections may be more appropriate than oral supplements.

The response to Vitamin B12 injections varies between individuals. Some people notice improvements in symptoms relatively quickly, while others may require several days or weeks before experiencing benefits.
The speed and extent of improvement often depend on the underlying cause and severity of the deficiency.

The recommended frequency depends on the cause of your Vitamin B12 deficiency and your individual circumstances.
If your low Vitamin B12 levels are due to a dietary deficiency, injections are often given every 6 months. If the cause is pernicious anaemia, injections are typically required every 2 to 3 months to maintain adequate Vitamin B12 levels.
Our clinician will assess your situation and advise on the most appropriate treatment schedule for you.

Side effects are usually mild and temporary. Some people experience:
Mild pain or redness at the injection site.
Headache.
Dizziness.
Nausea.
Serious reactions are rare, but you should seek medical advice if you experience any unexpected symptoms after treatment.
