Vitamin B12 injection

A Vitamin B12 injection is an intramuscular treatment designed to replenish low Vitamin B12 levels. Each ampoule contains 3 mL and is administered by a qualified healthcare professional following a consultation and medical assessment.

Vitamin B12 supports red blood cell production, normal nerve function and several processes involved in energy production.

A Vitamin B12 injection may be suitable for adults with a confirmed low Vitamin B12 level, particularly those with a blood level below 150 pg/mL.

It may also be considered for individuals experiencing symptoms or risk factors associated with Vitamin B12 deficiency, such as:

• Persistent tiredness or low energy
• Poor concentration or brain fog
• Numbness or tingling in the hands or feet
• Muscle weakness
• Pale skin
• A vegan or highly restricted diet
• Medical conditions that affect nutrient absorption
• Long-term use of certain medications, including metformin or acid-reducing medicines

Final eligibility depends on your blood test results, symptoms, medical history and the healthcare professional’s assessment.

Valeo’s Vitamin B12 injection service may be considered for individuals with a confirmed low Vitamin B12 level.

For Vitamin B12 levels below 150 pg/mL, Valeo offers a Deficiency Recovery Pack consisting of five injections administered 10 days apart, subject to consultation and clinical approval.

Laboratory reference ranges may vary, so your result should always be interpreted together with your symptoms, medical history and other relevant blood test results.

The Vitamin B12 injection is administered intramuscularly, meaning it is injected into a suitable muscle.

Depending on the medication, volume and the healthcare professional’s assessment, the injection may be administered into a muscle in areas such as the upper arm, thigh or hip area.

The healthcare professional will select the safest and most appropriate injection site for you.

The Vitamin B12 injection is formulated for intramuscular administration. Muscle tissue has a good blood supply, allowing the medication to be absorbed into the bloodstream after it has been administered.

The muscle does not activate the Vitamin B12. Instead, the intramuscular route allows the medication to bypass the digestive system, which may be useful for people who have difficulty absorbing Vitamin B12 from food or oral supplements.

The injection must be administered using the correct technique by a qualified healthcare professional. It should not be self-administered or injected directly into a vein unless specifically prescribed and administered for that purpose.

When a person has low Vitamin B12 levels, correcting the deficiency may help:

• Improve deficiency-related tiredness and low energy
• Support focus and concentration
• Support healthy nerve function
• Support normal red blood cell production
• Improve deficiency-related weakness
• Support overall wellbeing

Vitamin B12 injections are not general energy boosters for everyone. The benefits are most relevant when symptoms are caused by a confirmed Vitamin B12 deficiency.

Yes, a recent blood test is recommended to measure your Vitamin B12 level and help determine whether an injection is appropriate.

Depending on your results and symptoms, the healthcare professional may also review other markers, such as:

• Complete blood count
• Haemoglobin
• Folate
• Iron or ferritin
• Methylmalonic acid or homocysteine, when clinically required

Blood test results should be assessed together with your symptoms because some people may experience deficiency symptoms even when their Vitamin B12 result is close to the laboratory reference range.

The medication starts working after it is administered, but the time needed to notice an improvement varies.

Some individuals may notice an improvement in energy or other symptoms within a few days, while others may require several weeks. Recovery can depend on:

• How low the Vitamin B12 level is
• How long the deficiency has been present
• The cause of the deficiency
• Whether anaemia or neurological symptoms are present
• The recommended treatment schedule

Nerve-related symptoms may take longer to improve and should be assessed promptly by a doctor.

The number and frequency of injections depend on your Vitamin B12 level, symptoms, medical history and the underlying cause of the deficiency.

For Vitamin B12 levels below 150 pg/mL, Valeo’s Deficiency Recovery Pack includes five injections administered 10 days apart, subject to healthcare-professional approval.

Some people may only require a short recovery course, while those with ongoing absorption problems or certain medical conditions may require longer-term treatment. Your schedule should not be repeated or changed without medical advice.

Vitamin B12 injections are generally safe when administered by a healthcare professional. Possible side effects include injection-site discomfort, headache, dizziness, nausea, or mild skin reactions. Consult a doctor if you have allergies, medical conditions, are pregnant/breastfeeding, or take medications that may interact. Seek urgent care for signs of a serious allergic reaction.
