Vitamin B12 Test & IV Therapy in London

Author: Mr Tharb Faisl & Dr Caplin Merijo

Constant Fatigue? It Might Be a Vitamin B12 Deficiency

Do you feel constantly tired, unfocused, or experience tingling in your hands and feet?

These are all classic signs of vitamin B12 deficiency, which affects thousands in the UK — especially vegans, vegetarians, and people with digestive issues.

At Marylebone Diagnostic Centre, we offer a private vitamin B12 blood test, followed by rapid, restorative B12 IV therapy if needed.

Why Choose a Private Vitamin B12 Blood Test?

A private vitamin B12 blood test checks your blood for optimal B12 levels, along with:

• Folate
• Ferritin (Iron)
• Vitamin D (optional add-on)
• Full Blood Count (to check red blood cell health)

You’ll get results in 1–2 working days, clearly explained with no medical jargon.

Symptoms of Vitamin B12 Deficiency

Many people come to us with:

• Ongoing fatigue or weakness
• Brain fog or trouble concentrating
• Tingling or pins and needles
• Pale skin or shortness of breath
• Low mood, irritability, or anxiety
• Mouth ulcers or sore tongue

Untreated, B12 deficiency may lead to nerve damage and long-term exhaustion — making early testing essential.

Fast-Acting IV Therapy for B12 Deficiency

Once your private vitamin B12 blood test confirms low levels, we offer high-strength B12 IV therapy using methylcobalamin — the most bioavailable form.

Better Than Over-the-Counter: Here’s Why

Many patients try oral supplements, but they may not absorb properly due to gut conditions. IV therapy skips the digestive tract entirely — giving you faster, longer-lasting results.

Our private vitamin B12 blood test + IV combo mirrors top London wellness brands like REVIV and Get A Drip — but with medical oversight, pre-treatment testing, and tailored care.
