Vitamin B12 Injections at Renu Medical Aesthetics "Energy, Immunity & Mental Clarity Boost"

Vitamin b12 injections

Feel Refreshed, Revitalised, and Ready to Go

What Is Vitamin B12 and Why Is It Important?


Vitamin B12 plays a key role in:

  • Red blood cell production
  • Brain and nervous system health
  • Energy metabolism
  • Immune function 
  • Reducing fatigue and mental fog
     

Deficiency is common — especially among those with restrictive diets, digestive conditions, or high stress levels.



Benefits of Vitamin B12 Injections


✔️ Increased energy and reduced fatigue
✔️ Improved mood, focus, and mental clarity
✔️ Enhanced immunity and metabolism
✔️ Support for stress, burnout, or busy lifestyles
✔️ Fast, doctor-administered treatment with no downtime



Who Is This Treatment For?


You may benefit from a B12 injection if you:


  • Feel constantly tired or sluggish
  • Experience frequent low mood or poor concentration
  • Follow a vegetarian or vegan diet
  • Are recovering from illness, stress or burnout
  • Want a general wellness boost
     


 

Can B12 Help with Metabolism and Weight Loss?


Vitamin B12 plays a key role in how your body uses energy — it helps convert the food you eat into glucose, which your cells use for fuel. Because of this, it’s often linked to energy production, metabolism, and even fat and carbohydrate processing.


While B12 isn’t a weight-loss injection on its own, it can help support energy, focus, and metabolic function — all of which are helpful if you’re trying to lose weight or feel better day-to-day.



What to Expect


1. Consultation
We’ll assess whether a B12 injection is right for you and explain the benefits clearly.


2. Treatment
A quick injection into the upper arm or top of your leg — takes just a few seconds.


3. Results
Many clients report feeling more energised and focused within 24–72 hours. A course of regular injections may offer longer-lasting benefits.



Pricing


Single B12 Injection – £30


Course of 4 Injections (weekly or fortnightly) – £100


 Feel Like Yourself Again – Naturally 


 If you're tired of feeling tired, B12 injections could help restore your energy, focus, and vitality — safely and quickly.

Why Choose a Course of Vitamin B12 Injections?

A one-off B12 injection can give you a quick lift in energy and focus — but if you're experiencing ongoing fatigue, low mood, or stress, a course of regular treatments offers deeper and more sustained benefits.


Here’s why:


  • Builds and maintains B12 levels in the body over time
     
  • Supports consistent energy, mood, and focus rather than short spikes
     
  • Enhances brain, nerve, and immune health with cumulative support
     
  • Ideal for those with long-term low levels, dietary gaps, or busy lifestyles
     

Most clients feel best with a course of 4 injections over 4–6 weeks, followed by occasional top-ups if needed.

Vitamin b12 treatment FAQs

 This depends on your needs and whether you have a diagnosed deficiency. Some clients have them every 2–4 weeks; others just as a one-off boost.



Side effects are rare. You may have mild redness at the injection site. Dr Jackie will discuss any risks during your consultation.


Vitamin B12 won’t directly burn fat, but it can support your metabolism, energy levels, and motivation — all of which can help with weight loss.


If you’re feeling sluggish, low in mood, or struggling to stay active, correcting a B12 deficiency may help you get back on track.


It can also be a helpful support alongside structured weight loss plans. 


Yes — many clients combine B12 with weight loss, skin boosters, or wellness treatments for a holistic boost 


 Not always. We can discuss your symptoms, history, and goals during your consultation to determine if a B12 injection is suitable for you.  


 These don’t necessarily rule out treatment but warrant discussion and monitoring:

  • Leber’s Disease (hereditary optic nerve atrophy):
    B12 can accelerate optic nerve damage in these rare cases. 
  • Polycythemia vera:
    B12 may stimulate red blood cell production, so this should be monitored in people with this condition. 
  • Uncontrolled hypokalaemia (low potassium levels):
    Rapid correction of B12 deficiency can worsen this — though it's rare, it should be watched in known cases.
  • Folic acid deficiency:
    B12 can mask folate deficiency, so both should be assessed if deficiency is suspected.
  • Pregnancy/Breastfeeding:
    B12 is usually considered safe, but always document and dose according to guidelines.
     


“I didn’t realise how flat and foggy I’d been feeling until after my B12 injection — within a couple of days I had more energy, clearer focus, and felt like myself again. It’s now part of my regular self-care.”
