About this treatment
What it does
Vitamin B12 is one of the small handful of nutrients your body cannot make on its own. It plays a central role in red blood cell formation, energy production, nervous system function, and mood regulation — and when levels run low, the symptoms tend to be vague enough that people put up with them for years before realising what's wrong.
An injection delivers B12 directly into the muscle, bypassing the digestive system entirely. For those who absorb it poorly from food (which is more common than people realise — particularly with age, certain medications, or vegetarian and vegan diets), this is far more reliable than oral supplements.
Most clients describe a noticeable lift in energy, focus, and general sense of steadiness within a few days. We offer this as a standalone treatment or as part of a maintenance routine every 4-12 weeks.
The Journey
Quick, simple, and over before you know it
- 01
Brief Consultation
A short conversation about your symptoms, diet, and any relevant medical history. We'll ask about previous B12 levels if you've been tested, and confirm there's no reason the injection wouldn't be appropriate. Walk-ins are welcome subject to availability.
- 02
Injection
The injection is given into the upper arm muscle. It takes seconds. Most clients describe it as a brief sting, no worse than a routine vaccination — and it's over before you've finished thinking about it.
- 03
Effects
No downtime. You can drive, return to work, or carry on with your day immediately. Most clients begin to notice a difference within 24-72 hours, with the full benefit settling over the first week. Top-ups every 4-12 weeks for ongoing support.
The Details
What to expect
Aftercare in brief
After your injection
Mild soreness or a small bruise at the injection site is normal and usually resolves within 24-48 hours. You can shower and exercise as normal — there are no restrictions. Drink plenty of water for the first 24 hours. If you experience any unusual symptoms, contact us immediately.
Common Questions
You asked, we answered
Do I actually need a B12 injection?
Possibly, possibly not. Common signs of low B12 include persistent fatigue, brain fog, low mood, tingling in the hands or feet, and pale skin. People most likely to benefit are vegetarians and vegans, those over 50, anyone on long-term acid-reducing or diabetes medication, and people recovering from illness. If you're symptom-free and eat a varied diet, your levels are likely fine — and we'll tell you so.
How quickly will I feel a difference?
Most clients notice a lift in energy and focus within 24-72 hours, with the full benefit settling over the first week. If you've been significantly deficient, the change can be quite striking. If your levels were only mildly low, the change is more subtle.
How often should I have one?
It depends on why you're having them. For maintenance, every 4-12 weeks is typical — most clients land somewhere around every 8 weeks. For people with absorption issues or recovering from a deficiency, more frequent top-ups in the first few months can be helpful. We'll discuss what suits you at consultation.
Is it the same as the B12 my GP gives?
The active ingredient is the same — methylcobalamin or hydroxocobalamin, depending on the product. The difference is access. NHS B12 injections are typically reserved for diagnosed deficiency. If you have symptoms but haven't reached the threshold for prescription, or you simply prefer not to wait for an appointment, this offers a faster route.
Can I just take a tablet instead?
You can, and for some people that's enough. But B12 absorption from oral supplements relies on a specific protein in the stomach (intrinsic factor), and many people — particularly older adults and those on certain medications — don't produce enough of it. Injections bypass that step entirely, which is why they tend to be more reliably effective.
Are there any side effects?
Side effects are uncommon and usually mild — a small bruise at the injection site, mild soreness, occasionally a brief headache. Allergic reactions are very rare. We'll go through your medical history at consultation and decline treatment if there's any reason it isn't safe for you.
Can I have it if I'm pregnant or breastfeeding?
B12 injections can be safe during pregnancy and breastfeeding when clinically indicated, but we'd want you to discuss it with your GP or midwife first. Please don't book without that conversation — bring evidence of their guidance to your consultation.
