First-time? A short medical history conversation comes first — usually 10 minutes — before any injection. If you have a confirmed B12 deficiency on recent bloods, bring those.

The science, plainly

What it actually does.

Vitamin B12 (cobalamin) is essential for red blood cell formation, neurological function, and energy metabolism. Most people get it from food — meat, eggs, dairy. Some people don’t absorb it well from food (vegans, people with absorption disorders, older adults, people on certain medications including metformin and some heartburn drugs).

An intramuscular injection bypasses the absorption step entirely. The B12 goes directly into muscle tissue, releases into the bloodstream over hours to days, and is used by your body without depending on your gut to process it.

For people with confirmed B12 deficiency, this is the gold-standard route — faster and more reliable than oral supplements. For people with low-normal B12 levels who are experiencing fatigue, brain fog or low energy, an injection course can help with symptoms while you investigate the underlying cause.

An injection is not a substitute for medical investigation if you’re feeling persistently fatigued. If your symptoms are significant, see your GP for bloods first — you may have a deficiency that warrants a longer-term plan, or another cause that injections won’t address.

Common questions

Good to know.

How often should I have B12?
Depends on your levels. For diagnosed deficiency, your GP usually sets a schedule (often 3-monthly long-term). For low-normal levels with symptoms, a course of 4 over 4 weeks then a top-up every 1-3 months is typical. We agree the cadence at consultation.
Are vitamin injections safe?
B12 specifically has an excellent safety profile. It’s water-soluble — your body excretes excess via urine. Allergic reactions are rare but possible. I’ll take a full history before any first injection.
Will I feel a difference?
If you’re actually deficient, often yes — some clients notice an energy lift within days. If your B12 is normal, the placebo response is real but the physiological benefit isn’t. I’ll be honest about whether I think it’ll help you.
Should I get bloods first?
Ideally, yes. If you’ve got recent bloods showing your B12 level, bring them. If you don’t but you’ve got specific risk factors (vegan, over 60, on metformin) we can usually proceed. If you’ve got persistent unexplained fatigue, see your GP for bloods first — there might be more going on.
Where does the injection go?
Intramuscular — usually in the upper arm (deltoid) or upper outer thigh. Quick scratch, over in seconds. No real downtime.
Will it hurt?
Brief sharp scratch, then mild pressure as the medicine goes in. Most clients describe it as one of the easiest injections they’ve had. Mild soreness at the site for a day is normal.
What about other vitamin injections (vitamin D, glutathione, fat burners)?
B12 is the only vitamin injection I currently offer. Other intramuscular vitamin protocols exist but I don’t prescribe them as I’m cautious about evidence base for marketing them as wellness treatments. If you’ve got a specific clinical need, see your GP.
Can I have B12 if I’m pregnant?
B12 is safe in pregnancy and many pregnant women are advised to supplement. But during pregnancy this should be coordinated with your midwife or GP rather than as a one-off cosmetic-style injection.
I’m vegan — do I need this?
Possibly. Vegans don’t get B12 from food (it’s only naturally present in animal products). Most vegans take an oral B12 supplement, which is usually enough. If your levels are low despite supplementing, or you don’t supplement reliably, an injection course can help.
What if I have a fish or shellfish allergy?
Not relevant for B12 specifically — the products we use don’t contain fish-derived components. Always declare allergies on the medical questionnaire.
