Good to know
Questions, answered.
Who benefits from B12 injections?
People with B12 deficiency, vegetarians and vegans, those with absorption issues (Crohn's, coeliac, post-bariatric), anyone on metformin long-term, and people experiencing unexplained fatigue or brain fog.
How often do I need an injection?
Initially more frequent (weekly or fortnightly) to load. Maintenance is usually monthly or every 2–3 months once levels are stable.
Are there any side effects?
Generally very safe. You may notice mild soreness at the injection site, occasional mild nausea or brief dizziness. Serious side effects are rare.
Does the injection hurt?
Virtually painless. It's a small intramuscular shot in the upper arm — most people are surprised at how brief it is.
Will I notice a difference straight away?
Some people feel sharper within days, others notice it over 1–2 weeks. If you've been deficient for a while, allow a full course to see the full effect.
How much does a B12 injection cost?
£35 for a single injection. A course of 3 is £90 and a course of 6 is £170.
Can I get B12 injections on the NHS?
If you have a diagnosed B12 deficiency, such as pernicious anaemia, your GP may prescribe injections on the NHS. Our private injections are an option if you're not eligible or prefer the convenience.
Is there anyone who shouldn't have one?
Tell us about any allergies, medical conditions and medicines you take. We check the injection is suitable for you before we give it.
