Our most-booked shot, and the one where knowing your actual B12 status makes the biggest difference. Fifteen minutes, in and out — and worth pairing with a blood test if you have never had one.
What's available
Members receive four to six free B12 shots every month depending on plan.
At a glance
A plain description of what is in the bag and what happens while you are here.
Injection sidesteps the intrinsic-factor pathway entirely, which is the whole point when absorption is the limiting problem.
B12 is required for normal erythropoiesis and DNA synthesis.
B12 maintains the myelin sheath; neurological symptoms are a recognised feature of deficiency.
Genuinely quick, and easy to add to any drip visit.
The science
We would rather tell you where the evidence is strong, where it is thin, and where it simply does not exist yet.
Dietary B12 requires gastric acid, then intrinsic factor from stomach parietal cells, for receptor-mediated absorption in the distal ileum. That pathway saturates: oral absorption is around 50% at 1-2 mcg doses but only about 1.3% at 1,000 mcg. Injection bypasses it entirely.
A minor passive-diffusion route of roughly 1% explains why high-dose oral B12 can work for many people, and trials generally find high-dose oral comparable to injection for uncomplicated deficiency. Injection's real advantage is in malabsorption — which is a reason to find out which situation you are in.
Neurological signs such as numbness, tingling, or changes in gait or memory can occur without anaemia. Body stores of 1-5mg mean symptoms may take years to appear.
NIH ODS states that B12 'appears to have no beneficial effect on performance in the absence of a nutritional deficit.' If your B12 is normal, do not expect a lift. If it is low, correcting it can matter a great deal. Also worth knowing: there is no evidence that absorption differs between methylcobalamin and cyanocobalamin.
Who commonly considers this: People with confirmed or suspected low B12 — vegans and vegetarians, adults on long-term metformin or acid-reducing medication, people with pernicious anaemia, atrophic gastritis or bariatric surgery history, and older adults.
