A B12 injection delivers a measured dose of vitamin B12, in the form of cyanocobalamin, directly into the muscle, usually the upper outer arm. Vitamin B12 is essential for red blood cell production, nerve function, energy metabolism and the synthesis of DNA. When given by intramuscular injection, the dose bypasses the digestive tract and is absorbed reliably, which matters because dietary B12 absorption depends on stomach acid and a protein called intrinsic factor, both of which decline with age, medication and certain gut conditions. The injection itself takes around ten seconds and the full appointment is under fifteen minutes.

B12 injections suit vegetarians and vegans who do not eat animal foods, patients with confirmed absorption issues such as pernicious anaemia, coeliac disease or significant IBS, older adults whose stomach acid has dropped with age, and patients on long-term metformin or proton-pump inhibitors that lower B12 absorption. They also suit anyone whose energy, mood or focus has dipped without an obvious cause and who wants a reliable top-up alongside a balanced diet. Patients with a clinically diagnosed B12 deficiency should be under GP care for ongoing management; we will ask about this at consultation and coordinate with your GP where appropriate.

Most patients notice a lift in energy and mental clarity within two to seven days of the first injection, though the response is more pronounced in patients who were running low to begin with. Some patients feel a difference within twenty-four hours. The effect of a single shot typically lasts four to eight weeks, depending on diet, lifestyle and how depleted you were at the start. For ongoing support a maintenance schedule of one injection every four to twelve weeks is common, agreed at your free consultation.
