                                According to a 2022 UK survey, approximately 4 out of 10 patients with a B12 deficiency self-medicate via injection, often due to feeling underserved by their general practice. While this practice is possible and can be convenient for those with a medical need, it is not a decision to be taken lightly and requires a strict adherence to safety protocols and medical guidance.
