In the UK, vitamin B12 deficiency is relatively common, particularly among older adults, vegans, vegetarians, and individuals with certain gastrointestinal conditions that impair absorption, such as pernicious anaemia or Crohn's disease
The injections themselves only take a few seconds to be administered
