The 2024 NICE NG239 guideline on vitamin B12 deficiency in over-16s lists the main groups who need injections: Autoimmune gastritis (pernicious anaemia)
Because B12 is water-solublemeaning your body uses what it needs and flushes out the restyour dosage and injection frequency depend heavily on your starting levels and your specific wellness goals
Foods high in B12 include fish, meat, poultry, eggs, dairy produce, and foods that are fortified with B12 (like some breakfast cereals.) If you follow a restrictive diet or have a condition that impacts absorption, you could be at risk for a B12 deficiency
