“At first, you’ll have these injections every other day for two weeks or until your symptoms have started improving,” explains the NHS.
The health site adds: “After this initial period, your treatment will depend on whether the cause of your vitamin B12 deficiency is related to your diet or whether the deficiency is causing any neurological problems, such as problems with thinking, memory and behaviour.”
If your vitamin B12 deficiency is caused by a lack of the vitamin in your diet, you may be prescribed vitamin B12 tablets to take every day between meals.
Reasons for not getting enough of it in your diet
People following a vegetarian or vegan diet are at a far greater risk of developing B12 deficiency because the vitamin is mainly found in meat, fish, milk and other dairy products.
