Vitamin B12 injection Information

While the body doesn't actually create its own vitamin B12, it stores it in the liver for up to five years. But if you have a diet that's chronically deficient in this essential nutrient, you may develop a range of unpleasant symptoms. Fish and meat products are rich in vitamin B12. Eggs and dairy produce are also good sources of the nutrient.

Who Needs a Vitamin B12 Injection?

People who develop vitamin B12 deficiency may need an additional source of the nutrient. For some, taking supplements can help. But certain conditions and medications can interfere with the absorption of the vitamin. For these people, vitamin B12 injections at a private GP clinic might be the answer.

In the UK, the most common cause of vitamin B12 deficiency is pernicious anaemia. People suffering from this condition may be prescribed vitamin B12 injections.
