When your body has all the nutrients and vitamins it needs, it can keep you feeling happy and healthy. However, when it is lacking in something then it may not be long before you start feeling unwell. Vitamin B12 is one of the essential vitamins the body needs to thrive so when it doesn't absorb enough it can lead to a range of symptoms. Today, we're looking at what our body needs vitamin B12 for and what to do if you think you have a deficiency.

What is Vitamin B12?

Vitamin B12 is a nutrient that helps keep our nerves and blood cells healthy. Not only that, but it also helps produce our DNA - the genetic material that is in all cells that make us who we are! However, if we don’t have enough B12 in our body then it can lead to a variety of health concerns, including a type of anaemia which can make you feel very unwell.

 

Our bodies do not naturally make B12, instead, it is found in food sources such as beef, eggs and milk, and also in supplements. People who do not eat foods containing B12 may find they have symptoms of deficiency. However, this isn't the only reason you may have low levels. Other causes include your stomach not being able to absorb B12 from the foods you are eating or if you have a digestive disorder such as Crohn's or celiac disease.

How to Test for a B12 Deficiency

If you are showing symptoms of a B12 deficiency you can either visit your GP or you can order an at-home test from Superdrug's Online Doctor. We have two kinds of kits available, a basic one which will check your B12 levels and an extended kit which will test your B12, folate and intrinsic-factor antibodies.

Vitamin B12 Injection Service

If you have taken a test and it shows you are B12 deficient, then an effective way to treat it is with a vitamin B12 injection.

This injection is available via our Superdrug Health Clinics; however, in order for you to receive the injection, you must be able to prove you have a deficiency either with the results from your GP or by taking the B12 extended test via Superdrug Online Doctor.

The injection is given every 2-6 months, depending on how low your levels are, and each dose cost £29.
