Vitamin B12 is involved in the creation of every single cell in your body, so making sure you’re getting enough is really important to your overall health.
At Superdrug Online Doctor, we offer a vitamin B12 test kit which checks your vitamin B12 levels. When you get your results, our doctors can tell you if you have a healthy amount of vitamin B12 in your blood, and if you need any treatment.
Using a home test works in the following steps:
In some cases, the doctor may need to ask for more information. They may contact you by phone, so make sure your telephone number is up to date in your online account.
Due to a national increase in coronavirus testing, our test lab partners are experiencing delays of up to 3-4 days when delivering results from other test kits. We ask for your patience and compassion during these unprecedented times, and we're deeply grateful for your continued understanding.

Vitamin B12 (also called cobalamin) is really important, because it helps your body to make new cells every day. In fact, vitamin B12 is involved in the creation of every single cell in the human body, although it’s especially important in making sure your nervous system and blood cells are healthy and work properly.
The human body produces very little B12. You can’t actually absorb the vitamin B12 the body creates because it’s made in the colon, so it doesn’t pass through the small intestine (which is where most nutrients are absorbed). Because of this, you need to get your vitamin B12 from your diet or from supplements (commonly injections).
Foods high in vitamin B12 include:
Vitamin B12 isn’t found naturally in fruits, vegetables, or grains, so it can be difficult to get enough of it in your diet if you’re vegan. This is why B12 deficiency can be more common for people who are on a vegan diet.
The most common cause of B12 deficiency in the UK is an autoimmune condition called ‘pernicious anaemia’. This is when your immune system attacks a protein in your stomach called ‘intrinsic factor’, which is a protein that allows your body to absorb vitamin B12.
Vitamin B12 deficiency can lead to anaemia, which is when your red blood cells aren’t able to carry oxygen around the body properly. This can cause symptoms like tiredness, weakness, strange feelings on the skin, feeling out of breath, and a sore tongue.
At Superdrug Online Doctor, we offer a vitamin B12 blood test kit for you to test your vitamin B12 levels. To order your test kit, simply fill in a short questionnaire and place your order. Your kit will be sent to you by post.
Once you have received your kit, follow these steps:
If your B12 level is low, you’ll need to see your GP to get a couple more blood tests done. One of these is a ‘full blood count’ or ‘FBC’ to check your haemoglobin levels, and one is to check for pernicious anaemia by looking to see if you have antibodies against intrinsic factor. We’ll tell you what to do when we receive your results.
