Vitamin B12 is an essential nutrient that is crucial for brain function, nerve health, the formation of healthy red blood cells, and the creation of DNA. As vitamin B12 only naturally occurs in meat, fish, and dairy products, people who do not eat enough of these foods or have problems absorbing this vitamin may develop a deficiency. Detecting and treating a vitamin B12 deficiency before severe symptoms or nerve damage occurs is very important. Use this self-test to check your vitamin B12 levels quickly and easily from home.

Summary of Biomarkers
Approximately ten percent of people living in Western countries suffer from a vitamin B12 deficiency. This is expected to be increasingly associated with the growing number of people who follow a vegetarian or vegan diet, as vitamin B12 is primarily found in animal products, such as milk, meat, fish and eggs. Because your body stores vitamin B12, you often only notice after a few months that you have a possible deficiency. If you are deficient in vitamin B12, you can develop a form of anemia with symptoms such as fatigue, shortness of breath, chest pain and a lack of appetite. Elderly people with a vitamin B12 deficiency may also have problems with their memory. If you want to test specifically for anemia, you can do so with Homed-IQ’s anemia test. Adults need 2.8 micrograms of vitamin B12 per day. Homed-IQ’s Vitamin B12 Test measures the amount of vitamin B12 in your blood, which can indicate a potential deficiency.
Causes of Vitamin B12 Deficiency
What are the most common causes of vitamin B12 deficiency?
- Lack of B12 in diet: Vitamin B12 cannot be produced by our bodies, meaning it needs to be obtained through food or drinks. Your body stores vitamin B12 for future use, and it can take years before your body uses up its B12 reserves. Vitamin B12 is almost exclusively found in animal products, so people who follow a vegan or vegetarian diet should include foods fortified with vitamin B12 in their diet.
- Pernicious anemia: This rare autoimmune condition is one of the most common causes of a B12 deficiency. During this disease, the immune system attacks the cells in the stomach that produce intrinsic factor, a protein needed for your body to absorb B12. As your body needs vitamin B12 to make red blood cells, anemia occurs.
- Conditions affecting the stomach or intestines: Crohn’s disease, gastritis, Celiac disease and other stomach or intestinal diseases can affect B12 absorption.
- Certain medications: some medicines can reduce the amount of vitamin B12 in your body or make existing deficiencies worse. Your doctor should inform you of medications that could affect your vitamin B12 levels.
What do the results of this test mean?
Vitamin B12 Deficiency
A vitamin B12 level below 145 pmol/L indicates a vitamin B12 deficiency. This can be caused by different factors. If your vitamin B12 is low, see your GP. While some people can take supplements or make changes to their diet to replenish their B12 levels, others may require vitamin B12 injections or have an underlying condition that is causing low B12.
To boost your vitamin B12 through diet, eat more foods that contain it. These foods include:
- Fish and shellfish
- Beef, chicken, and liver
- Fortified breakfast cereals
- Low-fat milk, yogurt, and cheese
Sufficient Vitamin B12
A vitamin B12 level above 145 pmol/L and below 569 pmol/L is sufficient.
Elevated Vitamin B12
A vitamin B12 level above 569 pmol/L is elevated. Elevated vitamin B12 is uncommon as excess B12 is usually removed from the body in urine. Elevated vitamin B12 could be due to:
- Liver disease (cirrhosis or hepatitis)
- Kidney failure
- Myeloproliferative disorders
- Overconsumption of supplements
If your Vitamin B12 is elevated, see your doctor for further advice. High vitamin B12 can be indicative of other illnesses that require immediate attention.
