Vitamin B12 is a vital component in many cellular functions, including DNA synthesis. Deficiency can result in cognitive/mental problems, dizziness, and numbness and - if left untreated - permanent neurological damage.
In our clinical experience, vitamin B12 deficiency is quite common. Estimates suggest that up to 20% of the elderly population may be deficient or deplete in Vitamin B12. Pregnant women and young children, vegetarians, vegans, and patients with intestinal problems or those taking stomach acid suppressants are all at increased risk of B12 deficiency.
A vitamin B12 blood test is included in the process of testing for vitamin B12 deficiency, as this blood test alone is not enough to rule out B12 deficiency. For a more comprehensive test, add on an MMA test, which can help diagnose an early or mild vitamin B12 deficiency.
High levels of folic acid supplements can mask B12 deficiency. Please tell us if you are taking folic acid supplements.
The day of the test
Remember to take I.D. with you when going to take a test.
Arrive in good time and sit down quietly for 15 minutes before taking the test.
What happens next?
The lab sends the results to your personal dashboard, with comments from both a doctor and a nutritionist. If results are abnormal, we recommend seeing a doctor and, if appropriate, booking an appointment with a Nordic Wellth nutrition lifestyle specialist.
You may need to make lifestyle and dietary changes.
Why test vitamin B12 (cobalamin)?
Symptoms related to B12 deficiency include mood swings, hand/feet numbness, ‘brain fog’, fatigue, headaches, depression, anemia, infertility, insomnia, irritability, and anxiety.
Vegans, vegetarians, and others who eat no or little meat/seafood, or have celiac/intestinal disease, may all have an increased risk of vitamin B12 deficiency.
You have a history of low B12, or other reasons that suggest you may have low B12.
You take a drug, such as hydrocortisone or antacids, which increases the need for B12.
