Vitamin test that analyzes your vitamin B12 levels (cobalamin. Your overall energy, concentration, focus and memory are affected by your vitamin B12 levels. Vitamin B12, also known as cobalamin, is needed for cell metabolism and the formation of red blood cells. Vitamin B is also necessary for the functioning of the nervous system.
Do you suspect a vitamin B12 deficiency?
If you are at risk for a B12 deficiency or if you are experiencing symptoms that may be due to a vitamin B12 deficiency, such as headaches, fatigue, difficulty concentrating or dizziness, it may be a good idea to test your B12 levels. A lack of vitamin B12 can lead to a type of anemia called megaloblastic anemia, which results in fatigue, weakness and paleness. Since B12 also affects your nervous system, a deficiency can cause numbness and tingling in the extremities, balance problems, memory problems, depression, confusion and other neurological symptoms. In addition above, B12 deficiency can cause fatigue.
How can I increase my intake of vitamin B12
Vitamin B12 is found primarily in animal products such as meat, fish, shellfish, dairy products and eggs. This means that people who follow a strict vegetarian or vegan diet are at higher risk of B12 deficiency. It is therefore of extra importance to monitor B12 levels and possibly take supplements if the analysis shows low values.
What level of vitamin B12 is considered abnormal?
To maintain an adequate level of vitamin B12, the concentration should be above 250 pmol/L. Values below this limit may mean an increased risk of symptoms and potential neurological problems as well as anemia, especially if the B12 deficiency persists over time. In the case of low levels, it may be necessary to adjust the diet or take supplements to ensure adequate intake.
B12 is very important for your health
Measuring your B12 level is one of the most effective ways to understand why you feel tired, lack energy or unfocused – even when other tests look normal. A deficiency of vitamin B12 can develop gradually over several years and is often overlooked in the early stages. Through a simple blood test, you get quick insight into your nutritional status and the opportunity to act before the deficiency affects your well-being. A B12 analysis is also valuable for those of you who are already taking supplements or receiving B12 injections and want to monitor the effect of the treatment. The test can also be combined with other nutritional analyses, such as folate (B9) and iron status, for a more complete picture of your energy metabolism and blood formation. By knowing your values, you can optimize your energy, improve your mental acuity and strengthen your long-term health.
Who is at increased risk of vitamin B12 deficiency?
The risk of vitamin B12 deficiency is higher in people who eat a vegan or very limited vegetarian diet, since the vitamin is mainly found naturally in animal foods. Older people may also have more difficulty absorbing B12 from food.
Deficiency can also occur when absorption in the stomach or intestines is impaired, for example in pernicious anemia, inflammatory bowel disease, celiac disease or after certain surgeries on the stomach or intestines. Long-term use of certain medications, including metformin and antacids, can also affect B12 levels.
Are additional blood tests needed?
A B12 value always needs to be assessed together with symptoms and other test results. In the case of a low or borderline value, the analysis may need to be supplemented with, for example, methylmalonate and homocysteine to assess whether there is a functional B12 deficiency.
Methylmalonate rises more specifically in the case of a vitamin B12 deficiency, while homocysteine may be elevated in both B12 and folate deficiency. It may also be relevant to analyze the blood status, MCV, folate and iron status, since several deficiencies can occur simultaneously and cause similar symptoms.
B12 deficiency can exist without anemia
Vitamin B12 deficiency can affect the nervous system even before clear anemia has developed. Neurological symptoms such as numbness, tingling, balance problems or memory impairment should therefore be taken seriously even if the hemoglobin value is normal.
In the case of clear symptoms, low values or suspicion of impaired absorption, further medical investigation may be needed to identify the cause and determine which treatment is appropriate.
