Vitamin B12 Test

In the body, there are two variants of vitamin B12: an active form, also called Active B12, and an inactive form. The active form, which is bound to the protein transcobalamin, is the one that the body's cells can use effectively, unlike the inactive form. Common standard tests measure total B12, which includes both the inactive and active forms of vitamin B12.

To get an accurate picture of your B12 status, especially if you are experiencing fatigue, thyroid problems, or other health issues, it is crucial to measure the active form of B12. Sometimes, a total B12 test may show normal levels, despite the active B12 form, which the body needs, being too low. This is because the active form constitutes only a small part of the total B12 value, typically between 10-30%.

For a more precise assessment of your B12 status and to ensure you are getting the necessary amount of the active form of vitamin B12, it is recommended to perform a test that measures the active form of B12 directly. With this test, you can get a more detailed and accurate assessment of your B12 health and take appropriate actions to improve your well-being if necessary.

B12 and its Special Absorption Capability

Vitamin B12 is water-soluble but requires a specific mechanism for absorption in the body, called Intrinsic Factor (IF). IF, produced by cells in the stomach wall, acts as a transporter for B12 in the blood. This complete package is absorbed through the intestinal wall and transported to the liver for storage or distribution to the body's tissues. The liver acts as a B12 reservoir that can last up to 20 years, reducing the need for continuous supply.

Why is B12 important?

• B12 is needed for nerve function, the formation of red blood cells, and DNA synthesis.
• Important for preventing anemia and neurological problems.

B12 Deficiency in Vegans and Other Risk Groups

Vegans, alcoholics, and individuals with stomach surgery are at high risk of B12 deficiency due to reduced production of Intrinsic Factor. Vegans especially need supplements as B12 is only found in animal sources.

Symptoms of B12 Deficiency

• Fatigue and confusion.
• Neurological problems such as tingling and muscle weakness.
• Severe cases can lead to pernicious anemia and "burning feet syndrome".
