Biochemistry and biomarkers of Vitamin B12

Your body needs Vitamin B12 to work right. It helps make DNA and keeps your nerves and blood cells healthy. When you eat foods with B12 in them, it joins up with a protein called haptocorin.

This combo travels to your stomach, where acid frees the B12 so it can move on.

Doctors check for B12 levels to see if you have enough. Low levels might mean you don’t get enough B12 from food or your body can’t take it in well. To keep track of this, they look at markers in your blood called biomarkers that show how much is there.

If these numbers are too low, they will help determine what’s wrong and how to fix it.

Causes of acquired Vitamin B12 deficiency

Some people don’t get enough vitamin B12. This can happen if their body does not make a special protein called intrinsic factor. Without this protein, the body can’t grab and use vitamin B12 from food.

The name for this problem is pernicious anemia. Other folks might have trouble when their stomach or small intestine parts are not working right. This could be because of surgery or diseases like celiac or Crohn’s disease.

Certain medicines can also cause low vitamin B12 levels, especially in older adults. Metformin, used for diabetes and some heartburn drugs, lowers how much B12 your body can take in from food.

Eating animal foods is important because they contain lots of vitamin B12. If someone decides to eat only plant-based foods and doesn’t pick fortified foods or take supplements, they might need more vitamin B12.

Let’s discuss the best places to find vitamin B12 in our meals!
