The importance of vitamin B12

Vitamin B12 is a very important vitamin for your overall health, but it has an essential role in your blood cells and nerves. It takes part in the creation of genetic material in our cells and optimal levels of this vitamin protect our organism from megaloblastic anemia. The symptoms of this condition are an overall feeling of weakness and tiredness.

The absorption of this vitamin in our organism happens in two phases. First the hydrochloric acid isolates the vitamin form the proteins we’ve ingested and then it binds to the intrinsic factor, a protein that is naturally produced in the stomach. Afterwards, our organism absorbs the vitamin B12. Patients suffering from pernicious anemia usually lack the intrinsic factor, which is key in the absorption of this vitamin and therefore their body can’t absorb vitamin B12.

How does vitamin B12 deficiency happen?

People over the age of 60 have the highest risk of developing a vitamin B12 deficiency. The low limit for vitamin B12 is pretty high, which is why the majority of people don’t even know that their body lacks this important nutrient.

Increase your B12 intake

Vitamin B12 can be absorbed thorough food although as we mentioned some people can’t absorb it properly. If you suspect your body lacks this vitamin you should get tested and determine if you’re right.

The following groups of people are most at risk of a vitamin B12 deficiency:

  • People over 50 tend to have vitamin B12 deficiency pretty often because they fail to absorb vitamin B12 from the food they eat. Why? Because they have low amounts of hydrochloric acids in their stomach. And we mentioned earlier that this acid is essential for the proper absorption of this vitamin
  • People suffering from pernicious anemia cannot absorb sufficient amounts of vitamin B12, because they don’t have the intrinsic factor in their system. The solution to their problem is to take vitamin B12 supplements either orally or in the form of injections.
  • Individuals who deal with digestive problems, like Crohn’s disease or Celiac disease, or patients who have experienced gastrointestinal surgery (weight loss surgeries) are unable to absorb vitamin B12 properly.
  • Vitamin B12 deficiency is pretty common among vegans and vegetarians, because the only sources of this vitamin are products from animal origin. It’s also quite common for babies of vegan or vegetarian moms to be deficient in vitamin B12.
