A vitamin B12 deficiency? When should I pay extra attention?

Vitamin B12 deficiency is more common than is generally assumed. It is often wrongly thought that B12 deficiency only occurs in people with pernicious anemia (vitamin B12 deficiency due to autoimmune gastritis) and in strict vegetarians.

To get enough vitamins, it is important that you eat healthy and varied.

Prevent B12 deficiency

How is vitamin B12 absorbed in your body?

The absorption of vitamin B12 is a rather complicated process. Vitamin B12 is not simply absorbed through the intestinal wall. In order to be absorbed, vitamin B12 needs a substance to which it can bind. This substance is called 'intrinsic factor' and is produced in the stomach. Linked to the intrinsic factor, vitamin B12 is transported via the stomach, further through the intestinal tract. Once it has arrived in the last part of the small intestine, vitamin B12 is absorbed into your blood.

Impaired absorption of B12

There are also people who are less able to absorb vitamin B12. For example, you absorb too little vitamin B12 if there is too little intrinsic factor produced in your stomach. Or when the absorption in the intestines is prevented for some reason. This can be the case if you have ever had intestinal surgery. Older people have more difficulty absorbing vitamin B12 and therefore a deficiency. This is because the production of stomach acid can decrease as you get older.

How quickly does a vitamin B12 deficiency develop?

A vitamin B12 deficiency can occur if you:

  • The vitamin is not absorbed sufficiently;
  • Because you are not getting enough vitamin B12 in your diet.

A vitamin B12 deficiency is not common if you eat animal products. Are you vegetarian or vegan? Then it is a different story. You must then supplement your healthy diet with vitamin B12 to absorb enough of it. This can be done with supplements.

How do you find out if you have a vitamin B12 deficiency?

Are you experiencing symptoms of a vitamin B12 deficiency? For example, do you have pale skin or a feeling of fatigue? Do you feel a bit light-headed or do you have little appetite? Then contact your GP. The GP can have your blood tested to see if there is a vitamin B12 deficiency.

Vitamin B12 Supplements

Vitamin B12 supplements are a great way to supplement the vitamin B12 you get from your diet. Vitamin B12 can help keep your nervous system healthy, support the production of red blood cells and help with fatigue.

It is important to choose quality supplements that are well absorbed by the body. The Vitamin B12 melt tablets from Ovabalance, for example, contain a bioactive and well-absorbable form of vitamin B12. They are therefore a good addition to a vegetarian or vegan diet.

The Ovabalance VitaminB12 supplement contains B12 in the form of methylcobalamin. This is a bioactive form of vitamin B12. This means that the vitamin does not need to be converted again in the body before it is effective.

Vitamin B12 during pregnancy

That is why vitamin B12 is also included in the Ultimate Multi Mama, specially developed for women: a multivitamin for women who want to have children, pregnant women or women who are breastfeeding.
