Vitamin B12 deficiency develops slowly, because the human body has the ability to store a large amount of it in the liver. In some cases, the stored vitamin B12 is enough to cover human needs even for several years. Unfortunately, what amount of vitamin is accumulated in the liver depends on individual characteristics. In practice, there may be a shortage even after a few months of transition to veganism. 

 

Vitamin B12 deficiency manifests itself in a non-characteristic way.
Occur 

fatigue (as a result of anemia), 

irritability, 

shortness of breath, 

loss of appetite. 

 

In extreme cases, there is a disturbance of consciousness, weakness of muscle strength, memory loss. These symptoms are associated with changes in the nervous system. 

The best way to check if a B12 deficiency has developed is to determine the total vitamin B12 in the blood serum. If you are on a vegan diet, do this test regularly, at least once a year! 

Supplementation with vitamin B12 on a vegan diet 

Vitamin B12 is found only in animal products (milk, eggs, meat). On a vegan diet it is necessary to supplement it from the very beginning. Many studies indicate that also on a vegetarian diet, where there are eggs and dairy products in the menu, there is insufficient intake of this vitamin. 

Small amounts of vitamin B12 are produced by the bacterial flora of the large intestine, but these are inadequate amounts. Adults are recommended for adults on a vegan diet, depending on the vitamin concentration in the blood 

from 25-250 mcg (microgram) per day, 

or 1000 mcg (microgram) 2 times a week. 

In case of strong deficiencies, injections with vitamin B12 are introduced. Before you start supplementing, choose the right dose after consulting your doctor or dietitian. 

 

Products enriched with vitamin B12 

Supplementation of supplementation may be included in the vegan menu of products to which vitamin B12 was added at the production stage. They are so-called enriched products. 

They are enriched most often 

vegetable drinks (formerly called vegetable milk) 

vegan dairy (mainly soy). 

Remember that these products should not be the only source of vitamin B12. To maintain its proper amount in the body, supplementation is needed, but in addition, plan 1-2 food meals enriched in your daily diet.
