Question 1

What are the signs of a vitamin B12 deficiency?

Accepted Answer

A vitamin B12 deficiency can cause various signs, such as fatigue, numbness, memory and concentration difficulties, digestive discomfort, loss of appetite and mood changes. It is important to consult a health professional to assess the signs and determine whether there is a vitamin B12 deficiency.

Question 2

What is the origin of vitamin B12?

Accepted Answer

In 1925, an American researcher discovered that eating liver cured anaemia in dogs, but it was only in 1948 that English and American scientists isolated and named vitamin B12 from a red pigment found in the liver. Later that year, American researchers showed that injections of this substance could help pernicious anaemia, a form of anaemia resistant to iron supplements.

Question 3

What is vitamin B12?

Accepted Answer

Vitamin B12, also known as cobalamin, is a water-soluble vitamin essential for the normal functioning of the human body in children and adults alike. It plays a crucial role in the formation of red blood cells, the proper functioning of the nervous system, DNA synthesis and the regulation of cellular metabolism. Vitamin B12 is mainly found in food, particularly in animal products such as offal, fish, shellfish, eggs, meat and dairy products.

Question 4

Which foods are good dietary sources of vitamin B12?

Accepted Answer

Meats: beef, lamb, veal, pork, poultry (chicken, turkey), liver (especially veal liver). Fish: salmon, trout, mackerel, tuna, sardine, herring. Seafood: mussels, oysters, clams, shrimp, crab. Dairy products: milk, yoghurt, cheese (especially blue cheese). Eggs: egg yolks. Nutritional yeast. Fortified foods: some breakfast cereals, soy-based meat substitutes, fortified plant milks. Vitamin B12 is barely present in plant-based foods (except fortified foods).

Question 5

Where can vitamin B12 be found in food?

Accepted Answer

Humans can synthesise their own vitamin B12 but in insufficient quantities to meet their needs. They can therefore find this vitamin in their diet, mainly in animal products, which are good sources of the vitamin. This is why vegetarians and vegans have more cases of vitamin B12 deficiency.

Question 6

What are the signs of excess vitamin B12?

Accepted Answer

It is extremely rare to consume an excessive amount of vitamin B12 in the long term. To date, the only notable side effect is a possible breakout of acne. No real toxicity has been demonstrated so far.

Question 7

Why is methylcobalamin more effective than cyanocobalamin?

Accepted Answer

Methylcobalamin is considered better than cyanocobalamin because it is already the active form of vitamin B12, which means the body can use it directly without conversion. Conversely, cyanocobalamin is a synthetic form that must be converted into active forms, a process that depends on the liver, enzymes and health status, and that can be less effective in some people. Methylcobalamin therefore acts more quickly and effectively, while cyanocobalamin is mainly used for its low cost.
