Vitamin B12 is a water-soluble vitamin that is only partially accumulated in the body, so it must be regularly consumed through food.

Vitamin B12 performs various functions within the organism, it is necessary for the metabolism of amino acids, nucleic acids and fatty acids. It is also essential in the production of red blood cells and in the formation of the bone marrow.

Vitamin B12 always favors the transformation of nutrients into energy. Vitamin B12 is present in foods of animal origin such as meat, fish, milk and eggs.

It should be noted, however, that the quantity of vitamin B12 absorbed compared to that actually present in food is 60% for meat and milk, 30-40% for fish products and less than 10% for eggs.

Furthermore, cooking reduces the amount of vitamin B12 present in the food to 1/3. The daily requirement of vitamin B12 for adults corresponds to about 2-2.4 mg, while for pregnant or breastfeeding women the amount is greater.

Vitamin B12 deficiency is a form of anemia, resulting from poor production of blood cells, which can cause paleness, weakness, tingling in the limbs and fatigue. Diagnosis is made by blood tests.

Vitamin B12 deficiency is to be avoided in pregnant women, to avoid harmful consequences on the unborn child, but also in athletes, since its deficiency or reduced intake leads to greater fatigue, increased recovery times and reduced ability to produce power.
