Vitamin B 12 is not synthesized either by animals or plants, its content depends solely on the ability to preserve the vitamin produced by microorganisms (for example, bacteria in the soil). Such opportunities are more in animals, so good sources of vitamin B12 are almost limited to products of animal origin.
Beef liver is one of the byproducts actively used in cooking, in the diet of athletes and in dietary nutrition. There are many ways to prepare the liver as an independent dish, and additions to garnishes. It is used in most of the world’s cuisine in cooked, baked, stewed and fried.

5 Benefits of Vitamin B12 for Human Health
1. Prevents cancer
Deficiency of vitamin B12 does not give salts of folic acid to be transformed into an active form. Because of this, faults are formed in the DNA circuits due to improperly formed links. Damaged DNA chains, according to scientists, can cause cancer. It is believed that supplements with vitamin B12 and folic acid can prevent the appearance of cancer cells and even treat certain types of this disease. Vitamin B12 is unusual in its “origin”. Unlike most others synthesized by plants or animals, the only source of vitamin B12 are the tiny microorganisms – bacteria, yeast, mold, algae. The most famous function of vitamin B12, is an indispensable role in the development of red blood cells. DNA molecules (DNA, or deoxyribonucleic acids, are a substance in the nucleus of the cell that contains genetic information) ripen in red blood cells. Without B12, DNA synthesis is impossible, and the information necessary for the formation of red blood cells is not transmitted. So there is a disease of malignant anemia.
2. Strengthens brain health
Insufficient vitamin B12 increases the risk of Alzheimer’s disease in the elderly. It helps maintain a low level of homocysteine, which plays an important role in the development of this disease. It is also important for care, reduces the symptoms of ADHD and improves memory.
3. Prevents depression
Numerous studies have confirmed the relationship between depression and vitamin B12 deficiency. It is responsible for the synthesis of neurotransmitters, which affects the mood of a person. In one study, published in the American Journal of Psychiatry, 700 women with disabilities older than 65 years were involved. The researchers found that women with vitamin B12 deficiency are twice as likely to suffer from depression than women in whose diet there is enough B12.
4. Prevents anemia and erythrocyte production
Vitamin B12 is essential for the development of healthy and normal red blood cells. B12 prevents anemia, especially megaloblastic anemia. It is a form of anemia, in which a smaller number of erythrocytes is produced, while they are large and immature. They are not able to carry the necessary amount of oxygen to tissues and organs, which is usually manifested in symptoms of weakness and fatigue.
5. Increases energy reserves
Vitamin B12 turns carbohydrates, proteins and fats, obtained from food, into “fuel” for our body. That’s why people with its deficiency feel constant fatigue. Vitamin B12 by means of signals to neuromediators shortens our muscles and gives an energy boost for the whole day. To maintain the energy charge at the optimal level throughout the day, eat foods containing vitamin B12 in large quantities regularly.
