What happens with a deficiency of cobalamin?

Deficiency of vitamin B12 may be a consequence of a violation of the body's ability to absorb B12 from the digestive tract. Since cobalamin is found only in animal products, vegans and vegetarians are at a higher risk of developing vitamin B12 deficiency. It is unlikely that taking B12 will lead to an increase in athletic performance in athletes who receive it in sufficient quantities with food. Like vitamin B6, vitamin B12 can reduce homocysteine ​​levels, thereby reducing the risk of atherosclerosis and cardiovascular diseases.

The complex of B vitamins contains eight vitamins. All of them play different roles in a variety of biological functions, including energy metabolism, reproductive health, and the formation of red blood cells. Studies have shown that taking B vitamins is unlikely to have any effect on sports performance and physical performance, especially in the absence of a deficit. A balanced and varied diet with an abundance of full-blown sources of protein, nuts, green vegetables and legumes usually contains sufficient amounts of B vitamins.

Deficiency of vitamins of group B can be a consequence of poor assimilation of nutrients, absence of certain foods in the menu or a reduced total caloric content of the diet. Groups at increased risk of developing deficiency of certain B-complex vitamins include elderly people, vegetarians and vegans, as well as people who sharply reduce body weight due to excessive loads or reduced calories. B vitamins play an important role in the body's ability to generate energy, so it is important to get them in large quantities from food or from nutritional supplements.
