Vitamin B12 in bodybuilding

Biologically active cobalt-containing substances or cobalamin are B vitamins. These organic compounds are represented by:

  • 5-deoxyadenosyl cobalamin;
  • cyanocobalamin;
  • hydroxycobalamin;
  • methylcobalamin.

These substances are known more under the general name Vitamin B12. Most of the cobalt-containing compounds entering the human body are cyanocobalamin. Its main role is to stimulate blood formation processes, which is also called Castle's external factor.

These organic compounds are produced by bacteria and archaea in a natural environment. The human body contains these biological substances in two varieties of enzymes. One belongs to the L-methylmalonyl-CoA group, and the second is methyltransferase.

Biological functions and pharmacokinetics

Substances of group B12 are actively involved in two enzymatic reactions. The first is to stabilize and accelerate the transfer with subsequent replacement of atoms. The second also represents a transfer, but between molecules that are part of a methyl group. Organic cobalt-containing substances have a complex and cyclic cleavage structure, therefore, are not completely excreted from the body.

Cobalamin breaks down in the liver, becoming part of the bile that enters the intestines, and then partially enters the bloodstream, where it continues to be absorbed. As it was established during the studies, the initial excretion, which is not always complete, takes at least 500 days, which is 1.5 years. Vitamin B12, which is administered intramuscularly or subcutaneously, that is, by injection, when its maximum concentration is reached a maximum after an hour, is best absorbed.

In liquid form, the substance has a pinkish characteristic color. Its distinguishing feature is its good contact with plasma proteins. This allows you to create a strong connection. The combination of these compounds with each other is at least 90%, which is a fairly high figure.

For bodybuilders, the value of cobalamin cannot be overestimated. Organic matter plays a crucial role for protein metabolism. Deficiency of the compound leads to its violation, and this is fraught with the most unfavorable processes.

The role of vitamin B12

Cobalamin in bodybuilding is a powerful organic compound that has a wide range of beneficial effects. If applied correctly, one can achieve high results in the sports field.

Bodybuilders take vitamin B12 to:

  • improving the quality and stable course of protein synthesis;
  • the formation of red blood cells, since the substance is involved in hematopoiesis;
  • the synthesis of creatine, as well as myelin, which is required for the formation of an electrically insulating sheath of nerve fibers.

Cobalamin is part of the enzymes that a person needs to maintain vital functions.

The use of vitamin B12 in bodybuilding

The use of vitamin B12 to achieve sports goals has become widespread. This is due to the fact that the substance is required by the human body to better restore and maintain high performance.

Bodybuilders take cobalamin, because its effect on the bodybuilder's body is in the following physiological functions:

  • participation in carbohydrate metabolism;
  • increased strength with which muscle impulses are reduced, as well as improved coordination of movements;
  • stabilization, balance, normalization of central nervous system function;
  • active stimulation of muscle groups due to active trophic nerve fibers.

In addition, cobalt-containing biologically active substances have a powerful anabolic effect on the bone marrow.

Sources of Vitamin B12

Cobalamin is not produced by plant or animal organisms. This also applies to people. Vitamin B12 is the only representative of its group that can exclusively synthesize microorganisms, and, therefore, it is possible to replenish its norm by taking injections or with food. It all depends on the degree of need.

Among the food products, the organic compound in question is present in lamb, pork liver, beef, chicken eggs, shrimp, mussels, milk, mackerel, cottage cheese. These are not the only sources of B12, but in other foods it is present in smaller quantities. The substance is part of a breakfast cereal, some food additives, as well as bars, both chocolate and cottage cheese, but in a minimum percentage ratio.

Dosages and rules of administration

The use of vitamin B12 in bodybuilding differs from the intake of a substance according to medical indications. If the bodybuilder is actively training, he needs to take 10-24 micrograms of the substance per day. There should only be one daily intake. The daily rate is not recommended to be split. An overdose is not dangerous, because cobalamin is not a toxic compound.
