Vitamin B12 (Cobalamin)
Vitamin B12 performs a variety of important functions in the body: it can help to reduce tiredness and fatigue and to maintain normal energy metabolism, it contributes to the normal functioning of the psyche as well as the immune and nervous systems, it plays a role in the formation of red blood cells (also known as erythropoiesis) and it supports normal homocysteine metabolism, as well as being required in the process of cell division. Vitamin B12 also acts as a coenzyme in the body. This means that certain enzymes in our body require B12 in order to fulfil their tasks. In other words, many enzymatic reactions are directly dependent on vitamin B12 and cannot take place without it.
Vitamin B12 MH3A® Formula
Vitamin B12 (cobalamin) occurs in a variety of different chemical structures, all of which perform different tasks in the body. The natural forms of vitamin B12, which can exert a direct effect on the body, are considered bioactive coenzymes. Synthetic forms of vitamin B12, such as cyanocobalamin, must first be converted into a natural form by the body in order to be effective.
Methylcobalamin and adenosylcobalamin are the bioactive coenzyme forms of vitamin B12. Because they each have different areas of action and take part in completely different reactions, the body is able to convert these forms from one to the other. Methylcobalamin plays a role in the methylation cycle within the cell plasma, a far-reaching function influencing various body processes from blood cell synthesis to the functioning of the nervous system. Adenosylcobalamin, on the other hand, takes effect in the mitochondria, the powerhouse of the cell. There it plays a role in the citrate cycle, the central metabolic cycle for energy production. The third natural form of vitamin B12 is hydroxocobalamin, a form which can be found in many foods. It makes up a significant amount of the total B12 in the blood and binds particularly well to vitamin B12 transport molecules. It is thus not excreted as quickly; hydroxocobalamin is the form of B12 with the highest capacity for building long-term stores in the body and can be easily converted into either of the two active coenzyme forms as needed.
