Methylcobalamin B12 is active immediately upon absorption,
while other forms(e.g., Cyanocobalamin) must be converted to methylcobalamin in a two-step process.
That is, after the initial treatment with injections of vitamin B12,
dietary supplements of vitamin B12(Cyanocobalamin tablets) may be advised instead of injections.
Cyanocobalamin(vitamin B 12)-
is involved in the exchange of proteins and nucleotides, catalyzes the process of myelin synthesis(the sheath of nerve fibers that is necessary for the normal spread of nerve impulses), hemoglobin(with anemia deficiency anemia develops).
