Vitamin B12 (cobalamin) plays an important role in DNA synthesis and the function of the central nervous system. It is essential for the normal function of all body cells, especially those of the bone marrow, gastrointestinal tract and nervous system, and is also necessary for the formation of red blood cells. Supplementation with Vitamin B12 is particularly important for the elderly, who are susceptible to deficiencies due to reduced secretion of the 'intrinsic factor' (necessary for B12 absorption).
