(Cyanocobalamin) and
Folic Acid
Because of the continuing need to replenish red blood
cells, the erythropoietic cells of the bone marrow are
among the most rapidly growing and reproducing cells
in the entire body. Therefore, as would be expected,
their maturation and rate of production are affected
greatly by a person’s nutritional status.
Especially important for final maturation of the red
