Flavin enzymes of vitamin B2 are necessary for the formation of erythrocytes, antibodies, for the regulation of growth and reproductive functions of the body. Vitamin B12 also participates in the synthesis of nucleic acids, in the process of formation of blood erythrocytes, epithelial cells and enveloping nerve fibers of myelin.

Vitamin B5 is absorbed into the blood and then into the tissue where biosynthesis of coenzyme forms of pantothenic acid takes place, including coenzyme-A, which participates in lipid metabolism and the formation of antibodies and hormones.
