Folic acid enhances chemical reactions that contribute to the production of red blood cells, the manufacture of DNA needed for cell replication and the metabolism of amino acids (compounds necessary for the manufacture of proteins).
Zinc is essential to numerous physiological processes, including the function of many enzymes in the body. Deficiency may lead to poor night vision, slow healing of wounds, poor sexual development and function in males, poor appetite (perhaps owing to a decrease in the sense of taste and smell), a reduced ability to ward off infections, diarrhea, dermatitis and in children, retarded growth.
