Vitamin C is found in all living tissues, and most animals are capable of synthesizing their own supply from glucose. However, humans cannot make their own vitamin C, and must obtain it from a dietary supplement or from food supplement. It is required for the synthesis of collagen, an important structural component of blood vessels, tendons, ligaments and bone. It is vital for the function of the immune system. Vitamin C supplementation has been shown to reduce the severity of symptoms associated with the common cold. In children who experience extreme physical stress, vitamin C may be helpful in preventing respiratory infections. Vitamin C has also been used to promote wound healing and treatment of megaloblastic anemia.
Zinc is an essential trace element for humans. It is a constituent of over 200 metallo-enzymes. It is found in many tissues including pancreas, liver, kidneys, lungs, muscles, bones, eyes and endocrine glands. Zinc is a mineral that helps support the proper growth and development of children. It has various roles in the human system, and participated in systemic and intracellular control and integration, and in mechanisms of the major metabolic pathways involving tissue and protein synthesis, gene expression and embryogenesis and apoptosis. Zinc is thus essential for growth, sexual maturation, sensory, cognitive and immune function.
