The micronutrients(Vitamins/Minerals) play an important role by ensuring proper functioning of cells and tissues.
Each vitamin and trace mineral play a specific role in the body. For example, Vitamin C acts as antioxidant protecting cells from environmental damage, healing wounds and maintaining connective tissue whereas minerals like sodium, potassium and chloride function as electrolytes that assist in communication between cells necessary for nerve impulses and muscle contraction.
Some products mimic the nature by adding artificial vitamins or minerals which have an identical form and function to those found in nature, but they are manufactured synthetically to meet extremely high standards of processed products.
