Micronutrients consist of vitamins and minerals and differ from macronutrients (carbohydrate, protein, and fat) in that the human body requires much smaller amounts. The use of macronutrients for all physiologic processes is facilitated by micronutrients . Therefore, vitamins and minerals are necessary for many metabolic processes in the body, as well as to support growth and development.
