Micronutrients are essential vitamins and minerals required by the body in small amounts to maintain optimal health, growth, and development. Unlike macronutrients—such as carbohydrates, proteins, and fats—which provide energy and structural support, micronutrients play critical roles in metabolic processes, immune function, and cellular repair. They are not a source of energy but are vital for converting food into energy, synthesizing hormones, and supporting nerve function.

Vitamins, which are organic compounds, include fat-soluble vitamins (A, D, E, and K) and water-soluble vitamins (B-complex and C). Fat-soluble vitamins are stored in the body’s fatty tissues and liver, while water-soluble vitamins are excreted in urine and must be replenished regularly. Minerals, which are inorganic elements, include major minerals like calcium, phosphorus, and magnesium, as well as trace minerals like iron, zinc, and selenium. Each micronutrient has specific functions; for example, vitamin C aids collagen formation and immune defense, while iron is necessary for hemoglobin production and oxygen transport.

Deficiencies in micronutrients can lead to health issues such as anemia (from iron or vitamin B12 deficiency), weakened immunity, or impaired bone development (from vitamin D or calcium deficiency). Conversely, excessive intake of certain micronutrients, particularly fat-soluble vitamins, can cause toxicity. A balanced diet rich in fruits, vegetables, whole grains, lean proteins, and dairy products typically provides adequate micronutrients. In cases of deficiency, dietary supplements may be recommended under medical supervision.

Micronutrient needs vary by age, sex, and physiological state, such as pregnancy or lactation. Public health initiatives often focus on addressing micronutrient deficiencies through fortified foods, dietary diversification, and targeted supplementation programs, particularly in regions where dietary intake is insufficient. Regular monitoring of nutrient status through blood tests or dietary assessments helps identify and address deficiencies before they lead to serious health complications.
