Micronutrients
Micronutrients are vitamins and minerals required in small amounts for normal body functions. They do not supply calories, but they participate in processes such as energy metabolism, oxygen transport, bone maintenance, immune function, nerve signaling, and the regulation of cell activity.
Vitamins are organic compounds, whereas minerals are inorganic elements. Minerals needed in especially small quantities are often called trace elements; the boundary between major and trace minerals is a classification convention, not a measure of importance. A tiny required amount does not make a nutrient optional.
Requirements are nutrient-specific and can vary with age, sex, pregnancy, lactation, and other circumstances. Authorities therefore publish separate reference values rather than one "micronutrient target." The EFSA dietary reference value framework covers individual vitamins and minerals for defined population groups. These values guide adequate population intake; they are not performance doses or a diagnosis of one person's status.
Deficiency can impair health and sometimes exercise capacity, but intake above adequacy does not automatically improve performance. Some nutrients can also be harmful in excessive amounts, particularly when concentrated supplements are stacked. A blood result, symptom, or restrictive diet should be interpreted in context by a qualified professional rather than used to justify broad megadosing.
A varied diet built from nutrient-dense foods usually supplies many micronutrients at once. Risk of low intake may rise when total food intake is chronically restricted, food groups are excluded without replacement, absorption is impaired, or needs and losses are unusually high. Athletes are not one homogeneous group, so heavy training alone does not create the same supplement requirement for everyone.
Supplements can be useful when a specific need, gap, or medically established deficiency is being addressed, but they do not reproduce the full nutritional profile of food. A meal plan should therefore be evaluated for variety and micronutrient coverage as well as calories and macronutrients.
