What are micronutrients, and why are they essential?

Micronutrients are essential vitamins and minerals that the body requires in small amounts to function effectively. Unlike macronutrients, which include carbohydrates, proteins, and fats that provide energy and are required in larger quantities, micronutrients play crucial roles in a wide array of physiological processes, including immune function, bone health, energy production, and blood clotting.

Vitamins, such as A, C, D, E, and the B-complex vitamins, and minerals like iron, calcium, and potassium are classified as micronutrients. They do not provide energy directly but support the biochemical reactions that convert macronutrients into usable energy. The deficiency of these micronutrients can lead to various health issues, demonstrating their essential role in maintaining overall health and well-being.
