What is considered a micronutrient?

Micronutrients are essential nutrients required by organisms in small quantities for proper growth and development. Vitamins are a prime example of micronutrients because they facilitate various biochemical functions within the body, including metabolism, immunity, and overall cellular function. Unlike macronutrients, which are needed in larger amounts (such as carbohydrates, proteins, and fats), vitamins are necessary in minute quantities but are vital for well-being.

In contrast, carbohydrates, water, and proteins are categorized as macronutrients. Carbohydrates provide energy, proteins are critical for building and repairing tissues, and water is essential for hydration and biochemical processes. Thus, vitamins stand out as the only examples of micronutrients among the choices provided.
