Which of the following is primarily considered a micronutrient?

Vitamins are classified as micronutrients because they are essential compounds that the body requires in smaller amounts to support various biochemical processes. Unlike macronutrients such as carbohydrates, proteins, and fats, which provide energy and are needed in larger quantities, vitamins play crucial roles in metabolism, immunity, and overall health without providing energy themselves.

Each vitamin plays specific roles in the body, such as aiding in the conversion of food into energy, supporting cell function, and functioning as antioxidants. Since these nutrients are only required in trace amounts, they are grouped under the category of micronutrients, highlighting their importance in maintaining health despite their small required quantities.
