Understand the definition of vitamins: Vitamins are organic compounds, meaning they contain carbon, and are required in small amounts for normal metabolic processes in the body.
Clarify the misconception about energy: Vitamins do not provide a direct source of energy for cells. Energy is primarily derived from macronutrients like carbohydrates, fats, and proteins.
