Explanation:

Vitamins are organic compounds that are essential for normal growth and nutrition. They are required in small quantities for the body's metabolism, growth, and development. While some vitamins like vitamin A can contribute to vision health, their primary role is to regulate various body processes such as cell function, immune system support, and energy production (not directly providing energy like macronutrients - carbohydrates, fats, proteins). Building muscle is mainly associated with protein intake.
