What role do vitamins play in the body?

Vitamins are crucial organic compounds that support a wide range of physiological functions in the body. Their primary role is to assist in various biochemical processes necessary for maintaining health, which includes supporting normal growth and activity. Different vitamins have specific functions, including aiding in metabolism, promoting immune function, and facilitating the synthesis of important molecules such as hormones and enzymes.

For example, certain B vitamins are involved in energy production, while Vitamin D plays a vital role in bone health through its effect on calcium metabolism. Unlike macronutrients such as carbohydrates, fats, and proteins, vitamins do not serve directly as a primary energy source, highlighting the importance of their supportive yet distinct role in the body’s overall functioning. Additionally, while some vitamins do exhibit antioxidant properties, they are not limited to that function and contribute to a broad array of bodily processes, thus confirming that their essential nature extends far beyond just detoxification or acting as antioxidants.
