What role do vitamins play in the body?

Vitamins are essential for biochemical functions and maintaining health, which underscores their importance in numerous physiological processes within the body. These organic compounds play critical roles as coenzymes or precursors for enzyme systems, facilitating various biochemical reactions necessary for metabolism, immune function, and overall health.

For instance, vitamins such as B-complex vitamins are crucial for energy metabolism, while vitamin D is important for calcium homeostasis and bone health. Additionally, vitamins A, C, and E serve multiple functions, including supporting vision, skin health, and immune response.

Furthermore, while some vitamins have antioxidant properties, their roles extend well beyond that single function, indicating their multifaceted contributions to health and wellness. Their absence can lead to deficiencies that can significantly impair bodily functions, demonstrating their necessity for maintaining optimal health.
