Why are vitamins important for the body?

Vitamins play a crucial role in metabolic processes and immune function, making them essential for maintaining overall health. They serve as coenzymes or cofactors in numerous biochemical reactions that are vital for producing energy, synthesizing DNA, and supporting the metabolism of carbohydrates, fats, and proteins. Each vitamin has specific functions; for example, B vitamins are integral to energy production, while vitamins A, C, D, and E contribute significantly to immune system health by supporting various cellular functions.

These micronutrients help the body respond effectively to pathogens, thus enhancing the immune response. Without adequate vitamins, the body becomes less efficient at performing these essential tasks, which can lead to deficiencies and associated health issues. This makes understanding the role of vitamins in metabolic processes and immune function a fundamental aspect of nutrition and health.
