What key role do vitamins serve in the body?

Vitamins serve a crucial role in facilitating biochemical functions within the body. They act as coenzymes or cofactors in various metabolic processes, which means they help enzymes to function properly and catalyze necessary biochemical reactions. These processes are essential for numerous bodily functions, including energy production, immune response, and the synthesis of hormones and neurotransmitters. Each vitamin has a specific role, contributing to the overall health and wellness of an individual by ensuring that metabolic reactions proceed efficiently. This relationship between vitamins and enzymes is fundamental to maintaining the body's homeostasis and overall metabolic balance.
