What are vitamins and minerals primarily responsible for in the body?

Vitamins and minerals play a crucial role in regulating body processes, which is why this answer is the most accurate. They serve as essential nutrients that aid various physiological functions, including enzyme activity, hormone production, and the maintenance of overall health. For instance, vitamins such as B-complex and minerals like magnesium are vital for energy metabolism; however, they do not provide energy in the same way carbohydrates, proteins, and fats do.

In addition to the regulation of metabolic processes, vitamins and minerals support the immune system, contribute to bone health, and facilitate the absorption of other nutrients, among other roles. They act as co-factors for enzymatic reactions, meaning they often help enzymes function effectively, thus maintaining homeostasis within the body.

Other options do not accurately capture the primary role of vitamins and minerals. Although they can influence specific aspects of energy metabolism and assist in muscle maintenance, their overarching function is more about regulation rather than the immediate provision of energy or the creation of muscle mass.
