What is the primary purpose of vitamins in the body?

Vitamins play a crucial role in supporting metabolic processes within the body. They act as coenzymes or precursors for various biochemical reactions essential for the metabolism of carbohydrates, fats, and proteins. Each vitamin has specific functions that contribute to the metabolic pathways, such as energy production, the synthesis of hormones and red blood cells, and the maintenance of the nervous system.

For instance, B vitamins are vital for energy metabolism, while vitamins C and E function as antioxidants, helping to protect the body from oxidative stress. Additionally, some vitamins are critical for enzymatic reactions necessary for the repair and maintenance of cells, contributing further to overall metabolic health.

In contrast, while energy sources are primarily derived from carbohydrates, fats, and proteins, they do not include vitamins. Muscle building is largely influenced by protein intake and exercise rather than vitamins alone. Similarly, while certain vitamins can play roles in structural support (like vitamin D aiding in calcium absorption for bone health), their primary function lies in facilitating the various metabolic processes that sustain life and health.
