What is the primary function of vitamins in the body?

The primary function of vitamins in the body is to ensure normal cellular functions and metabolism. Vitamins are essential micronutrients that play crucial roles in various biochemical processes. They act as coenzymes or precursors for enzymes that facilitate metabolic reactions, enabling the body to convert food into energy, synthesize hormones and proteins, and carry out other vital functions.

While vitamins do support the immune system and can influence energy levels indirectly, their overarching role encompasses a broader spectrum of functions related to maintaining homeostasis and promoting overall health. For instance, certain vitamins are crucial for DNA synthesis, red blood cell formation, and maintaining skin and nerve integrity.

The aspect of aiding in digestion is more closely related to other components of nutrition such as dietary fiber or specific minerals rather than the primary function of vitamins themselves.
