What is the primary function of Vitamin B2?

The primary function of Vitamin B2, also known as riboflavin, is as a coenzyme that plays a crucial role in the conversion of nutrients into energy. Riboflavin is integral in various metabolic processes, particularly in the metabolism of carbohydrates, fats, and proteins. It is a key component of the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which are vital for cellular respiration and energy production within the mitochondria.

Through its role as a coenzyme, Vitamin B2 facilitates important biochemical reactions that convert the energy from food into a form that the body can use, essentially aiding in the efficient production of ATP (adenosine triphosphate), the energy currency of the cell. This makes riboflavin essential for maintaining energy levels and overall metabolic health.
