Vitamin B2 (riboflavin) is a precursor to coenzymes involved in the growth and repair of skin and tissues lining the gastrointestinal tract, as well as the synthesis of amino acids. B2 is necessary for the formation of pigments essential to vision
Riboflavin, also known as vitaminB2 is an easily absorbed micronutrient with a key role in maintaining health in humans and animals. It is the central component of the cofactors FAD and FMN, and is therefore required by all flavoproteins. As such, vitamin B2 is required for a wide variety of cellular processes. It plays a key role in energy metabolism, and for the metabolism of fats, ketone bodies, carbohydrates, and proteins. It is also used as an orange-red food colour additive, designated in Europe as the E numberE101.
