Riboflavin, (also known as Vitamin B2), is a water-soluble essential micronutrient that is a vital to the metabolism of fats, carbohydrates and proteins. Riboflavin is a central component of the cofactors FAD and FMN, and is therefore required for the synthesis of all flavoproteins in the body. Flavoproteins play important roles in important roles in the electron transport chain and fatty acid oxidation. In these ways, dietary riboflavin supports healthy energy production in the body.

Vitamin B2 is also known as riboflavin. Riboflavin is a water-soluble vitamin that is found in most animal and plant tissues. The word "ribo" comes from ribose, which is a sugar, and "flavin" means "yellow. " Riboflavin is absorbed in the small intestine and what little is stored in the body is stored in the liver, kidneys, and heart. On the other hand, like most water-soluble vitamins, any excess intake is excreted in urine. Since riboflavin is a yellow compound, excess riboflavin in the urine will make it turn bright yellow.
