What does the vitamin B-2 do?
Riboflavin (E101), also known as vitamin B2, 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. Like the other B vitamins, it plays a key role in energy metabolism, and is required for the metabolism of fats, ketone bodies, carbohydrates, and proteins. Milk, cheese, leafy green vegetables, liver, kidneys, legumes such as mature soybeans,[1] yeast, and almonds[citation needed] are good sources of vitamin B2, but exposure to light destroys riboflavin. The name “riboflavin” comes from “ribose” and “flavin”. Riboflavin is not toxic when taken orally, as its low solubility keeps it from being absorbed in dangerous amounts from the gut [2]. Although toxic doses can be administered by injection[2], any excess at nutritionally relevant doses is excreted in the urine[3], i
