A deficiency of riboflavin can lead to cracking and reddening of the lips, inflammation of the mouth, mouth ulcers, sore throat, and even iron deficiency anemia. Riboflavin, Vitamin B2, is a water-soluble vitamin that is well regulated by the body, thus overdose is rare, and usually only occurs with vitamin B2 injections or supplements. The current DV for Riboflavin (Vitamin B2) is 1.7mg.
Food and beverages that provide riboflavin without fortification are eggs, leaf vegetables, legumes, mushrooms, and almonds.
Riboflavin is also used as a food coloring and as such is designated in Europe as the E number E101.
