Riboflavin, also known as vitamin B2, is a vitamin found in food and used as a dietary supplement. Food sources include eggs, green vegetables, milk and other dairy product, meat, mushrooms, and almonds. Some countries require its addition to grains. As a supplement it is used to prevent and treat riboflavin deficiency and prevent migraines. It may be given by mouth or injection. It is nearly always well tolerated. Normal doses are safe during pregnancy. Riboflavin is in the vitamin B group. It is required by the body for cellular respiration. Riboflavin was discovered in 1920, isolated in 1933, and first made in 1935. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. Riboflavin is available as a generic medication and over the counter. In the United States the supplements of riboflavin is less than 25 USD.

Riboflavin deficiency (ariboflavinosis) results in painful red tongue with sore throat, chapped and fissured lips (cheilosis), and inflammation of the corners of the mouth. There can be oily scaly skin rashes on the lips. The eyes can become itchy, watery, bloodshot and sensitive to light. Due to the interference with iron absorption, even mild to moderate riboflavin deficiency results in normal cell size and normal  content (i.e. normochromic normocytic ). It is different from anemia caused by deficiency of  (B9) or  (B12), which causes anemia with large blood cells. Deficiency of riboflavin during pregnancy can result in birth defects including congenital heart defects and limb deform.
