Riboflavin is a B vitamin. It can be found in certain foods such as milk, meat, eggs, nuts, enriched flour, and green vegetables. Riboflavin is frequently used in combination with other B vitamins in vitamin B complex products.
Originally called lactochrome, it was also once known as vitamin G. Riboflavin is important for energy production, enzyme function, and normal fatty acid and amino acid synthesis and is necessary for the reproduction of glutathione, a free radical scavenger.
