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.
This B vitamin works as an antioxidant to help fight free radicals (particles in the body that damage cells). It may also prevent early aging and the development of heart disease. And, riboflavin is important for red blood cell production, which is necessary for transporting oxygen throughout the body.
