This B vitamin works as an antioxidant to help fight free radicals (particles in the body that damage cells) and may prevent early aging and the development of heart disease. Riboflavin is also important for red blood cell production, which is necessary for transporting oxygen throughout the body. Several studies suggest B2 can help stave off migraines, but more research is needed to be sure. And be careful, while sunlight does the body good, ultraviolet light reduces the riboflavin content in food sources. Milk, for instance, is best purchased in opaque containers in order to keep this vitamin from breaking down.
