Vitamin B2, also known as riboflavin, is one of the eight B-complex vitamins. Like other B vitamins, it plays a role in energy production in the body, but also has many other important uses.
Vitamin B2 is a water-soluble vitamin that is flushed out of the body daily, so it must be restored each day. The best way to get this vitamin is by eating foods that are rich in riboflavin. Riboflavin is found in eggs, nuts, dairy products, meats, broccoli, brewer's yeast, Brussel sprouts, wheat germ, wild rice, mushrooms, soybeans, green leafy vegetables and whole grain and enriched cereals and bread.
Riboflavin is a vitamin that is needed for growth and overall good health. It helps the body break down carbohydrates, proteins and fats to produce energy, and it allows oxygen to be used by the body.
Vitamin B2 is also important for eye health. According to the University of Michigan, this vitamin is needed to protect glutathione, which is an important antioxidant in the eye. The U.S. National Library of Medicine (NLM) reports that eating a diet rich in riboflavin can lower the risk of developing cataracts. Taking supplements containing riboflavin and niacin may also be helpful in preventing cataracts.
