Definition: Riboflavin, or vitamin B2 is a member of the water-soluble family of B-Complex vitamins. It's required for glucose metabolism so your body can produce energy from carbohydrates, normal red blood cell production and general body growth. Deficiency is rare.

Riboflavin is found naturally in lean meats, eggs, leafy green vegetables, nuts, legumes, fortified breads and cereals, milk and dairy products. Riboflavin is sensitive to light, so foods rich in riboflavin should not be stored in clear containers exposed to light. Riboflavin intake is usually adequate in a normal diet so supplementation should not be necessary.
