How Vitamin B2 Works

Like many scientific discoveries, vitamin B2 was discovered almost accidentally. In the 1920s and 1930s, nutritionists were searching for a growth-promoting factor in food. Their search kept turning up yellow substances. Meanwhile, biochemists who were busy trying to solve the mysteries of metabolism kept encountering a yellow enzyme. The yellow substances in food and the enzyme that the researchers kept encountering were all riboflavin. In this article, we'll learn why vitamin B2, or riboflavin, is important and how to get enough of it in your diet. Here's a preview.
  • What Is Vitamin B2?

    Vitamin B2, or riboflavin, works together with the family of B-complex vitamins to provide the body with energy by metabolizing carbohydrates, fats, and proteins. It also helps in the regeneration of glutathione, an enzyme that rids the body of free radicals.

  • Benefits of Vitamin B2

    Riboflavin may be able to decrease the number of migraine headaches a person has. It might also help to prevent cataracts. Riboflavin has helped to increase iron levels for those suffering from iron-deficiency anemia.

  • Foods That Contain Vitamin B2

    Dairy products, such as milk, cheese, and yogurt, are excellent sources of riboflavin. Some meats and leafy green vegetables are also rich in this nutrient. "Enriched" breads and cereals have had riboflavin added to them.

  • Vitamin B2 Deficiency

    Hypersensitivity to light can be a sign of a riboflavin deficiency, which causes the skin to become greasy, scaly, and dry. A riboflavin deficiency might contribute to cataracts, so those who have suffered from cataracts in the past should consider a riboflavin supplement.
