Vitamin B2, also known as riboflavin, is one of the B-complex vitamins and plays several important roles in the body. Its primary uses and benefits include:

  1. Energy Production: Riboflavin is essential for the metabolism of carbohydrates, fats, and proteins. It helps convert these macronutrients into adenosine triphosphate (ATP), the body's primary source of energy. Without sufficient riboflavin, energy production can be impaired, leading to fatigue and weakness.
  2. Skin and Eye Health: Riboflavin is involved in maintaining the health of the skin, eyes, and mucous membranes. It can help prevent or alleviate conditions like cracked lips (cheilosis), redness and inflammation of the tongue (magenta tongue), and inflammation of the corners of the mouth (angular stomatitis).
  3. Antioxidant Function: Riboflavin contributes to the body's antioxidant defenses. It helps in the regeneration of other antioxidants, such as glutathione, which protect cells and tissues from damage by free radicals.
  4. Red Blood Cell Production: Riboflavin is essential for the formation of red blood cells, which are responsible for carrying oxygen throughout the body. A deficiency in riboflavin can lead to a type of anemia known as normocytic anemia.
  5. Nervous System Function: Riboflavin is important for the proper functioning of the nervous system. It helps maintain healthy nerve cells and supports the transmission of nerve signals.
  6. Growth and Development: Adequate riboflavin intake is crucial for normal growth and development, especially in children and adolescents.
  7. Migraine Prevention: Some individuals have reported a reduction in the frequency and severity of migraines with riboflavin supplementation. However, further research is needed to establish a clear link between riboflavin and migraine prevention.
  8. Iron Absorption: Riboflavin may enhance the absorption of non-heme iron, the type of iron found in plant-based foods. This can be beneficial for individuals at risk of iron-deficiency anemia.

Riboflavin is water-soluble, meaning it is not stored in the body, and any excess is excreted in urine. Therefore, it needs to be obtained regularly through the diet. Good food sources of riboflavin include dairy products, eggs, lean meats, leafy green vegetables, and whole grains.

Riboflavin deficiency is uncommon in developed countries due to the presence of this vitamin in a wide variety of foods. However, it can occur in individuals with poor dietary habits, certain medical conditions that affect absorption, or those who are at risk due to factors like excessive alcohol consumption. In cases of deficiency or when additional riboflavin is needed, supplements may be recommended by healthcare professionals.
