Riboflavin (Vitamin B2)


Riboflavin, also known as vitamin B2, is an essential nutrient that plays a crucial role in various bodily functions. It is water-soluble and belongs to the B-complex group of vitamins. Riboflavin is primarily involved in energy metabolism, cell growth, and the production of red blood cells.


Riboflavin has numerous health benefits and is commonly used for:

  • Energy Production: Riboflavin is an essential component of two coenzymes, FAD (flavin adenine dinucleotide) and FMN (flavin mononucleotide), which serve as electron carriers in energy-producing reactions.
  • Cell Growth and Repair: Riboflavin is involved in the synthesis of proteins and nucleic acids, which are essential for cell growth and repair.
  • Red Blood Cell Production: Riboflavin is necessary for the production of red blood cells (erythrocytes), which carry oxygen throughout the body.
  • Eye Health: Riboflavin is essential for maintaining healthy vision and preventing conditions such as cataracts and macular degeneration.
  • Skin Health: Riboflavin helps maintain healthy skin by promoting collagen production and cell renewal.
  • Migraine Prevention: Studies have shown that riboflavin may help reduce the frequency and severity of migraines.

Dietary Sources

Riboflavin is found in various foods, including:

  • Meat and poultry
  • Fish and seafood
  • Eggs
  • Dairy products
  • Fortified cereals
  • Leafy green vegetables

Recommended Intake

The daily recommended intake of riboflavin varies depending on age, sex, and health status. The recommended dietary allowance (RDA) for adults is:

  • 1.3 mg/day for women
  • 1.7 mg/day for men


Riboflavin supplements are available in tablet, capsule, and liquid forms. They may be recommended for individuals who have difficulty obtaining sufficient amounts from their diet or have increased needs due to certain medical conditions.

Side Effects

Riboflavin is generally well-tolerated. However, high doses (over 100 mg/day) may cause:

  • Nausea
  • Vomiting
  • Diarrhea
  • Yellow-orange urine


  • Pregnancy and Breastfeeding: Riboflavin is considered safe for use during pregnancy and breastfeeding. However, it is essential to consult a healthcare professional before taking supplements.
  • Riboflavin Intolerance: Some individuals may have a rare intolerance to riboflavin, which can cause itching, hives, or swelling.
  • Drug Interactions: Riboflavin may interact with certain medications, such as antibiotics and antidepressants. It is important to inform your doctor about all medications you are taking before using riboflavin supplements.


The appropriate dosage of riboflavin supplements depends on individual needs and should be determined by a healthcare professional. Typical recommended doses range from 10 mg to 50 mg per day.


Riboflavin is an essential vitamin that plays a vital role in energy metabolism, cell growth, red blood cell production, and overall health. It is found in various food sources and available as supplements for individuals who do not get enough from their diet. While riboflavin is generally safe, it is essential to consult a healthcare professional before taking supplements to determine the appropriate dosage and address any potential side effects or interactions.
