There are rare genetic defects that compromise riboflavin absorption, transport, metabolism or use by flavoproteins. One of these is riboflavin transporter deficiency, previously known as Brown–Vialetto–Van Laere syndrome. When untreated, infants with riboflavin transporter deficiency have labored breathing and are at risk of dying in the first decade of life. People at risk of having low riboflavin levels include alcoholics, vegetarian athletes, and practitioners of veganism. Pregnant or lactating women and their infants may also be at risk, if the mother avoids meat and dairy products. People with physically demanding lives, such as athletes and laborers, may require higher riboflavin intake.
Vitamin B2 Side Effects
- If the vitamin is exposed to too much light, it can be deactivated from its usable form.
- People with riboflavin in their diet have a lower risk of developing cataracts.
- Therefore, a Tolerable Upper Intake Level for riboflavin has not been established.
- A diet rich in vitamin B2 and other B-complex vitamins may lower your risk of cataracts.
- In 1938, Richard Kuhn was awarded the Nobel Prize in Chemistry for his work on vitamins, which had included B2 and B6.
- Natural sources of riboflavin include meat, fish and fowl, eggs, dairy products, green vegetables, mushrooms, and almonds.

Natural sources of riboflavin include meat, fish and fowl, eggs, dairy products, green vegetables, mushrooms, and almonds. It can also help prevent or treat migraines, certain cancers, cataracts, preeclampsia, seizures, and dementia. If tests show you need more B2, head to the store and stock up on leafy greens, lean meats, dairy products and other riboflavin-rich foods.
Signs and symptoms
{
- For children aged 1–14 years the PRIs increase with age from 0.6 to 1.4 mg/day.
- People at risk of having low riboflavin levels include alcoholics, vegetarian athletes, and practitioners of veganism.
- Riboflavin deficiency is rare and is usually accompanied by deficiencies of other vitamins and nutrients.
- It is commonly used to manage various conditions, including migraines, anemia, and certain skin disorders.
- Cows’ milk contains mainly free riboflavin, but both FMN and FAD are present at low concentrations.
- The American Heart Association does not advocate for the use of B vitamin supplements for reducing CVD risk.

For personalized guidance, consult your healthcare provider, registered dietitian nutritionist (RD or RDN), or pharmacist. The assessment of riboflavin status is essential for confirming cases with non-specific symptoms whenever deficiency is suspected. When excess riboflavin is absorbed by the small intestine, it is quickly removed from the blood and excreted in urine. Urine color is used as a hydration status biomarker and, under normal conditions, correlates with urine specific gravity and urine osmolality. However, riboflavin supplementation in large excess of requirements causes urine to appear more yellow than normal.
Side Effects
Riboflavin, also known as vitamin B2, is a vitamin found in food and sold as a dietary supplement. Riboflavin is prescribed to treat corneal thinning, and taken orally, may reduce the incidence of migraine headaches in adults. The cost of a 30-day supply of riboflavin supplements can vary depending on the brand and dosage.
- Yes, riboflavin is not only safe but also essential for both maternal health and the infant’s growth and development.
- However, it’s important to avoid high doses unless specifically advised by a healthcare provider.
- It can also help prevent or treat migraines, certain cancers, cataracts, preeclampsia, seizures, and dementia.
- These interactions may affect how well riboflavin or the other medication works, or they could increase the risk of side effects.
- Epidemiological studies have not shown that lowering homocysteine levels with B vitamin supplementation reduces the risk of heart attacks or deaths from CVD.
- FAD contributes to the conversion of tryptophan to niacin (vitamin B3) and the conversion of vitamin B6 to the coenzyme pyridoxal 5′-phosphate requires FMN.

Recommended Amounts
Riboflavin deficiency is rare in developed countries but can occasionally occur. Rich food sources of riboflavin include some meats, chicken, dairy, vegetables, and fruits. Vitamin B2, or riboflavin, is naturally present in foods, added to foods, and available as a supplement.
Eye Fatigue
The white flour produced after milling of wheat has only 67% of its original riboflavin amount left, so white flour is enriched in some countries. The enrichment of bread and ready-to-eat breakfast cereals contributes significantly to the dietary supply of the vitamin. Free riboflavin King’s Chip casino is naturally present in animal-sourced foods along with protein-bound FMN and FAD.
