In 1938, Richard Kuhn was awarded the Nobel Prize in Chemistry for his work on vitamins, which had included B2 and B6. Women fed a diet low in riboflavin developed stomatitis and other signs of deficiency, which were reversed when treated with synthetic riboflavin. Riboflavin deficiency is usually found together with other King’s Chip casino nutrient deficiencies, particularly of other water-soluble vitamins. Secondary deficiencies are typically caused by the body not being able to use the vitamin, or by an increased rate of excretion of the vitamin. Diseases such as cancer, heart disease and diabetes may cause or exacerbate riboflavin deficiency. Riboflavin deficiency is rare and is usually accompanied by deficiencies of other vitamins and nutrients.
Estimated Cost of Riboflavin Supplements
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.
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.
Treatment of corneal thinning
Cows’ milk contains mainly free riboflavin, but both FMN and FAD are present at low concentrations. As always, consult your healthcare provider before making any changes to your treatment plan. Vitamin B2 supplements are available as tablets, capsules, effervescent, and liquids. While rare, induced light sensitivity can increase the risk of eye damage from direct sun exposure. Supplementation with riboflavin, folic acid, and vitamin B12 is commonly used to reduce the risk.
- {
- Most riboflavin is used immediately and not stored in the body, so excess amounts are excreted in the urine.
- Riboflavin regulates circulating levels of homocysteine, an amino acid that enters the diet from animal protein foods like meat.
- The National Academy of Medicine updated the Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs) for riboflavin in 1998.
- Secondary deficiencies are typically caused by the body not being able to use the vitamin, or by an increased rate of excretion of the vitamin.
- While more research is needed, these findings suggest that riboflavin may play an important role in supporting long-term eye health.
- Riboflavin deficiency appears to impair the metabolism of the dietary mineral, iron, which is essential to the production of hemoglobin and red blood cells.

Riboflavin – Uses, Side Effects, and More

- The cost of a 30-day supply of riboflavin supplements can vary depending on the brand and dosage.
- The enrichment of bread and ready-to-eat breakfast cereals contributes significantly to the dietary supply of the vitamin.
- Riboflavin works with other B vitamins like B6, folate, and B12 to break down homocysteine in the body.
- The RDA is the intake that meets the nutrient requirements of 97% to 98% of the U.S. population.
- Pregnant or lactating women and their infants may also be at risk, if the mother avoids meat and dairy products.
- 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.

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 is naturally present in animal-sourced foods along with protein-bound FMN and FAD.
Food Sources
- Riboflavin works to reduce oxidative stress and inflammation of nerves, which are contributors to migraine headaches.
- Riboflavin deficiency is usually found together with other nutrient deficiencies, particularly of other water-soluble vitamins.
- Animal studies show that the brain and heart disorders and some cancers can develop from long-term riboflavin deficiency.
- Vitamin B2 supplements are available as tablets, capsules, effervescent, and liquids.
- The PRI during pregnancy is 1.9 mg/day and the PRI for lactating females is 2.0 mg/day.
- Diseases such as cancer, heart disease and diabetes may cause or exacerbate riboflavin deficiency.

If the vitamin is exposed to too much light, it can be deactivated from its usable form. The PRI during pregnancy is 1.9 mg/day and the PRI for lactating females is 2.0 mg/day. For children aged 1–14 years the PRIs increase with age from 0.6 to 1.4 mg/day.
Pharmacologic Category of Riboflavin
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.

Health Benefits of Riboflavin (Vitamin B
|}
In the case of riboflavin there is no UL, as there is no human data for adverse effects from high doses. Riboflavin deficiency appears to impair the metabolism of the dietary mineral, iron, which is essential to the production of hemoglobin and red blood cells. Cooking doesn’t destroy riboflavin, so you won’t lose any nutritional benefits whether a food is roasted, fried, boiled, or steamed. Most offer between 25mg and 100mg of riboflavin, only a small amount of which is absorbed in the intestines. Scientists believe that certain cancers, like esophageal and cervical cancers, may be avoided by stabilizing the structure of cellular DNA.
People with riboflavin in their diet have a lower risk of developing cataracts. Riboflavin exerts potent anti-inflammatory effects that appear to temper the overreactive immune response. Studies suggest that riboflavin can protect against diabetes-related heart disease due to its potent antioxidant effects. Riboflavin also helps to maintain normal homocysteine levels which aids in heart health. Riboflavin may also ease stress and minimize nerve inflammation that contributes to migraines.

What to Know Before You Take Herbal Supplements

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.
