In addition to its function as a vitamin, it is used as a food coloring agent. Always discuss any changes to your treatment plan with your healthcare provider. If you have any of the following conditions, riboflavin may not be safe for you.
What is riboflavin (vitamin B ?
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 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.

- Pregnant or lactating women and their infants may also be at risk, if the mother avoids meat and dairy products.
- While more research is needed, these findings suggest that riboflavin may play an important role in supporting long-term eye health.
- 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.
- Riboflavin regulates circulating levels of homocysteine, an amino acid that enters the diet from animal protein foods like meat.
- Riboflavin deficiency appears to impair the metabolism of the dietary mineral, iron, which is essential to the production of hemoglobin and red blood cells.
- Most riboflavin is used immediately and not stored in the body, so excess amounts are excreted in the urine.

Other Questions About Vitamin B2
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.
Cancer
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.
Signs and symptoms
- People with physically demanding lives, such as athletes and laborers, may require higher riboflavin intake.
- There is growing evidence that riboflavin exerts a protective effect against certain types of cancer.
- Riboflavin, also known as vitamin B2, is a vitamin found in food and sold as a dietary supplement.
- In the United States, the Food and Drug Administration (FDA) does not regulate dietary supplements the way it regulates prescription medications.
- Riboflavin deficiency is usually found together with other nutrient deficiencies, particularly of other water-soluble vitamins.
- An excess of dietary riboflavin, usually from supplements, can cause urine to become bright yellow.

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 does vitamin B2 do for my body?
- {
- The National Academy of Medicine updated the Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs) for riboflavin in 1998.
- Riboflavin works to reduce oxidative stress and inflammation of nerves, which are contributors to migraine headaches.
- 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.
- Diseases such as cancer, heart disease and diabetes may cause or exacerbate riboflavin deficiency.
- The PRI during pregnancy is 1.9 mg/day and the PRI for lactating females is 2.0 mg/day.

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 King’s Chip casino 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.

Contraindications for Riboflavin Use

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 – Uses, Side Effects, and More

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.
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.
