A 2017 review reported that daily riboflavin taken at 400 mg per day for at least three King’s Chip casino months may reduce the frequency of migraine headaches in adults. Research on high-dose riboflavin for migraine prevention or treatment in children and adolescents is inconclusive, and so supplements are not recommended. Ongoing research is also investigating riboflavin’s potential role in preventing cataracts and age-related macular degeneration (AMD). While more research is needed, these findings suggest that riboflavin may play an important role in supporting long-term eye health. These interactions may affect how well riboflavin or the other medication works, or they could increase the risk of side effects. In the United States, the Food and Drug Administration (FDA) does not regulate dietary supplements the way it regulates prescription medications.
Recent Updates on Riboflavin Research
- {
- RDAs are higher than EARs to provide adequate intake levels for individuals with higher than average requirements.
- Supplementation with riboflavin, folic acid, and vitamin B12 is commonly used to reduce the risk.
- Studies suggest that riboflavin can protect against diabetes-related heart disease due to its potent antioxidant effects.
- Vitamin B2, or riboflavin, is naturally present in foods, added to foods, and available as a supplement.
- Cooking doesn’t destroy riboflavin, so you won’t lose any nutritional benefits whether a food is roasted, fried, boiled, or steamed.
- A table of the old and new adult daily values is provided at Reference Daily Intake.

Because riboflavin assists many enzymes with various daily functions throughout the body, a deficiency can lead to health problems. Animal studies show that the brain and heart disorders and some cancers can develop from long-term riboflavin deficiency. Riboflavin regulates circulating levels of homocysteine, an amino acid that enters the diet from animal protein foods like meat.

- Dietary deficiency of riboflavin can decrease the production of NAD and NADP, thereby promoting niacin deficiency.
- For personalized guidance, consult your healthcare provider, registered dietitian nutritionist (RD or RDN), or pharmacist.
- Rich food sources of riboflavin include some meats, chicken, dairy, vegetables, and fruits.
- However, riboflavin supplementation in large excess of requirements causes urine to appear more yellow than normal.
- 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.
- Riboflavin also helps to maintain normal homocysteine levels which aids in heart health.

Vitamin B2 Side Effects
Riboflavin works with other B vitamins like B6, folate, and B12 to break down homocysteine in the body. However, how riboflavin is regulated and transported in the heart in humans is not clearly understood. Epidemiological studies have not shown that lowering homocysteine levels with B vitamin supplementation reduces the risk of heart attacks or deaths from CVD. The American Heart Association does not advocate for the use of B vitamin supplements for reducing CVD risk. Even better, the children saw a decrease in migraine pain for up to 18 months after they stopped taking riboflavin supplements.
Riboflavin – Uses, Side Effects, and More
Always consult your healthcare provider before starting or adjusting your dose. There is growing evidence that riboflavin exerts a protective effect against certain types of cancer. A diet rich in vitamin B2 and other B-complex vitamins may lower your risk of cataracts.
- {
- There are rare genetic defects that compromise riboflavin absorption, transport, metabolism or use by flavoproteins.
- Riboflavin deficiency is rare in developed countries but can occasionally occur.
- The assessment of riboflavin status is essential for confirming cases with non-specific symptoms whenever deficiency is suspected.
- For U.S. food and dietary supplement labeling purposes the amount in a serving is expressed as a percent of Daily Value (%DV).
- In addition to its function as a vitamin, it is used as a food coloring agent.
- While rare, induced light sensitivity can increase the risk of eye damage from direct sun exposure.

Possible Side Effects
With a GoodRx coupon, a 30-day supply of riboflavin (100 mg tablets) typically ranges from $5 to $15 without insurance. Yes, riboflavin is not only safe but also essential for both maternal health and the infant’s growth and development. Breastfeeding mothers may require slightly higher amounts of riboflavin, but excessive supplementation should be avoided. Yes, riboflavin (Vitamin B2) is generally safe when taken in recommended amounts. However, it’s important to avoid high doses unless specifically advised by a healthcare provider. It is commonly used to manage various conditions, including migraines, anemia, and certain skin disorders.
Dietary Sources
An EGRAC of 1.0 to 1.2 indicates that adequate amounts of riboflavin are present; 1.2 to 1.4 is considered low, greater than 1.4 indicates deficient. Urinary excretion load tests have been used to determine dietary requirements. Dietary deficiency of riboflavin can decrease the production of NAD and NADP, thereby promoting niacin deficiency. Conversion of vitamin B6 to its coenzyme, pyridoxal 5′-phosphate, involves the enzyme, pyridoxine 5′-phosphate oxidase, which requires FMN. Unlike folate and vitamin B6, which occur in several chemically related forms known as vitamers, riboflavin is only one chemical compound.
