A toxic level of riboflavin has not been observed from food sources and supplements. Therefore, a Tolerable Upper Intake Level for riboflavin has not been established. The earliest reported identification, predating any concept of vitamins as essential nutrients, was by Alexander Wynter Blyth.
Signs and symptoms
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.
- Riboflavin deficiency is usually found together with other nutrient deficiencies, particularly of other water-soluble vitamins.
- Vitamin B2 supplements are available as tablets, capsules, effervescent, and liquids.
- Animal studies show that the brain and heart disorders and some cancers can develop from long-term riboflavin deficiency.
- An excess of dietary riboflavin, usually from supplements, can cause urine to become bright yellow.
- Riboflavin works to reduce oxidative stress and inflammation of nerves, which are contributors to migraine headaches.
- Riboflavin, also known as vitamin B2, is a vitamin found in food and sold as a dietary supplement.

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.
Food Sources
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.
Cancer
- If you have any of the following conditions, riboflavin may not be safe for you.
- There is growing evidence that riboflavin exerts a protective effect against certain types of cancer.
- In humans, there is no evidence for riboflavin toxicity produced by excessive intakes and absorption becomes less efficient as dosage increases.
- In the United States, the Food and Drug Administration (FDA) does not regulate dietary supplements the way it regulates prescription medications.
- People with physically demanding lives, such as athletes and laborers, may require higher riboflavin intake.

- Riboflavin deficiency appears to impair the metabolism of the dietary mineral, iron, which is essential to the production of hemoglobin and red blood cells.
- 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.
- The National Academy of Medicine updated the Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs) for riboflavin in 1998.
- Riboflavin regulates circulating levels of homocysteine, an amino acid that enters the diet from animal protein foods like meat.

Riboflavin (Vitamin B : Benefits, Uses, and Dosage Guidelines
Natural sources of riboflavin include meat, fish and fowl, eggs, dairy products, green vegetables, mushrooms, and almonds.

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.
