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.
Key Points About Riboflavin (Vitamin B
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.
Diabetes and Heart Health
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.
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 King’s Chip casino 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.

- Even better, the children saw a decrease in migraine pain for up to 18 months after they stopped taking riboflavin supplements.
- 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.
- When untreated, infants with riboflavin transporter deficiency have labored breathing and are at risk of dying in the first decade of life.
- The erythrocyte glutathione reductase activity coefficient (EGRAC) provides a measure of tissue saturation and long-term riboflavin status.
- As always, consult your healthcare provider before making any changes to your treatment plan.
- Riboflavin may also ease stress and minimize nerve inflammation that contributes to migraines.
- One of these is riboflavin transporter deficiency, previously known as Brown–Vialetto–Van Laere syndrome.

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.
- 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.
- Dietary deficiency of riboflavin can decrease the production of NAD and NADP, thereby promoting niacin deficiency.
- 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.

Dietary recommendations

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.
