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.

- 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 PRI during pregnancy is 1.9 mg/day and the PRI for lactating females is 2.0 mg/day.
- 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 National Academy of Medicine updated the Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs) for riboflavin in 1998.

Vitamin K: How Much Do You Need?
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.
Contraindications for Riboflavin Use
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.
Pharmacologic Category of Riboflavin
{
- While more research is needed, these findings suggest that riboflavin may play an important role in supporting long-term eye health.
- Riboflavin works with other B vitamins like B6, folate, and B12 to break down homocysteine in the body.
- Riboflavin regulates circulating levels of homocysteine, an amino acid that enters the diet from animal protein foods like meat.
- Most riboflavin is used immediately and not stored in the body, so excess amounts are excreted in the urine.
- 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.

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.
Recent Updates on Riboflavin Research
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.
- 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.
- People with physically demanding lives, such as athletes and laborers, may require higher riboflavin intake.
- Animal studies show that the brain and heart disorders and some cancers can develop from long-term riboflavin deficiency.
- Riboflavin deficiency is usually found together with other nutrient deficiencies, particularly of other water-soluble vitamins.

Most riboflavin is used immediately and not stored in the body, so excess amounts are excreted in the urine. An excess of dietary riboflavin, King’s Chip casino usually from supplements, can cause urine to become bright yellow. In the early 1900s, several research laboratories were investigating constituents of foods, essential to maintain growth in rats.

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 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.
