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.
How to Choose Supplements
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.
Recent Updates on Riboflavin Research
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.

- Always discuss any changes to your treatment plan with your healthcare provider.
- In humans, there is no evidence for riboflavin toxicity produced by excessive intakes and absorption becomes less efficient as dosage increases.
- Free riboflavin is naturally present in animal-sourced foods along with protein-bound FMN and FAD.
- If you have any of the following conditions, riboflavin may not be safe for you.
- Because riboflavin assists many enzymes with various daily functions throughout the body, a deficiency can lead to health problems.
- There is growing evidence that riboflavin exerts a protective effect against certain types of cancer.

Migraines
- 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.
- Women fed a diet low in riboflavin developed stomatitis and other signs of deficiency, which were reversed when treated with synthetic riboflavin.
- Research on high-dose riboflavin for migraine prevention or treatment in children and adolescents is inconclusive, and so supplements are not recommended.
- Scientists believe that certain cancers, like esophageal and cervical cancers, may be avoided by stabilizing the structure of cellular DNA.
- Most offer between 25mg and 100mg of riboflavin, only a small amount of which is absorbed in the intestines.
- Any excess riboflavin is excreted via the kidneys into urine, resulting in a bright yellow color known as flavinuria.

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.
Functions
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 King’s Chip casino 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.
Dietary recommendations
- Breastfeeding mothers may require slightly higher amounts of riboflavin, but excessive supplementation should be avoided.
- The earliest reported identification, predating any concept of vitamins as essential nutrients, was by Alexander Wynter Blyth.
- Riboflavin exerts potent anti-inflammatory effects that appear to temper the overreactive immune response.
- In the case of riboflavin there is no UL, as there is no human data for adverse effects from high doses.
- Yes, riboflavin (Vitamin B2) is generally safe when taken in recommended amounts.
- As for safety, the IOM sets tolerable upper intake levels (ULs) for vitamins and minerals when evidence is sufficient.

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.

A 2017 review reported that daily riboflavin taken at 400 mg per day for at least three 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.
