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.

- While rare, induced light sensitivity can increase the risk of eye damage from direct sun exposure.
- Cows’ milk contains mainly free riboflavin, but both FMN and FAD are present at low concentrations.
- Urine color is used as a hydration status biomarker and, under normal conditions, correlates with urine specific gravity and urine osmolality.
- Riboflavin is prescribed to treat corneal thinning, and taken orally, may reduce the incidence of migraine headaches in adults.
- It is commonly used to manage various conditions, including migraines, anemia, and certain skin disorders.

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.
Vitamin B2 Side Effects
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.
