From the Research
The recommended daily dosage of vitamin B2 (riboflavin) for adults is 1.1 mg for women and 1.3 mg for men, but for migraine prophylaxis, a dosage of 400 mg/day has been shown to be effective in reducing migraine days, duration, frequency, and pain score 1. When considering the daily dosage of vitamin B2, it's essential to differentiate between the general recommended daily intake and the dosage required for specific health conditions, such as migraine prophylaxis. The general recommended daily intake of vitamin B2 can be obtained through a balanced diet that includes milk, eggs, fortified cereals, lean meats, and green vegetables. However, for individuals suffering from migraines, a higher dosage of vitamin B2 may be necessary to achieve therapeutic benefits.
Some key points to consider:
- Vitamin B2 is essential for energy production, cell function, and metabolism of fats, drugs, and steroids 2.
- Most people get sufficient B2 from their diet, but supplementation may be necessary for those with certain health conditions, poor nutrition, or increased needs.
- Taking more than the recommended amount is generally unnecessary as excess B2 is excreted in urine, giving it a characteristic bright yellow color.
- The effectiveness of vitamin B2 supplementation in migraine prophylaxis has been demonstrated in several studies, with a meta-analysis showing a significant decrease in migraine days, duration, frequency, and pain score 1.
- The recommended daily intake values of vitamins, including vitamin B2, have been established based on studies of dependence of vitamins contents in blood serum from daily consumption of vitamins 3.
In terms of specific dosage recommendations, the study by 1 found that a dosage of 400 mg/day of vitamin B2 for three months had a significant effect on migraine prophylaxis. This dosage is significantly higher than the general recommended daily intake of 1.1 mg for women and 1.3 mg for men. However, it's essential to note that this higher dosage is specifically for migraine prophylaxis and may not be necessary for general health and wellness.
Overall, the recommended daily dosage of vitamin B2 for adults is 1.1 mg for women and 1.3 mg for men, but for migraine prophylaxis, a dosage of 400 mg/day has been shown to be effective in reducing migraine days, duration, frequency, and pain score 1.
