From the Guidelines

The recommended riboflavin dosage for migraines is 400 mg per day. This dosage is based on the available evidence, although the provided study from 2002 1 does not specifically mention the optimal dosage of riboflavin for migraine prevention. However, it does acknowledge that riboflavin, along with other agents like feverfew, magnesium, and hormone therapy, has fair evidence for modest efficacy in certain circumstances. When considering riboflavin for migraine prevention, it's essential to:

  • Take the supplement with food to improve absorption and reduce potential stomach upset
  • Be patient, as it generally takes at least 3 months of consistent use to determine effectiveness
  • Monitor for minimal side effects, which can include bright yellow urine, mild diarrhea, or increased urination Key points to consider:
  • Riboflavin works by improving mitochondrial function and energy metabolism in brain cells
  • It is considered a safe option with few drug interactions, making it appropriate for many patients, including those who cannot tolerate prescription preventive medications
  • If you're currently taking other medications for migraine prevention, continue them while adding riboflavin unless advised otherwise by your healthcare provider.

From the Research

Riboflavin Dosage for Migraines

  • The optimal dosage of riboflavin for migraines is not universally established, but studies have investigated its efficacy in migraine prophylaxis.
  • A study published in 2004 2 used a dosage of 400 mg riboflavin per day and found a significant reduction in headache frequency.
  • Another study from 2015 3 used a proprietary supplement containing a fixed combination of magnesium, riboflavin, and Q10, but the exact dosage of riboflavin is not specified.
  • The evidence suggests that riboflavin is a safe and well-tolerated alternative in migraine prophylaxis, but more studies are needed to determine the optimal dosage.

Efficacy of Riboflavin in Migraine Prophylaxis

  • Studies have shown that riboflavin can reduce headache frequency and intensity, as well as the use of abortive drugs 2, 3.
  • A review of preventive migraine treatment published in 2015 4 lists riboflavin as a treatment with strong evidence for use in migraine prevention.
  • Another review from 2006 5 notes that there is limited evidence to support the use of riboflavin in migraine prevention, but it can be considered when other medications cannot be used.

Combination Therapy with Riboflavin

  • The study from 2015 3 investigated the efficacy of a proprietary supplement containing a fixed combination of magnesium, riboflavin, and Q10, and found a statistically significant reduction in migraine symptoms and burden of disease.
  • This suggests that combination therapy with riboflavin may be effective in migraine prophylaxis, but more studies are needed to confirm these findings.
