Interactions
synergistic. Riboflavin (as FMN/FAD) is required for NADPH-dependent reductases that mobilize iron from ferritin stores; B2 deficiency impairs iron absorption and utilization
synergistic. FMN (from riboflavin) is the cofactor for pyridoxine 5-phosphate oxidase, which converts B6 to its active form (PLP); B2 deficiency functionally limits B6 activity
enhances. Riboflavin 400mg/day is an evidence-based migraine prophylaxis (improves mitochondrial energy metabolism); may enhance or allow dose reduction of conventional preventives
competes. Methotrexate inhibits dihydrofolate reductase; riboflavin is involved in folate metabolism via MTHFR, and B2 deficiency may worsen methotrexate-induced folate depletion
