Riboflavin supplements for blood pressure lowering in adults
The Cochrane database of systematic reviews (2025) · Meta analysis · n=320
The evidence for the effect of oral riboflavin supplements on systolic and diastolic blood pressure is very uncertain.
Based on meta-analysis showing significant reduction in migraine frequency, days, duration, and pain score. High heterogeneity (I2=65-89%) in pooled analyses suggests variable individual responses. Most studies used 400mg daily dose.
