Community experiences
Selected positive personal experiences from external communities, edited and summarized. These accounts do not establish effectiveness.
A contributor taking riboflavin felt it helped when used consistently, because migraine days became more frequent when they stopped. They said they noticed little difference after reducing the dose themselves, but were also taking magnesium and CoQ10 every day. They also mentioned bright yellow urine; this personal account does not establish B2's contribution alone or an appropriate dose.
Experience shared by external community contributor A
A contributor bothered by frequent mouth ulcers wrote that the pain eased about two or three days after starting a B2 product. About a week later, they reported no pain when eating or when their toothbrush touched the area. They did not state their dose or whether they used other care measures, and provided no tests establishing the cause of the ulcers or B2 deficiency.
