Rarely, very high doses may cause mild gastrointestinal discomfort. Individuals with certain metabolic disorders should consult a healthcare professional before taking high-dose riboflavin.

How is riboflavin different from other B vitamins?

Riboflavin (vitamin B2) specifically helps form the coenzymes FMN and FAD, which are crucial for the energy production pathways in cells.
