A cofactor in the FAD and FMN energy-producing pathways and in antioxidant recycling. Also required for the conversion of B6 and folate into their active forms.
Why this form
Free-form riboflavin is the most readily absorbed state of vitamin B2 — direct uptake through intestinal flavin transporters without requiring prior separation from protein-bound forms found in food.
Key benefits
Energy production pathways
Riboflavin is the precursor to FAD and FMN — two coenzymes central to the electron transport chain and dozens of oxidation-reduction reactions involved in carbohydrate, fat and protein metabolism.
B-vitamin activation
Riboflavin is required for the activation of vitamin B6 into its active P5P form and for the conversion of folate into its active coenzyme forms — making adequate B2 a prerequisite for the full B-complex network.
Antioxidant recycling
Riboflavin is a cofactor for glutathione reductase, the enzyme that regenerates reduced glutathione — the cell's primary water-soluble antioxidant — enabling continuous antioxidant defence.
