Riboflavin (B2)
Precursor to FMN and FAD - the flavin coenzymes that carry electrons through the mitochondrial electron transport chain. Also required to recycle oxidised glutathione back to its active form. 1.4mg = 100% NRV.
Mechanism
Riboflavin is converted in the body to flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) - the flavin coenzymes required by the mitochondrial electron transport chain at Complexes I and II. These coenzymes carry electrons from NADH and FADH2 into the chain, driving the proton gradient that powers ATP synthase.
Critically, riboflavin is also required for glutathione reductase - the enzyme that regenerates reduced glutathione (GSH) from oxidised glutathione (GSSG). Without adequate FAD, the entire glutathione antioxidant cycle slows - directly linking riboflavin status to the effectiveness of the NAC and alpha-lipoic acid in this formula.
Key Benefits
- Precursor to FMN and FAD - required for electron transport chain
- Enables glutathione recycling via glutathione reductase
- Required for fatty acid beta-oxidation
- Supports red blood cell production
- 1.4mg = 100% NRV

Any time of day with food. Riboflavin is light-sensitive; keep the formula away from direct sunlight. Urine turns bright yellow - this is normal and harmless.
