It belongs to the B-complex group and plays a crucial role in cellular energy production. Riboflavin acts as a precursor to two key coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes participate in oxidation-reduction reactions necessary for metabolizing carbohydrates, fats, and proteins.\u003c\/p\u003e\u003cp\u003eThis Source Naturals supplement provides 100 mg of riboflavin per tablet, a dose significantly higher than the recommended daily intake, ideal for those seeking an additional supply.

The inactive form requires conversion in the body, while the active form is ready for use. Both are effective, although the active form may be more bioavailable for some people.\u003c\/p\u003e\u003cp\u003eIt is recommended to take 1 tablet daily with food to facilitate absorption.
