Natural Factors BioCoenzymated Riboflavin 5'-Phosphate 50 mg is formulated with Riboflavin 5-Phosphate (R-5-P), which is the active coenzyme form of vitamin B2. This form is superior to standard Riboflavin for many individuals, as it bypasses the need for enzymatic conversion in the body, ensuring more efficient absorption and utilization. This makes it particularly effective for its stated goals of energy production, as Riboflavin is a key component of FAD and FMN, coenzymes essential for the electron transport chain. Nutritionists often recommend coenzymated forms for better bioavailability, especially for those with genetic variations or health conditions that might impair this conversion. Online reviews generally praise its efficacy, with a high review count (7310) suggesting broad user satisfaction. However, the advanced form and brand reputation come at a higher price per serving ($27) compared to conventional Riboflavin supplements.
