PRODUCT DETAILS

Unlike standard synthetic Vitamin B2 (Riboflavin), which requires a complex enzymatic conversion in the gastrointestinal tract and liver, R5P is ready for immediate cellular utilization. This direct absorption pathway makes it the premier choice for advanced pharmaceuticals, high-end nutraceuticals, clinical nutrition, and functional infant formulas.
