China Suppliers Factory Riboflavin Sodium Phosphate - Water-Soluble Vitamin B2 R5P Crystalline Powder
C17H24N4NaO11P
Description
Riboflavin Sodium Phosphate (R5P) is an active phosphate derivative of vitamin B2 (riboflavin). It significantly improves water solubility and bioavailability through modification of phosphate groups. Its technical advantages and nutritional and health value far exceed ordinary riboflavin.
Comparison of Technical Advantages
-
💧
Absorption & Utilization Rate Increased The solubility of riboflavin sodium phosphate in water reaches 50 mg/mL — dozens of times that of ordinary riboflavin. It can be formulated into injections, eye drops, and more, breaking the oral-only limitation of regular riboflavin and significantly expanding clinical application scenarios.
-
⚡
Enhanced Metabolic Activity As a precursor of coenzymes FAD and FMN, it directly participates in the energy metabolism of the cell respiratory chain, promotes the conversion efficiency of sugar, fat, and protein, with biological activity approximately 40% higher than ordinary riboflavin.
-
🛡️
Stability Upgrade Thermally stable under acidic to neutral conditions with enhanced light-resistant decomposition capability, making it convenient for processing, storage, and multi-scenario applications.

Frequently Asked Questions
Q1
What is Riboflavin Sodium Phosphate (R5P) and how does it differ from regular riboflavin?
Riboflavin Sodium Phosphate (R5P) is a phosphorylated, water-soluble derivative of vitamin B2 (riboflavin). Unlike ordinary riboflavin, R5P has dramatically higher water solubility (up to 50 mg/mL), enabling it to be formulated into injections and eye drops. Its biological activity is also approximately 40% higher, making it significantly more effective for clinical and nutritional use.
Q2
What are the main health benefits of Riboflavin Sodium Phosphate?
R5P supports energy metabolism by activating mitochondrial ATP synthesis, provides antioxidant protection against free radicals, promotes healing of oral and gastrointestinal mucosa, maintains retinal health and visual function, and enhances iron absorption to assist with iron deficiency anemia.
Q3
In which industries is Riboflavin Sodium Phosphate commonly used?
R5P is widely applied across multiple sectors: in the medical field for treating vitamin B2 deficiency; in the food industry as a nutritional enhancer in dairy products and grains; in cosmetics to improve skin barrier function; and in animal nutrition to enhance the growth performance of livestock and poultry.
Q4
Is Riboflavin Sodium Phosphate stable during storage and processing?
Yes. Riboflavin Sodium Phosphate demonstrates improved thermal stability under acidic to neutral conditions compared to ordinary riboflavin. It also exhibits enhanced resistance to light-induced decomposition, making it easier to handle during manufacturing, storage, and application across multiple product formats.
Q5
How does Riboflavin Sodium Phosphate support energy metabolism at the cellular level?
R5P serves as a direct precursor to the coenzymes FAD (flavin adenine dinucleotide) and FMN (flavin mononucleotide), which are essential components of the cellular respiratory chain. By activating mitochondrial oxidative phosphorylation, R5P improves ATP synthesis efficiency, thereby enhancing physical endurance and accelerating recovery from fatigue.
Q6
Can Riboflavin Sodium Phosphate replace ordinary vitamin B2 in supplement formulations?
Absolutely. Due to its superior bioavailability, higher water solubility, enhanced metabolic activity, and broader dosage form flexibility (including injectable forms), Riboflavin Sodium Phosphate is considered the preferred upgrade and replacement for conventional vitamin B2 in both pharmaceutical and nutraceutical formulations.
