R5P (Riboflavin 5-phosphate)

R5P (riboflavin 5'-phosphate) is the phosphorylated form of riboflavin (vitamin B2), also known as flavin mononucleotide (FMN), supplied by Nustras as riboflavin 5'-phosphate sodium, a yellow to orange-yellow crystalline powder, for the vitamin and supplement market. The sodium salt is appreciably more water-soluble than riboflavin itself.

It is formulated into B-complex and multivitamin supplements in tablet, capsule, liquid and powder form, into vitamin premixes, and into fortified beverages and functional foods where a soluble form of vitamin B2 is required.

The material is a yellow to orange-yellow crystalline powder, hygroscopic and light-sensitive, complying with the USP monograph for riboflavin 5'-phosphate sodium. Riboflavin content (dry basis), water, free riboflavin and other related compounds, and pH are standardised to specification; identity is confirmed by infrared spectroscopy and assay by high-performance liquid chromatography, and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis. Storage protected from light is recommended.

Nustras supplies riboflavin 5'-phosphate sodium in bulk commercial quantities, in sealed packaging and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Riboflavin 5'-phosphate sodium is a permitted vitamin B2 source in major supplement and food markets; buyers confirm the riboflavin-equivalent contribution and permitted level for their application.
