Description

Riboflavin 5'-Sulfate, also known as flavin mononucleotide (FMN), is a crucial phosphorylated derivative of riboflavin (Vitamin B2). This compound serves as the biologically active coenzyme form of vitamin B2, essential for numerous redox reactions in cellular metabolism. It is a vital ingredient for manufacturers in the pharmaceutical, nutraceutical, and food & beverage industries seeking to formulate high-quality enzyme supplements, clinical nutrition products, and fortified foods.

Application

• Pharmaceutical Formulations: Used as an active pharmaceutical ingredient (API) in vitamin B complex injections, tablets, and capsules for treating riboflavin deficiency.
• Clinical & Enteral Nutrition: A key component in parenteral (IV) and enteral feeding solutions to ensure adequate micronutrient intake for patients.
• Dietary Supplements: Incorporated into multivitamin and B-complex supplements due to its superior bioavailability compared to riboflavin.
• Food & Beverage Fortification: Used to fortify infant formula, cereals, dairy products, and energy drinks.
• Cosmetic & Personal Care: Applied in skincare formulations for its antioxidant properties and role in promoting skin health.
• Biochemical Research: Serves as a critical cofactor (FMN) in enzymatic assays and studies of flavoprotein enzymes.
• Animal Feed & Nutrition: An essential vitamin supplement in premixes for livestock, poultry, and aquaculture to support growth and health.
