Product Overview 

Vitamin B2 (Riboflavin) is an essential water-soluble vitamin that serves as the direct precursor to the coenzymes FMN (flavin mononucleotide) and FAD (flavin adenine dinucleotide) . These coenzymes are critical for cellular energy production, functioning as electron carriers in the oxidation of carbohydrates, fats, and proteins via the Krebs cycle. Riboflavin is also vital for maintaining healthy skin, eyes, and the nervous system.

At Henan Liyin Biotech, we supply high-purity Vitamin B2 in a free-flowing, yellow crystalline powder form. Our product is available in both Feed Grade and Food Grade specifications and is manufactured to meet the strict requirements of USP, EP, and FCC standards.

Our technical team is available to assist with application guidance, formulation support, and custom packaging solutions — from R&D trials to full-scale commercial production.

Why Choose Our Vitamin B2?

Verified High Purity: Assay ≥98.0% by HPLC, with typical batch results exceeding 99.0%, ensuring consistent potency for your formulations.

Excellent Flowability: 100% passes through an 80-mesh sieve, guaranteeing easy dispersion and homogeneous mixing in feed premixes, food blends, and supplement tablets.

Proven Stability: Maintains full label claim potency for up to 24 months under recommended storage conditions (cool, dry, protected from light).

Complete Traceability: Each batch is accompanied by a comprehensive Certificate of Analysis (COA), including rigorous testing for heavy metals (Pb≤2ppm, As≤1ppm), microbiological contaminants, and residual solvents.

Flexible Packaging: Available in 25kg cardboard drums or cartons, with customization options to suit your logistics requirements.

Animal Feed

In poultry, swine, and ruminant nutrition, Riboflavin is indispensable for growth, feed efficiency, and overall flock or herd health. As a precursor to FMN and FAD, it plays a non-negotiable role in energy metabolism — facilitating the breakdown of dietary proteins, fats, and carbohydrates for fuel.

Deficiency Prevention: Adequate riboflavin levels are critical to prevent common deficiency syndromes, including poor growth, dermatitis, and reduced hatchability in breeding stock. In poultry, deficiency can lead to "curled-toe paralysis," a classic sign of impaired nerve function.

Recommended Inclusion: Typical supplementation levels range from 2–8 mg/kg in complete feed for poultry and swine, depending on age, production stage, and dietary composition.

Formulation Advantage: Our product's 80-mesh particle size ensures excellent flowability and even distribution in vitamin premixes, minimizing segregation during mixing and handling.

Food Fortification

Riboflavin serves a dual purpose in the food industry: as a nutrient fortificant and as a natural yellow colorant (E101) . Its excellent stability in dry and heat-processed foods makes it a versatile choice for product developers.

Key Applications: Widely used to enrich cereals, flours, pasta, breakfast cereals, and infant formulas to meet regulatory fortification requirements and improve nutritional profiles.

Typical Fortification Levels: In wheat flour, levels of 1.2–4.0 mg/kg are common, while ready-to-eat cereals may contain 1.0–2.0 mg/kg. Infant formula fortification is strictly regulated and typically ranges from 0.4–1.5 mg/kg.

Consumer Appeal: As a natural-source colorant, it provides a warm, appetizing yellow hue to processed foods, aligning with the growing consumer demand for clean-label ingredients.

Dietary Supplements

Riboflavin is a core component of high-quality multivitamin and B-complex formulations, valued for its role in energy production, cellular function, and antioxidant defense (as part of the glutathione redox cycle). It is commonly combined with other B-vitamins, particularly vitamin B6 and niacin, with which it exhibits excellent formulation compatibility and synergistic effects.

Target Formats: Available in tablets, capsules, and powder blends for human nutrition, often at dosages ranging from 1.2–20 mg per serving (depending on the target population and product positioning).

Formulation Stability: Our Riboflavin demonstrates good stability in dry, solid dosage forms when protected from light, making it a reliable choice for supplement manufacturers.
