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

In animal nutrition, adequate riboflavin levels are crucial for:

Supporting growth and feed efficiency in poultry, swine, and ruminants.

Preventing common deficiency symptoms, such as poor growth, dermatitis, and reduced hatchability in breeding stock.

As a food ingredient, it provides both nutritional fortification and the natural yellow color (E101) valued in many processed foods.

Key Product Features:

High Purity: Assay ≥98.0% (typical results >99% by HPLC).

Excellent Flowability: 100% passes through an 80-mesh sieve, ensuring easy dispersion in premixes and formulations.

Proven Stability: Maintains potency for 24 months under recommended storage conditions.
Animal Feed: An essential vitamin for poultry and swine, supporting growth, feed efficiency, and overall flock/ herd health. Commonly incorporated into vitamin premixes.

Food Fortification: Used to enrich cereals, flours, pasta, and infant formulas. Also serves as a natural yellow food colorant (E101).

Dietary Supplements: A key ingredient in multivitamin and B-complex formulations for human nutrition.

Technical Support: We provide full documentation including COA, MSDS, flow agent, and allergen statements to support your regulatory compliance needs.
