Product Overview

     Niacin (Nicotinic Acid, Vitamin B3) is a water-soluble B-complex vitamin essential for cellular energy metabolism, DNA repair, and lipid regulation. The essential downstream application of vitamin B3 is feed, accounting for 67%; followed by pharmaceuticals and cosmetics, and food, accounting for 20% and 13% respectively.

     As a professional Niacin manufacturer, Henan Liyin Biotech supplies high-purity Niacin powder (≥99.5%) in three dedicated grades — Feed Grade, Food Grade, and Personal Care Grade — each manufactured under strict GMP guidelines and compliant with USP, BP, and FCC standards.

• In animal feed, Niacin plays a vital role in energy metabolism, promoting growth and improving feed conversion rates in poultry and swine.
• As a food fortificant, it helps prevent pellagra and supports normal nervous system function.

Animal Nutrition

Niacin is an essential nutrient for poultry, swine, and other livestock, playing a critical role as a precursor to the coenzymes NAD (Nicotinamide Adenine Dinucleotide) and NADP (Nicotinamide Adenine Dinucleotide Phosphate) . These coenzymes are fundamental to cellular energy metabolism, facilitating the oxidation of carbohydrates, fats, and proteins for energy production. Niacin also supports lipid metabolism, helping to reduce body fat deposition and improve feed efficiency.

Key Benefits: Promotes growth performance, improves feed conversion rates, and supports skin and digestive health. In poultry, it helps prevent deficiency symptoms such as poor growth, inflammation of the digestive tract, and feathering issues. In swine, it supports overall health and reproductive performance.

Recommended Inclusion Rates: Typical supplementation levels range from 30–50 mg/kg of complete feed for broilers, layers, and finishing pigs, depending on species, age, and production stage. In high-energy diets, requirements may increase, and levels up to 60 mg/kg may be recommended.

Formulation Advantage: Our Feed Grade Niacin is formulated for optimal dispersion in premixes and pelleted feeds, ensuring uniform distribution and consistent efficacy.

Human Food & Supplements

In human nutrition, Niacin (Nicotinic Acid) is a water-soluble vitamin essential for energy metabolism, DNA repair, and lipid regulation. It is a mandatory fortificant in many countries, added to staple foods to prevent pellagra — a deficiency disease characterized by dermatitis, diarrhea, and dementia — and to support normal nervous system function.

Food Fortification: Widely used to enrich wheat flour, cornmeal, cereals, and rice to meet regulatory nutrition standards. Typical fortification levels range from 15–20 mg/kg in wheat flour, depending on national regulations. For example, in the United States, enriched flour is fortified at 24-28 mg/kg (as niacin equivalents).

Dietary Supplements: A key ingredient in B-complex vitamins and multivitamin formulations, supporting energy metabolism and cardiovascular health. Typical dosages in supplements range from 15–100 mg per serving for general wellness, with higher doses (up to 500 mg) used in specialized formulations for lipid management (as nicotinic acid).

Formulation Stability: Our Food Grade Niacin demonstrates excellent stability in dry, heat-processed foods and is compatible with other B-vitamins commonly used in fortification blends. For dietary supplements, both immediate-release and sustained-release formulations can be developed.

Pharmaceutical Intermediates

Niacin serves as a precursor for the synthesis of certain active pharmaceutical ingredients (APIs) and is itself used as an active ingredient in prescription and over-the-counter products. Its role in lipid metabolism makes it a valuable compound for cardiovascular health applications.

Key Applications: Used as an intermediate in the synthesis of niacinamide and other pharmaceutical compounds. Also formulated as an active ingredient in products for cholesterol management (e.g., extended-release niacin tablets for dyslipidemia treatment).

Quality Requirements: Pharmaceutical applications require the highest purity and strict compliance with pharmacopoeia standards (USP, BP, EP). Our Niacin meets these stringent requirements, with guaranteed assay of ≥99.5% and rigorous testing for related substances, heavy metals, and residual solvents.

Customization: We can supply Niacin in various particle sizes and specifications to meet specific pharmaceutical formulation needs, from powder blends to granulations.
