Product Usage

Nicotinic Acid, commonly known as Vitamin B3 or Niacin, is a vital nutrient with diverse applications across multiple industries. In the pharmaceutical and nutraceutical sectors, it is primarily used to treat pellagra and as a lipid-lowering agent to improve cholesterol profiles by reducing LDL and increasing HDL levels. Its role in the food industry is equally critical, where it serves as a fortification agent in cereals, flour, and infant formulas to prevent nutritional deficiencies. In the animal feed industry, it is an essential additive for livestock and poultry to promote healthy growth and metabolic efficiency. Furthermore, nicotinic acid is increasingly utilized in cosmetics and skincare (often as its derivative niacinamide) to enhance skin barrier function, improve elasticity, and even out skin tone.
