Description

β-Sitosterol is a naturally occurring phytosterol, a plant-derived compound with a chemical structure similar to cholesterol. It is valued for its versatile functional properties, including its role as a cholesterol-lowering agent and a precursor in the synthesis of other steroidal compounds. This high-purity ingredient is essential for manufacturers in the pharmaceutical, nutraceutical, cosmetic, and food industries seeking to enhance product efficacy and meet consumer demand for natural, plant-based solutions.

Application

• Pharmaceutical Intermediates: Serves as a key starting material for the semi-synthesis of steroidal drugs and active pharmaceutical ingredients (APIs).
• Dietary Supplements & Nutraceuticals: Formulated into capsules, tablets, and functional foods for its well-researched role in supporting cardiovascular health by helping to maintain healthy cholesterol levels.
• Cosmetics & Personal Care: Incorporated into creams, lotions, and serums for its skin-conditioning, anti-inflammatory, and moisturizing properties.
• Food Additives & Fortification: Used as a functional food ingredient in spreads, dairy products, and beverages for cholesterol reduction claims and to enhance nutritional profiles.
• Research & Development: Employed as a standard or reagent in biochemical research, clinical studies, and analytical laboratories.
• Animal Nutrition: Used in feed additives to promote growth and improve lipid profiles in livestock.
