Description

β-Sitosterol is a naturally occurring phytosterol, a plant-derived compound structurally similar to cholesterol. It is valued for its functional properties as a cholesterol-lowering agent and its role as a key intermediate in the synthesis of steroid hormones. This high-purity ingredient is essential for manufacturers in the pharmaceutical, nutraceutical, and cosmetic industries, where it is used to formulate products supporting cardiovascular, prostate, and immune health.

Application

• Nutraceutical & Dietary Supplements: Primary ingredient in cholesterol management and prostate health formulations (e.g., β-sitosterol complexes).
• Pharmaceutical Intermediates: Key starting material for the semi-synthesis of various steroid-based active pharmaceutical ingredients (APIs).
• Cosmetics & Personal Care: Used in anti-aging and skin barrier repair creams for its soothing and moisturizing properties.
• Food & Beverage Fortification: Incorporated into functional foods, such as margarines and dairy products, for cholesterol-lowering claims (plant sterol esters).
• Research & Development: Standard reference compound for analytical studies in lipid metabolism, endocrinology, and plant biochemistry.
• Animal Feed Additives: Used to improve feed efficiency and support animal health in premium livestock nutrition.
