  • Applications

    Beta-Sitosterol (CAS 83-46-5) is a plant-derived phytosterol used widely: in fortified foods and dietary supplements to help lower LDL cholesterol by competitively inhibiting intestinal cholesterol absorption, commonly incorporated into sterol-enriched margarines, dairy products, and beverages; in men’s health to support relief of benign prostatic hyperplasia (BPH) symptoms via anti-inflammatory activity and modulation of 5-alpha-reductase, often combined with saw palmetto or pygeum; in cardiometabolic support as a component for lipid management and vascular health; in pharmaceuticals/nutraceuticals as tablets, softgels, and microencapsulated powders; in cosmetics for skin and hair care as an emollient that strengthens the barrier, reduces irritation, and provides antioxidant benefits, used in creams, lipsticks, sunscreens, and scalp-soothing formulas; in formulation science as a cholesterol substitute to tune bilayer properties of plant-based liposomes/niosomes; and in chem/pharma as a plant-oil–sourced raw material enabling semisynthesis of certain steroids, with an established safety profile under multiple food phytosterol regulatory frameworks.
