1. Product Introduction
Beta-sitosterol (β-sitosterol) is a natural organic tetracyclic triterpenoid compound and the most dominant and active monomer component in natural phytosterols. It presents as white needle-like or scaly crystals, or white crystalline powder, which is odorless and tasteless in appearance. In terms of physical solubility, it is insoluble in water, slightly soluble in ethanol and acetone, and easily soluble in chloroform, with stable physical and chemical properties.
As a safe and edible natural plant active ingredient, beta-sitosterol has excellent physiological activities including blood lipid regulation, antioxidant and anti-inflammatory effects. It features high safety for human metabolism and absorption, and is widely applied in food health products, pharmaceutical industry, cosmetics, agricultural breeding and other fields, being a multi-functional mainstream plant extract raw material.

3. Core Functions & Physiological Efficacy
Beta-sitosterol is a high-value natural functional ingredient with multiple health-care and pharmacological effects, widely recognized and applied in global health and medical industries:
1. Prostate Health Care
It is a classic natural ingredient for improving male prostate health. Scientific studies have verified that beta-sitosterol can effectively relieve prostate discomfort, reduce the incidence of benign prostatic hypertrophy and prostate lesions, and is widely used in male prostate health supplements, providing safe daily conditioning for male urinary and reproductive system health.
2. Prevent Hair Loss & Improve Hair Quality
With excellent anti-inflammatory activity, beta-sitosterol can optimize the microenvironment around hair follicles, promote the proliferation of hair follicle fibroblasts, and inhibit hair follicle inflammation. It effectively improves dry and frizzy hair, increases hair softness and luster, and fundamentally prevents and improves hair loss problems, which is a core functional raw material for anti-hair-loss cosmetics and health products.
3. Lower Blood Lipids & Protect Vascular Health
It has significant blood lipid regulating effect, which can effectively clear vascular garbage, reduce blood lipid deposition, maintain vascular patency, inhibit vascular oxidative damage, and prevent cardiovascular sub-health problems caused by high blood lipids.
4. Antioxidant & Anti-Inflammatory
It can scavenge human oxidative free radicals, reduce inflammatory reactions in the body, relieve skin and tissue inflammation, and improve body antioxidant capacity and immune balance.
4. Wide Application Fields
1. Health Supplement Industry
Relying on the effects of lowering blood lipids, dredging blood vessels and protecting prostate health, it is processed into various dosage forms such as protein powder, capsules and tablets. It is widely used in adult cardiovascular health care and male prostate conditioning health products.
2. Pharmaceutical Industry
It is an important synthetic precursor of steroid hormone drugs, applied in the research and development and production of lipid-regulating drugs and steroid hormone preparations. In addition, it can be used to prepare pharmaceutical liposome carriers, which significantly improves the stability and targeting of liposome membranes, reduces drug toxicity, and is widely used in high-end pharmaceutical delivery systems.
3. Cosmetic & Personal Care Industry
With anti-inflammatory, antioxidant and anti-hair-loss effects, it is added into anti-hair-loss shampoo, hair care lotion and skin repair products to improve scalp microcirculation, repair damaged skin and hair, and improve overall skin and hair condition.
4. Agriculture & Animal Husbandry Industry
It is used as a high-functional feed additive. It can reduce cholesterol content in livestock and poultry meat, eggs and dairy products, promote healthy growth of animals, improve breeding yield, and optimize the nutritional quality of animal-derived food.
