Phytosterols are widely used in the food and healthcare industries due to their cholesterol-lowering properties. They are incorporated into functional foods such as margarine, spreads, and dairy products to help reduce LDL cholesterol levels in the blood. In dietary supplements, phytosterols are often included to support cardiovascular health. Additionally, they are utilized in cosmetics and skincare products for their anti-inflammatory and moisturizing effects, helping to improve skin barrier function and reduce irritation. In the pharmaceutical industry, phytosterols are explored for their potential in managing conditions like benign prostatic hyperplasia and as natural additives in drug formulations.
