Stigmastanol is primarily used in the food and health industries due to its cholesterol-lowering properties. It is often incorporated into functional foods, such as margarines, spreads, and dairy products, to help reduce the absorption of dietary cholesterol in the intestines. This makes it beneficial for individuals aiming to manage or lower their blood cholesterol levels. Additionally, stigmastanol is utilized in dietary supplements designed to support cardiovascular health. Its ability to block cholesterol absorption without being absorbed itself enhances its safety and effectiveness as a health-promoting compound.
