What Are Phytosterols?
Phytosterols, also known as plant sterols, are naturally occurring compounds found in plants that have a similar structure to cholesterol. When consumed, they compete with cholesterol for absorption in the small intestine, effectively reducing the amount of cholesterol that enters your bloodstream.
Key Point: These plant-based compounds are particularly effective at lowering LDL (bad) cholesterol levels, making them valuable allies in cardiovascular health management.
