Phytosterols are commonly referred as Plant Sterols and Plant Stanol. They have molecular structure similar to cholesterol. Sterols are isolated from vegetable oils. When they are consumed, they compete with cholesterol for absorption in the digestive system and reduces absorption of cholesterol in the gut thereby lowers blood cholesterol levels.
Sterol consumption reduces cholesterol up to 10 percent and LDL or “bad” cholesterol up to 14 percent.
