Alone and in combination with similar phytosterols, β-sitosterol reduces blood levels of cholesterol, and is sometimes used in treating hypercholesterolemia.β-Sitosterol inhibits cholesterol absorption in the intestine.When the sterol is absorbed in the intestine, it is transported by lipoproteins and incorporated into the cellular membrane.[3] Phytosterols and phytostanols both inhibit the uptake of dietary and biliary cholesterol, and reduce the levels of LDL and total serum cholesterol. Because the structure of β-sitosterol is similar to that of cholesterol, β-sitosterol takes the place of dietary and biliary cholesterol in micelles produced in the intestinal lumen.This reduces cholesterol absorption in the body.
