Beta sitosterol is a phytosterol-a plant compound with a chemical structures similar to that of cholesterol. Phytosterols inhibit the intestinal absorption of cholesterol.
Clinical trials have shown that eating foods enriched with at least 0.8 g of plant sterols or stanols helps to lower serum LDL cholesterol. Other studies have shown beta-sitosterol may help to fight cancer by causing apoptosis (cell suicide) in breast, colon and prostate cancer cells.
