Plant stanol ester is the active ingredient in Benecol® foods

Plant stanols are plant-based compounds naturally found in foods. Structurally they resemble cholesterol. Plant stanols are found in all plant foods in both free and esterified forms. The main dietary sources are whole-grain foods. Daily intake of stanols from an average diet is about 30-50 mg/d1 which is far too low to have an effect on serum cholesterol levels.
