Phytosterols are natural components found in a number of vegetables, plants and grains, and they may help support balanced cholesterol levels.
And, recent studies have shown the amazing benefits of plant sterols regarding the absorption of cholesterol. Hot off the presses, the Sept./Oct. issue of the Annals of Nutrition & Metabolism published a study evaluating the effects of certain plant sterols on human cholesterol absorption. Twenty-four men and women underwent four separate tests that included different doses of phytosterols. The tests showed that 300 mg of phytosterols reduced cholesterol absorption by over 23%; a dose of 500 mg reduced the absorption by 32%.
