Plant sterols [1] (English: Phytosterol, also known as plant sterols) are present in higher plants sterols. In clinical trials, plant sterols shown to block the human intestinal cholesterol absorption sites, and therefore helps to reduce cholesterol levels in humans [2]. They have also been recognized by the United States Food and Drug Administration, can be used as a food additive; however, some people worry that they may not only block the absorption of cholesterol, but may also block the absorption of other important nutrients. Currently, the American Heart Association has recommended only been diagnosed with elevated cholesterol should be added when the plant sterols, especially not recommended for pregnant women or nursing mothers edible steroids [3].

The US Food and Drug Administration (FDA) is respected plant sterols to "reduce cholesterol, prevent arteriosclerosis" natural health food. Plant sterols are a class of biologically active substances using supercritical carbon dioxide extraction technology to extract derived directly from plants it does not contain any organic solvents and metal ions and other impurities can be widely used in medicine, food and feed!
