Phytosterols are a naturally sourced plant ingredient that works with your body to help reduce cholesterol absorption. Because phytosterols are structurally similar to cholesterol, they can help form a physical barrier that blocks the absorption sites where harmful excess cholesterol would otherwise enter the bloodstream.
To achieve this beneficial effect, phytosterols must be consumed in sufficiently high amounts—two grams per day, according to leading researchers.1 While phytosterols occur naturally in many healthful foods, it would be virtually impossible to consume enough phytosterols in their naturally existing forms to achieve a cholesterol-lowering benefit. In fact, you'd have to eat 150 apples, 70 slices of whole-grain bread or 450 tomatoes to get the same amount of phytosterols in three delicious servings of Silk® Heart Health!
