The two food substance of 300mg beta-sitosterol and 30mg citrus pectin are known cholesterol lowering agents that, when combined together, alter dietary fat and cholesterol absorption.

• intestinal binding excretion of free cholesterol
• blocking of absorption sites in the intestinal walls
• an enzymatic shift decreasing liver cholesterol production
• increased liver enzyme functions on the breakdown of fats
