Benefits
Healthy cholesterol
Plant sterols are well documented to lower LDL (bad) cholesterol at about 2 grams per day, a benefit recognized by major reviews and regulatory authorities.
Cardiovascular support
Plant sterols reliably lower LDL cholesterol as part of a heart-healthy diet. The LDL-lowering effect is well established and regulator-recognized, though outcome trials have not shown that plant sterols reduce cardiovascular events.
Complements diet and medication
Plant sterols add to the cholesterol-lowering effect of a healthy diet and can complement cholesterol medication under medical guidance.
Mechanism of action
Blocked cholesterol absorption
Plant sterols compete with cholesterol for uptake in the intestine, reducing the amount of dietary and biliary cholesterol absorbed.
Increased LDL clearance
Lower absorption prompts the liver to pull more LDL cholesterol from the blood.
Clinical trials

Adults across the evidence base.
About 2 grams per day of plant sterols consistently lowered LDL cholesterol; the LDL benefit is well documented, though reduced cardiovascular events have not been demonstrated in outcome trials.
