CardioAid® (Plant Sterols — ADM)

Evidence Level
Strong
1 Clinical Trial
3 Documented Benefits
4/5 Evidence Score

CardioAid® is a plant sterol (phytosterol) ingredient from ADM, used to support healthy cholesterol. Plant sterols are among the best-established functional ingredients for cholesterol management: they block the absorption of dietary cholesterol in the gut, and authorities recognize their LDL-lowering effect.

Studied Dose About 2 grams of plant sterols per day with meals.
Active Compound Plant sterols (phytosterols) such as beta-sitosterol, campesterol, and stigmasterol.

Benefits

Healthy cholesterol

Plant sterols are well documented to lower LDL (bad) cholesterol when taken at about 2 grams per day, a benefit recognized in major reviews and by regulatory authorities.

Cardiovascular prevention

By lowering LDL cholesterol, plant sterols support long-term cardiovascular health as part of a heart-healthy diet.

Complements diet and statins

Plant sterols add to the cholesterol-lowering effect of a healthy diet and can complement cholesterol medication under medical guidance.

Mechanism of action

1

Blocked cholesterol absorption

Plant sterols compete with cholesterol for uptake into intestinal cells, reducing the amount of dietary and biliary cholesterol absorbed.

2

Increased cholesterol clearance

Lower absorption prompts the liver to pull more LDL cholesterol from the blood, lowering circulating levels.

About 2 grams per day of plant sterols consistently lowered LDL cholesterol, supporting cardiovascular prevention.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated — well tolerated at recommended intakes.
May slightly lower absorption of fat-soluble vitamins and carotenoids; eat plenty of produce.
Mild digestive upset is occasionally reported.

Important Drug interactions

Ezetimibe — both reduce cholesterol absorption; consult your doctor.
