Phytosterol esters are compounds formed by esterifying phytosterols (plant sterols) with fatty acids.
They are widely used in functional foods and supplements due to their cholesterol-lowering properties.
Naturally found in small amounts in:
Vegetable oils (soybean, corn, rapeseed)
Nuts and seeds
Whole grains
Commercially produced by esterifying phytosterols (from soybean or pine tree extracts) with fatty acids (e.g., from sunflower or canola oil).

Reduce LDL ("bad") cholesterol by 10–15% when consumed at 2–3 g/day.
Mechanism: Phytosterols compete with cholesterol for absorption in the intestines, reducing dietary cholesterol uptake.
May lower the risk of atherosclerosis and heart disease when combined with a healthy diet.
Some studies suggest phytosterols may reduce inflammation and oxidative stress.
Fortified foods: Margarine, yogurt, milk, orange juice.
Dietary supplements: Softgels, capsules.
Functional foods: Often used in products marketed for heart health.

Not recommended for:
People with sitosterolemia (a rare genetic disorder causing excessive phytosterol accumulation).
Pregnant or breastfeeding women (due to limited safety data).
