Plant sterols (also known as phytosterols) are natural substances found in plants that decrease the absorption of cholesterol in the intestines, in turn lowering your cholesterol and risk of developing coronary heart disease. The easiest way to introduce plant sterols into your diet is with a daily supplement, as it's difficult to get the levels you need from food alone

*800mg plant sterols a day (1 tablet) helps to maintain normal cholesterol levels [see https://doi.org/10.2903/j.efsa.2010.1813].
Cholesterol-lowering benefit obtained with an intake of 1,500-3,000mg plant sterols (2-3 tablets a day) [see https://doi.org/10.2903/j.efsa.2009.1177].
