Research & Evidence
Campesterol is one of the major dietary phytosterols, structurally similar to cholesterol but of plant origin, and it is found widely across vegetables, grains, legumes and vegetable oils. Like other plant sterols it competes with cholesterol for absorption in the gut, which is the basis for the cholesterol-lowering claims made for phytosterol-enriched foods.
Toxicity & Safety
Campesterol is a normal part of the diet and is considered well tolerated. Plant sterols as a group are widely used in functional foods to help lower LDL cholesterol; the rare inherited disorder sitosterolemia, in which plant sterols accumulate abnormally, is the main context in which dietary phytosterols are restricted.
