Stigmastanol (sitostanol) is a phytosterol found in a variety of plant sources. Similar to sterol esters and stanol esters, stigmastanol inhibits the absorption of cholesterol from the diet.[2][3][4] Animal studies suggest that it also inhibits biosynthesis of cholesterol in the liver.[2]

Stigmastanol is the product of the reduction of β-sitosterol[5] and the hydrogenation of stigmasterol.[6]
