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]^{[verification needed]}

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