Its primary industrial use is as a starting material (precursor) in the semi-synthesis of steroid hormones like progesterone and vitamin D derivatives for pharmaceuticals.
As a natural component of many plant foods (soybeans, nuts), it is generally considered safe. In concentrated supplemental form, it is subject to regulatory evaluation, but plant sterols are often added to foods for their cholesterol-lowering potential.
