Is exogenous lanosterol a micronutrient?

Lanosterol, a precursor of cholesterol, is ingested with human diet and occurs in the body in concentrations exceeding solubility. Flesh of immature animals is a common source of dietary lanosterol, which may form with cholestanol and water an insoluble adjunct, CL-2W. As the latter may contribute to various disorders, exogenous lanosterol should be avoided by diet adjustment.
