1-(3-methoxybenzyl)-3-substituted thiourea antioxidant compounds and
improved lipids compositions which are supplemented with amounts of such
antioxidant compounds effective for augmenting oxidative stability of the
base lipid are provided. Also provided are methods for enhancing the
oxidative stability of a lipid comprising supplementing a base lipid in
need of enhanced oxidative stability with at least one
1-(3-methoxybenzyl)-3-substituted thiourea compound of the present
invention.
