Sweet taste receptor antagonist compositions

Abstract

The present disclosure relates to compositions comprising gymnemic acid, together with a form of zinc to block the unpleasant bitter taste of gymnemic acid as well as to extend the sweet taste blocking properties of gymnemic acid, resulting in palatable compositions for delivery to the oral cavity to block sweet taste receptors located therein. The present disclosure also relates to methods of reducing sugar consumption and reducing calorie intake via administration of such compositions to a subject.
