Abstract: The present invention provides compositions for and methods of delivering a therapeutically-effective dose of a malodorous, sulfide or disulfide group-containing compound, for example glutathione (reduced) and/or glutathione disulfide, in a vehicle that is effective to reduce the unpleasant odor and/or taste of the compound. The invention further provides methods for reducing the amount of oxidation occurring when sulfide group-containing compounds, such as glutathione, are incorporated into sugar and or sugar-free hard candies without subjecting the glutathione to thermal and or moisture degradation where degradation is expressed as oxidation. The invention further provides vehicle compositions including the protected sulfide group-containing compounds and their use as medicaments. The sulfide group-containing compounds are protected from degradation by their dispersion into fats, oils, and/or fractionated or partially hydrogenated oils prior to their blending into the vehicle.

Abstract: A multiple-layer edible tablet is provided which contains a combination of different ingredients in separate layers wherein ingredients in one of the layers exhibits distinct organoleptic characteristics such as being perceived as cooling in contrast to the distinct organoleptic characteristics exhibited by the ingredients is another of the layers of the tablet such as being perceived as warming to enable the separate layers of the tablet to be identified when the tablet is being consumed by a user.
