The present invention relates to compositions and methods that utilize dietary electrolyte salts to improve the flavor of high-potency sweeteners and to enhance the synergistic effects between high-potency sweeteners and carbohydrate sweeteners. Specific dosage levels of dietary potassium and sodium have been discovered that correct the flavor deficits of existing high-potency sweeteners related to off-flavor, after-taste, thin mouth-feel, and loss of sweetness at high doses. In addition, these dosage levels of dietary electrolytes amplify the synergy between high-potency sweeteners and trace quantities of carbohydrate sweeteners. Consequently, electrolyte-enhanced sweetener compositions elicit sweetness, flavor, and mouth-feel profiles nearly indistinguishable from pure sugar. These compositions possess negligible calories and are compatible with a wide range of foods, beverages, serving, and preparation conditions and with food labels related to natural, organic, GMO free, allergen free, and gluten free.
