Vitaminwater Fans Upset Over New Sweetener

Fans of Vitaminwater are demanding that parent company Coca-Cola drop a new formula that uses stevia, a low-calorie sweetener known for its metallic aftertaste.

Coca-Cola Co. changed the formula for its full-calorie Vitaminwater in May, and the new bottles have been hitting shelves nationwide ever since.

Previously, the drinks were sweetened with a mix of crystalline fructose and sugar. Now they are sweetened with a mix of sugar and stevia, a natural sweetener companies use to reduce the sugar content in drinks. The new Vitaminwater still has the same 120 calories per bottle, however.
