The secret to MiO is sucralose, a calorie-free sweetener that's safe for diabetics (it has no effect on insulin levels) and does not promote dental cavities (but you'll still have to brush and floss). Sucralose has been around since the late 50's and has found its way into more than 4,500 different foods and beverages. But with MiO, you're in control of harnessing its power to make something that tastes incredible to you.
