Diet Coke Plus (also known as Coca-Cola Light Plus) is a formulation of Diet Coke fortified with vitamins and minerals. It is sweetened with a blend of aspartame and acesulfame potassium, unlike regular Diet Coke which only contains aspartame. The drink was released in the United Kingdom in October 2007, available in two variants, one with vitamins B3, B12, and vitamin C, and the other containing antioxidants with added green tea and vitamin C. Although Diet Coke Plus Antioxidants is labeled as sugar free, it actually contains 0.1 grams of sugar in the green tea powder per 100ml.
On December 10, 2008 the United States Food and Drug Administration wrote a Warning Letter to The Coca-Cola Company that Diet Coke Plus violates the Federal Food, Drug, and Cosmetic Act. The term "plus" is a regulated term on food and beverages. A food may be labeled "plus" to describe its nutrients only if it contains at least 10% more of the Reference Daily Intake or Daily Reference Value compared to the usual amount. Because Diet Coke Plus labeling does not indicate the increased amount of nutrients, it cannot use the word "plus" on its label. The FDA required The Coca-Cola Company to detail corrective action within 15 days. Coca-Cola (KO.N) won the dismissal of a lawsuit accusing it of deceiving consumers into believing its Diet Coke Plus cola drink is healthy. "At most, plaintiffs simply claim that their expectations of the soda were disappointed," the judge wrote in his ruling Thursday. "Dissatisfaction with a product, however, is not a quantifiable loss that can be remedied."
