Diet Supernova

Diet Supernova was the diet version of Supernova that was released during the FanDEWmonium and won, which would have made it a permanent flavor. However, it was discontinued after 12 weeks into its store release due to low sales.


Diet Supernova was the same flavor and color as regular Supernova but used a low-calorie formula.


Its tagline was "Strawberry-melon Diet Dew."


Diet Supernova was originally released to taste testers as one of eight new diet flavors with a chance to become a permanent flavor. Eventually, it and Diet Voltage (both diet versions of flavors from DEWmocracy I) made it to the finals and were officially released to store shelves in March 2011.

Diet Supernova won FanDEWmonium with 55% of all votes, which resulted in it becoming a permanent Diet Flavor. In January 2012, months after it was announced the winner, Diet Mountain Dew Supernova was returned to store shelves and was featured in the Fuel the Frenzy promotion. Afterward, it was removed from shelves permanently due to low sales during the promotion.

However, it remained listed an option on the Official Mountain Dew Locator website (although it did not have locations) until mid-2014. Some fans reported being able to locate Diet Supernova in various scattered locations until at least 2014.


  • Diet Supernova was the first flavor to win a vote in the United States to become a permanent flavor and later be discontinued, followed by White Out and Pitch Black.
