Diet Mountain Dew is a Mountain Dew variant with only ten calories, compared to the 290 calories in the original, and is sweetened with artificial sweeteners instead of Corn Syrup or Sugar.


Diet Mountain Dew is a modified version of the original formula, containing low sugar count but retaining the same citrus taste and yellow-green color as the original Mountain Dew drink, similar to, but a separate drink from, Mountain Dew Zero Sugar.


Its tagline is "Low Calorie DEW."


Diet Mountain Dew was first introduced alongside Caffeine-Free Mountain Dew in 1976 in response to the growing trend in America of weight-watching. It used to be branded as Sugar-Free Mountain Dew until 1984 when it got renamed to Diet Mountain Dew, its current name.

In 2006, Diet Mountain Dew received a formula change by PepsiCo created a new and improved formula called a "Tuned Up Taste." This "Tuned Up Taste" uses a blend of sweeteners named sucralose, aspartame, and acesulfame potassium. The previous formulation was sweetened exclusively with aspartame.

Main article: Mountain Dew Zero Sugar

Starting in January 2020, Mountain Dew Zero Sugar got released in the United States. Before its introduction, people were worried that it would replace Diet Mountain Dew as the new low sugar drink in the United States. It got confirmed by a PepsiCo employee that there weren't any plans for Zero Sugar to replace Diet Mountain Dew. Instead, it will coexist with it. As of October 2021, Diet and Zero Sugar are still available for Americans to enjoy.

International Release


At some point during the 1990s, Diet Mountain Dew was getting sold in Canada. This version got sold without caffeine due to laws preventing caffeine from being added to non-dark soft drinks.

It is unknown when it got discontinued, but it returned in 2012 as Diet Mountain Dew Citrus Charge, to match the Citrus Charge branding shift when laws changed and Mountain Dew added caffeine like in other countries.

In 2017, the Diet Mountain Dew Citrus Charge branding got branded to its American counterpart known as Diet Mountain Dew in English and as Mountain Dew Diète in French.

At the start of April 2020, following the American release of Mountain Dew Zero Sugar in January 2020, Mountain Dew Zero Sugar replaced Diet Mountain Dew rather than coexist with Diet. It got only released in 12 packs.

United Kingdom

In the United Kingdom, the Original Dew was first sold in 1997 alongside the standard variety under the Diet Mountain Dew name before being pulled from the market in 1998 due to low sales.

In 2011, it got re-released in the United Kingdom, branded as Sugar-Free Mountain Dew - Get Energized, being sold in 440ml cans, and later renamed to the standard international name of Mountain Dew All Dew - No Sugar, being expanded to 330ml cans and 500ml bottles.

Denmark and Finland

The drink got sold in Denmark and Finland for an unknown amount of time as Free Mountain Dew. It got later discontinued, but the latter country reintroduced it under the All Dew - No Sugar name in 2020.

United Arab Emirates

It was introduced in the United Arab Emirates in 2012 as Diet Mountain Dew - Dew Does Diet, but it is most likely no longer getting produced over there.

Sweden, Norway, The Netherlands

Throughout the 2010s, it got introduced in the Netherlands, Sweden, and Norway under the All New - No Sugar name and continuing getting produced.

New Zealand

New Zealand introduced the drink sometime in the 2010s as Mountain Dew No Sugar, but when they transitioned to the current logo, it gained the standard All Dew - No Sugar name.


In France, the drink got released in 2018 as Mountain Dew Sans Sucres. It is the only version of the Original Dew available in the country.


In Australia, it was introduced in 2019 and sold as Mountain Dew Energised No Sugar.


In Malaysia, it was introduced in the late 2010s and sold as All New - No Calorie and is still produced as of 2021.


  • In Poland (as New Dew - No Calories), Russia, Romania (both as New Dew - New Taste), Netherlands (as Mountain Dew Citrus Blast - No Sugar Recipe) and Spain (as Mountain Dew Sin Azucar), the diet variety is sold as standard Mountain Dew nowadays. In Poland, it later reverted to the original sugar-sweetened variety after only a year on the shelves.
